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!

Norma B. San Francisco, California

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!

Aaron R. Concord, California

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!

Myla L. Concord, California

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

Chris W. Walnut Creek, California

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!

Frequently Asked Questions About Skylight Installation in Alamo, CA

Skylights are a smart upgrade for homeowners in Alamo, CA, looking to enhance natural light, improve ventilation, and increase overall home value. With Alamo’s mix of custom homes, sloped roofs, and scenic surroundings, professional skylight installation is essential to ensure durability, energy efficiency, and code compliance. Below are answers to the most common questions homeowners ask when hiring a trusted skylight contractor in Alamo.

Homes in Alamo often benefit from fixed skylights, venting skylights, solar-powered skylights, and sun tunnels depending on room size and roof design. Fixed skylights are ideal for living rooms and stairwells, while venting skylights work well in kitchens and bathrooms to improve airflow. Sun tunnels are perfect for interior spaces with limited roof access. Each option can be customized to match Alamo’s upscale residential architecture.

The cost of skylight installation in Alamo typically depends on skylight type, size, roof pitch, and whether structural modifications are required. On average, homeowners can expect prices to start around $1,500 and range upward to $3,500 or more per skylight, especially for premium or motorized units. A professional on-site inspection ensures accurate pricing and long-term performance.

Yes. Modern skylights with Low-E glass, UV protection, and insulated glazing help regulate indoor temperatures and reduce energy costs. Proper installation ensures minimal heat loss in cooler months and prevents excess heat gain during warmer seasons, making skylights an energy-efficient addition for Alamo’s climate.

Skylights can significantly enhance a home’s appeal by making interiors brighter, more open, and visually attractive. In Alamo’s competitive real estate market, professionally installed skylights are often viewed as a premium feature that can improve resale value and attract discerning buyers.

Most standard skylight installations in Alamo can be completed in one day. More complex projects—such as custom skylights, multiple installations, or roof structural adjustments—may take longer. A qualified skylight contractor will coordinate timelines based on roof conditions and weather to minimize disruption.

Yes. Skylight installation typically requires a building permit to ensure compliance with local building and energy codes. A professional skylight contractor will handle the permitting process and schedule inspections, ensuring your project meets all Alamo and Contra Costa County regulations.

Routine maintenance includes checking seals, flashing, and glass for signs of wear or debris buildup. Annual inspections—especially after heavy rain or wind—help prevent leaks and extend the skylight’s lifespan. Venting skylights may also need occasional track and motor inspections to maintain smooth operation.

Look for a licensed, insured skylight contractor with experience working on Alamo homes and roof styles. Strong local reviews, manufacturer certifications, clear communication, and warranty coverage are key indicators of quality workmanship. Choosing a contractor familiar with local codes ensures a safe, durable, and energy-efficient installation.
