Concord, California's thriving residential and commercial landscape demands concrete work that can withstand the region's unique environmental conditions. Located in the heart of Contra Costa County, Concord experiences hot, dry summers with temperatures regularly exceeding 90 degrees, followed by mild, wet winters that can test the durability of improperly installed concrete. Whether you're planning a new driveway to complement your home in the Vineyard neighborhood, installing a decorative patio in downtown Concord, or need commercial flatwork for a business property near the Concord BART station, selecting the right concrete contractor is crucial for ensuring longevity and aesthetic appeal.

The concrete industry in Concord presents homeowners with numerous options, but not all contractors deliver the same level of expertise, professionalism, or quality. From proper ground preparation to account for the area's expansive clay soils, to understanding Contra Costa County's specific permitting requirements and building codes, experienced local contractors bring knowledge that directly impacts your project's success. Poor concrete work can lead to cracking, settling, drainage issues, and costly repairs—problems that are particularly common when contractors skip essential steps like adequate base preparation or proper reinforcement placement.

This comprehensive guide examines four licensed concrete contractors operating in Concord, California in 2026. We've analyzed their California State License Board credentials, insurance coverage, customer reviews, years of experience, and project portfolios to help you make an informed decision. Each contractor profiled here maintains an active CSLB license, carries the required workers' compensation insurance, and has demonstrated competence through verified customer feedback. Whether you're a first-time homeowner planning your initial concrete project or a property manager overseeing multiple installations, this guide provides the factual information you need to compare your options and select a contractor whose expertise aligns with your specific project requirements and budget.

How We Ranked These Concord Concrete Contractors

Our ranking methodology prioritizes verifiable credentials and authentic customer experiences rather than advertising claims or contractor self-promotion. We began by verifying each contractor's license status through the California State License Board database, confirming active standing, bond amounts, and workers' compensation insurance coverage—non-negotiable requirements for legal operation in California. All contractors featured in this guide maintain the required $25,000 contractor bond and current workers' compensation policies, protecting homeowners from liability in case of on-site injuries.

We analyzed customer reviews from Google and Yelp, examining both quantitative ratings and qualitative feedback content. Rather than simply averaging star ratings, we assessed review recency, consistency of feedback themes, specificity of customer comments, and the contractor's responsiveness to concerns. We gave additional weight to detailed reviews that mentioned specific project types, communication quality, timeliness, and workmanship details. Years licensed through the CSLB provided insight into experience levels, though we recognized that newer contractors with strong review profiles can deliver excellent service. Our evaluation considered the total package: a contractor with decades of experience but inconsistent reviews ranked differently than a newer operation with consistently outstanding customer feedback and demonstrated project quality.

What to Look for in a Concord Concrete Contractor

When hiring a concrete contractor in Concord, California State License Board verification should be your first step. Every contractor must hold an active C-8 (Concrete) license or a broader A or B classification that includes concrete work. The CSLB website allows you to check license status, view complaint history, and verify bond and insurance information. Never hire an unlicensed contractor regardless of their quoted price—you forfeit legal protections and may face liability for injuries or substandard work.

Concord's climate presents specific challenges for concrete installation. Summer temperatures frequently exceed 90 degrees, which accelerates concrete curing and can lead to cracking if contractors don't implement proper hydration techniques and curing compounds. Winter work requires attention to forecasted rain, as precipitation during the curing period can compromise surface finish and structural integrity. Experienced local contractors understand these timing considerations and schedule pours accordingly. Additionally, Concord's soil conditions—particularly expansive clay in many areas—require proper excavation depth, base material selection, and compaction to prevent settling and cracking.

Contra Costa County requires permits for most concrete work, including driveways, patios, and structural elements. Your contractor should handle permit acquisition and understand local building codes regarding setbacks, drainage requirements, and ADA compliance where applicable. Ask potential contractors about their permitting experience and whether they'll manage inspections. Request detailed written estimates that specify concrete mix specifications (typically 3,000-4,000 PSI for residential work), reinforcement details (rebar or wire mesh), thickness measurements, and site preparation procedures. Quality contractors provide transparent timelines, discuss finish options, and explain their approach to control joints and expansion considerations.

Questions to Ask Before Hiring

Before signing a contract, verify the contractor's CSLB license number and check their status online. Ask for proof of workers' compensation insurance and general liability coverage, requesting certificates that list you as an additional insured for your project duration. Question their experience with projects similar to yours—a contractor specializing in decorative stamped concrete brings different expertise than one focused on commercial flatwork or structural foundations.

Discuss the concrete mix specifications they'll use and why they're appropriate for your project and Concord's climate. Ask about their approach to ground preparation, including excavation depth, base material type, and compaction methods. Understanding their quality control processes for weather-related scheduling, curing procedures, and finishing techniques helps you assess their professionalism. Request a detailed timeline with milestones and ask about their policy for delays due to weather or unforeseen site conditions.

Inquire about their warranty or guarantee on both materials and workmanship. While concrete naturally develops minor surface cracks over time, quality contractors stand behind their structural work and finishing. Ask for local references from recent projects and whether you can view completed work. Discuss payment terms—reputable contractors typically request a deposit (often 10-20%) with the balance due upon satisfactory completion, never full payment upfront. Finally, ensure all agreements, specifications, timelines, and costs are documented in a written contract before work begins.

License #1050256 • Concord, CA

7 years licensed Workers' Comp ✓ $25,000 bond Active License ✓

View Profile
Aloha Concrete And Design brings seven years of licensed experience to Concord's concrete market, operating under the leadership of project manager June, who customers consistently describe as responsive, professional, and communicative. With a perfect 5-star Google rating based on three reviews, they've demonstrated expertise in comprehensive residential projects including patios, driveways, front entrance walkways, and drainage solutions—indicating versatility beyond basic flatwork.

Their September 2025 review reveals capability with large-scope projects, as one customer described "a pretty big scope of work" covering multiple concrete elements plus drainage, with the team delivering quality results "from start to finish." This suggests Aloha Concrete And Design possesses the project management skills and crew capacity to handle complex residential installations that involve coordination of multiple concrete elements. The December 2025 review reinforcing June's responsiveness and professional communication, along with notes about thorough cleanup, indicates attention to the complete customer experience beyond just the concrete work itself.

#3

Cemcon

License #924461 • Concord, CA

17 years licensed Workers' Comp ✓ $25,000 bond Active License ✓
4.7
3 reviews
View Profile
Cemcon stands out with the most extensive licensing history in this comparison, holding an active California contractor license for 17 years since 2008. This longevity demonstrates sustained business operation through varying economic conditions and establishes them among Concord's most experienced concrete contractors. They maintain all required credentials including workers' compensation insurance and a $25,000 contractor bond, meeting California's legal requirements for contractor operation.

Their Google presence shows a 4.7-star rating based on three reviews, with limited recent feedback available for analysis. The December 2021 review noting "pretty good service is almost there" suggests competent work execution, though the phrasing indicates the reviewer perceived minor room for improvement in some aspect of service delivery. The lack of extensive recent reviews doesn't necessarily indicate service quality issues—many established contractors rely primarily on referral business and maintain lower online profiles while consistently serving their customer base.

Cemcon's nearly two decades of continuous licensing suggests they've successfully completed numerous projects throughout Concord and Contra Costa County, accumulating substantial experience with local soil conditions, permitting processes, and climate considerations that impact concrete work. Their longevity may appeal to homeowners who prioritize a contractor's established track record and sustained business presence over those seeking extensive recent online reviews. With their experience level, they likely handle a broad range of residential and commercial concrete applications. Homeowners considering Cemcon should request recent project references and examples of completed work to supplement the limited online review information, ensuring their capabilities align with specific project requirements.
#4

MCE Corporation

License #439295 • Concord, CA

43 years licensed Workers' Comp ✓ $25,000 bond Active License ✓
3.2
15 reviews
View Profile
MCE Corporation operates with the most extensive licensing history of any contractor in this comparison, maintaining an active California contractor license for 43 years since 1982. This exceptional longevity establishes them as one of Concord's longest-operating concrete contractors, with experience spanning multiple decades of construction practices, building code evolution, and regional development. They maintain full workers' compensation insurance and required bonding, meeting all California contractor legal requirements.

Their Google rating of 3.2 stars across 15 reviews presents a mixed customer feedback profile that requires careful consideration. Positive reviews from 2020 highlight helpful staff members and responsive service for municipal maintenance work, suggesting capability with public works and commercial projects. However, negative reviews cite concerns about work site management, dust control, and communication with nearby residents during street-level operations. One review appears misplaced (mentioning crab cakes, clearly intended for a restaurant), which sometimes occurs with Google business listings and should be disregarded when evaluating concrete services.

MCE Corporation's four-decade history and their work with municipal entities suggests expertise in commercial, public works, and large-scale concrete applications rather than primarily residential focus. Their experience may include street improvements, public infrastructure, and commercial development projects throughout Contra Costa County. Homeowners considering MCE Corporation should request residential project references specifically, as their operational focus and project management approach may differ from contractors who specialize in residential work. Their extensive experience could benefit large residential projects or those requiring specialized commercial-grade installations, though customers prioritizing personalized residential service and communication may find better alignment with contractors who focus exclusively on homeowner projects.

Priority Score

Our algorithm combines all factors into a single score, updated regularly.

Our comprehensive ranking methodology for Concord concrete contractors combines regulatory verification, customer feedback analysis, and business stability indicators to provide homeowners with reliable, actionable information. We began by searching the California State License Board database for all active C-8 (Concrete Contractor) licenses listing Concord as their primary business location. Each contractor's license status, issue date, bond amount, and workers' compensation insurance coverage underwent verification—only contractors meeting all legal requirements advanced to our detailed evaluation.

We collected review data from Google and Yelp, recognizing these platforms as the primary sources where homeowners research contractors and share experiences. Rather than relying solely on average star ratings, we analyzed review content for specific themes: communication quality, timeliness, workmanship, problem resolution, and professionalism. We assessed review recency, giving greater weight to feedback from 2024-2026 as it reflects current business operations. Review volume factored into our confidence level—contractors with 15-20 reviews provide more statistical reliability than those with only 2-3 reviews, though newer contractors with limited but consistently excellent feedback received appropriate consideration.

Years licensed through the CSLB provided context for experience levels, though we recognized that longevity alone doesn't guarantee quality—some long-established contractors may have inconsistent recent performance, while newer operations can deliver exceptional service. We examined the completeness of each contractor's business information, including website presence, contact accessibility, and professional presentation. All data was collected in January 2026, and we verified information across multiple sources to ensure accuracy. This multi-factor approach provides a more complete picture than any single metric, helping homeowners understand both the credentials and the customer experience each contractor delivers.

Frequently Asked Questions

How much does concrete cost in Concord?
Concrete costs in Concord typically range from $6 to $15 per square foot for basic installations, with decorative or specialty work reaching $15 to $30 per square foot or higher. A standard residential driveway averaging 400-600 square feet generally costs between $3,000 and $8,000 depending on thickness, reinforcement requirements, and site preparation complexity. Factors affecting Concord pricing include soil conditions requiring extra excavation or base preparation, particularly in areas with expansive clay soils common throughout Contra Costa County. Accessibility challenges, such as narrow side yards or properties requiring wheelbarrow concrete placement rather than truck access, increase labor costs. Premium finishes like stamped patterns, exposed aggregate, or colored concrete add $3-$8 per square foot to base pricing. Summer scheduling during peak construction season may command higher rates than winter work, though weather considerations make spring and fall optimal for concrete placement in Concord's climate. Always obtain detailed written estimates from multiple licensed contractors, ensuring quotes specify concrete strength (PSI), thickness, reinforcement type, and site preparation scope for accurate comparison.
Do I need a permit for concrete work in Concord?
Most concrete work in Concord requires permits issued by the City of Concord Building Division, which enforces California Building Code requirements and local ordinances. Driveways, patios exceeding certain sizes, walkways connecting to public sidewalks, and any structural concrete work typically require permits. Even replacement concrete often needs permitting to ensure proper drainage, setback compliance, and ADA accessibility where applicable. Your contractor should handle permit acquisition as part of their service, as they're responsible for ensuring work meets code requirements. Permit fees vary based on project valuation, and inspections occur at specific construction phases—typically after excavation and reinforcement placement but before concrete pouring, plus a final inspection after completion. Working without required permits can result in fines, mandatory removal of completed work, and complications when selling your property, as unpermitted work may appear in title reports. Contact Concord's Building Division at (925) 671-3351 or visit their office to verify permit requirements for your specific project before beginning work.
What should I ask a concrete contractor before hiring?
Start by requesting their California contractor license number and verify it through the CSLB website to confirm active status, check complaint history, and ensure proper bonding and insurance. Ask how long they've operated in Concord and request references from recent local projects similar to yours, including contact information so you can discuss their experience. Question their approach to site preparation—specifically excavation depth, base material type (crushed aggregate is standard), compaction methods, and how they address Concord's soil conditions. Discuss concrete specifications including PSI strength (3,000-4,000 PSI is typical for residential work), thickness appropriate for your application, and reinforcement method (rebar or wire mesh). Ask about their curing process and how they protect concrete during Concord's hot summers or rainy winters. Request a detailed written estimate specifying all materials, labor, timeline, and payment schedule—reputable contractors provide transparent documentation. Inquire about their warranty on workmanship and what it covers. Ask who will supervise your project daily and how they handle communication if issues arise. Question their policy on permits and inspections, ensuring they'll manage this process. Finally, discuss their cleanup procedures and what condition your property will be in upon project completion.
How do I verify a contractor's license in California?
Visit the California State License Board website at cslb.ca.gov and use their "License Search" tool, which provides free public access to contractor records. You can search by license number, business name, or contractor name. The results display current license status (Active, Inactive, Suspended, or Revoked), license classification (C-8 for concrete contractors), issue and expiration dates, bonding status, and workers' compensation insurance compliance. The detailed record shows any disciplinary actions, citations, or complaints filed against the contractor. Verify the business address matches what the contractor provided and check that their license has been active continuously rather than lapsing and reinstating. You can also call the CSLB's automated information line at 800-321-2752. Never hire contractors who claim they "don't need a license" for smaller jobs—California law requires licensing regardless of project size, and using unlicensed contractors eliminates your access to the Contractors State License Board's recovery fund if problems occur.
What's the best time of year for concrete work in Concord?
Spring (March through May) and fall (September through November) offer optimal conditions for concrete work in Concord, with moderate temperatures and lower precipitation probability. These seasons avoid summer's intense heat, which accelerates concrete curing and increases cracking risk if contractors don't implement proper hydration and curing techniques. They also avoid winter's higher rainfall, which can delay projects and potentially compromise concrete if precipitation occurs during the critical curing period. Summer work (June through August) is feasible with experienced contractors who understand hot-weather concrete placement—this requires morning pours before peak temperatures, evaporation retarders, and diligent moisture maintenance during curing. Winter projects (December through February) carry weather-related scheduling uncertainty, though Concord's mild winters allow work during dry periods between storms. Contractors typically monitor forecasts closely and may delay pours if rain threatens within 24-48 hours of placement. Spring scheduling should begin in late winter as contractors book up quickly for the prime season. Fall offers the advantage of contractors having more availability after summer's peak period while weather remains favorable for quality concrete placement and curing.
Selecting the right concrete contractor in Concord requires balancing verifiable credentials, demonstrated customer satisfaction, relevant experience, and alignment with your specific project needs. The four contractors profiled in this guide—Illice Concrete, Aloha Concrete And Design, Cemcon, and MCE Corporation—each bring different strengths, experience levels, and service approaches. Illice Concrete's exceptional recent customer feedback and communication emphasis appeal to homeowners prioritizing personalized service and responsiveness. Aloha Concrete And Design offers proven capability with comprehensive residential projects and professional project management. Cemcon provides 17 years of established presence in Concord's concrete market, while MCE Corporation's four decades of operation demonstrates sustained business longevity, particularly in commercial and municipal work.

No single contractor suits every project or homeowner. Your decision should consider project scope, timeline, budget, and personal priorities regarding communication style and service approach. Always verify license status through the CSLB, obtain multiple detailed written estimates, check references, and ensure contracts specify all work details before committing. Remember that the lowest bid rarely delivers the best value—quality concrete work requires proper materials, adequate site preparation, and skilled execution that prevents costly repairs down the road.

Compare Local Pros provides the factual information and verified data you need to make informed contractor selections, but the final decision rests with you. Take time to interview multiple contractors, ask detailed questions about their approach to your specific project, and trust your instincts about professionalism and communication quality. Request quotes from at least three licensed contractors to understand market rates and compare proposed approaches. Quality concrete work is an investment in your property that should last decades when properly installed—selecting a qualified, licensed contractor with proven customer satisfaction gives you the best opportunity for successful outcomes and long-term durability in Concord's unique climate and soil conditions.
