One of the challenges that many of our customers have is finding foundation repair contractors that actually specialize in foundations! Although we manage a variety of other remodeling, renovation, and refurbishment projects, we can also offer more than three decades of experience in successfully resolving foundation problems of many different types. If you’ve noticed the tell-tale signs that your foundations could be in need of some work, we can complete the entire project for you, promptly, professionally, and with great results.
When they discover that there is a problem with their foundations, many property owners may feel that a costly total replacement is the only option. We disagree! Why not let our expert team of seasoned foundation repair professionals complete an assessment of the issue and come up with some no-obligation options to resolve the problems you’re experiencing? In many cases, waterproofing or the installation of a retaining wall is all that’s needed to resolve your foundation problems – why pay for an entire replacement if you don’t need it?
Many of the products we use are sourced from the Grip-Tite range; experts in foundation solutions, Grip-Tite offers a dependable answer to many foundation repair problems. As certified Grip-Tite installers, we have the necessary skills and knowledge to install one of their systems exactly as required.
Because we work on local properties, we have a good knowledge of the nearby geology, drainage issues, and potential problems that earthquakes can cause here. This allows us to suggest foundation repairs we know are suitable and that we expect to result in firm, dependable foundations that will last a lifetime.

Mares & Dow Construction & Skylights installed a large Velux skylight for me in August 2017. The entire experience was wonderful and the skylight is beautiful, both functionally and aesthetically. Janet made sure the work was scheduled to be completed before a trip I had planned. Jimmy measured carefully when he quoted the work and even accommodated a last minute change on the location when he arrived to do the work. They protected my new floors and were careful to keep dust to a minimum. Archie came by to ensure that all was going smoothly. Freddy helped matched the stain on my nearly 70 year old tongue and grove ceiling that really took some effort and he even matched some a few small spots that a previous contractor had sanded and removed the original stain. EVERYONE was cheerful and knowledgeable. Now, my little mid century house has emerged into the light!
Mares & Dow Construction & Skylights replaced two aging skylights in our bedroom and installed automatic blinds on four skylights. This was not an easy job, since our bedroom has very very high cathedral ceilings. In fact, one other skylight installer refused to do the job altogether, and a second made a bid that was almost twice as expensive as Mares & Dow Construction & Skylights. Janet Mares, who was our main contact for the job, was a pleasure to work with. Her son, Jimmy, who led the installation, was fearless climbing the ceiling, and he eally knew his stuff. We’re thrilled with our new and improved skylights, and we appreciate Mares & Dow Construction & Skylights’ solid, reasonably priced, work. Thanks guys!
I’ve had Mares & Dow Construction & Skylights install 3 sun tunnels in my home and most recently, 2 skylights in my garage/art studio. I couldn’t be more satisfied with the quality of their work and professionalism! All my communications with their office and installers have been extremely pleasant. I would use them again (and again) and highly recommend them to anyone looking to install Velux skylights/sun tunnels in their home!
Being a new homeowner, i really did my research before having someone come out and give me a quote on a skylight. You never know what to believe when you read yelp reviews. So, i went ahead and had Jimmy from mares and dow come out and give me an estimate. He was right on time, came out and measured and was very professional while he was here. Janet called me a few days later and sent me over an estimate. I went them them and couldn’t be happier. It arrived in the time frame she had told me, and they were out that week. The workers came out on time, and were very friendly and professional. Dennis ( one of the owners) came out as well and checked on the job. The went above and beyond with their work. The skylight looks beautiful! Night and day from the old one. If you are wanting a skylight, i strongly reccomend going with mare and dow
We had Mares & Dow Construction & Skylights install a Velux skylight in our new master bathroom. The space was small and dark, so Mares & Dow Construction & Skylights suggested a big skylight to add in lots of natural light. They built in a double crown molding to beautifully frame the skylight, and now the space is open and airy with wonderful natural light. We can open the skylight during warm months to let in fresh air. It was a superb addition to our bathroom renovation and a great suggestion from Mares & Dow Construction & Skylights. They did a fantastic job and were great to work with! Thanks guys!

Homes in El Cerrito, CA, face foundation challenges due to hillside construction, expansive clay soils, coastal moisture, and frequent Bay Area seismic activity. Over time, these conditions can lead to cracking, settlement, and structural movement. Mares & Dow Construction & Skylights provides professional concrete foundation repair services in El Cerrito to help homeowners protect their homes and maintain long-term stability.
El Cerrito homeowners commonly notice cracks in concrete slabs or interior walls, sloping or uneven floors, sticking doors or windows, gaps around window and door frames, and separation between walls and ceilings. These signs often indicate foundation movement related to soil shifting and hillside conditions.
Our process begins with a detailed foundation inspection, evaluating soil conditions, slope stability, drainage, and structural integrity. Based on our findings, repairs may include foundation pier installation, slab leveling, crack injection, or structural reinforcement, customized for El Cerrito’s hillside and soil conditions.
El Cerrito has steep terrain and clay-rich soils that expand and contract with moisture changes. Combined with heavy winter rains and seismic activity, these factors place continuous stress on concrete foundations, making professional repair essential.
Yes. Many foundation issues in El Cerrito are worsened by poor drainage or hillside runoff. Along with structural repairs, we often recommend grading corrections, drainage improvements, and waterproofing solutions to reduce moisture-related foundation movement.
Minor repairs such as crack stabilization may take one to two days, while more extensive projects like pier installation or foundation leveling may take several days to a week, depending on slope access and site conditions. Clear timelines are provided before work begins.
Costs vary based on the extent of damage, foundation type, slope accessibility, and repair method. We provide transparent, detailed estimates so El Cerrito homeowners understand the scope of work and associated costs upfront.
In most cases, yes. Our experienced crews plan repairs to minimize disruption, allowing homeowners to remain in their homes during the process. Certain areas may be temporarily restricted for safety during active work.
Mares & Dow Construction & Skylights brings local expertise, certified professionals, and extensive experience with El Cerrito’s hillside, soil, and seismic conditions. We follow California building codes, use proven repair methods, and stand behind our workmanship for long-lasting results.
