Mares & Dow Construction & Skylights. We offer a comprehensive retaining wall service for homeowners and businesses in and around Concord. Retaining walls are a versatile landscaping feature that can transform your yard, frontage, or land, enabling you to enjoy areas of flat ground rather than a continuous slope. We provide a wide range of professional retaining wall construction solutions, using cutting-edge materials and innovative designs to deliver eye-catching walls that are highly functional and built to last.
As well as traditional concrete walls and wooden retaining walls, we also offer an exciting selection of block systems, which click together to form tough, durable walling that can also be shaped exactly as you wish. Systems such as Versa Lok, Tensar, Calstone, and Keystone can be built to form curves, taper, or bend, enabling customers to get the look that they want without compromising the wall’s performance.
Over time, even well-built walls will begin to degenerate, often as a result of weathering. We can repair many different types of retaining walls, shoring them up so that they’re capable of giving years more useful service. We can also undertake remedial and improvement work on existing walls, ensuring they are safe and have a reliable drainage system in place. No matter what the problem is with your retaining wall, we can normally take care of it for you.

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!

Retaining walls are more than just landscape features — they protect your property from erosion, improve usable outdoor space, and enhance curb appeal. Whether you’re dealing with a steep slope or want to upgrade your yard, understanding the basics can help you make informed decisions. Below are common questions homeowners in Concord and the surrounding East Bay area ask before starting a retaining wall project.
A retaining wall is a structure designed to hold back soil and prevent erosion on sloped land. In Concord's varied terrain, walls can create level areas for lawns, patios, or driveways while preventing soil movement that can damage landscaping or foundations.
Contractors in the Bay Area commonly work with materials like pressure-treated wood, redwood, concrete, cinder blocks, and modern interlocking systems such as Versa-Lok, Pavestone, and Rockwood, allowing you to choose based on durability and aesthetic preferences.
Costs can vary widely based on size, materials, design complexity, and site conditions. On average, smaller residential walls in Concord might range from roughly $860 to $6,453 or more, not including permits or engineering fees.
Yes — many retaining walls, especially those over a certain height or carrying significant load, require building permits and may need engineered plans to comply with local codes. Proper permitting protects you legally and ensures the wall meets safety standards.
Without effective drainage, water can build up behind the wall, increasing pressure and leading to cracking or failure. Features like gravel backfill, drain pipes, and weep holes are essential in the Concord climate to extend the wall’s lifespan.
With quality materials and proper installation — including drainage and correct structural design — retaining walls can last for decades. Professional contractors build for longevity and performance under local weather and soil conditions.
Yes — experienced contractors can often repair weakened or damaged walls before problems worsen, saving you the cost of full replacement. Early intervention is key to preventing bigger structural issues.
Look for a contractor with local experience, proper licensing, solid references, and familiarity with Bay Area soils and building codes. Ask for multiple quotes and ensure the contractor plans for drainage, structural integrity, and long-term performance.
