Mares & Dow Construction & Skylights, Inc. provides professional deck and porch construction services throughout Lafayette, CA, with a deep understanding of the city’s terrain, architectural styles, and residential character. From hillside properties with scenic views to established suburban neighborhoods, we design and build outdoor structures that fit seamlessly into the environment and enhance how homeowners use their space.
Lafayette is known for its mix of mature neighborhoods, custom homes, and hillside properties—each requiring thoughtful planning when it comes to outdoor construction. Our team adapts every deck and porch design to suit the land, elevation changes, drainage conditions, and structural requirements specific to each property.
We proudly serve all major Lafayette neighborhoods, including:
Happy Valley – A highly sought-after residential area known for spacious lots and custom homes. We frequently design multi-level decks and expanded outdoor living spaces here to take advantage of larger property footprints and private settings.
With its rolling hills and scenic surroundings, this area often requires engineered deck systems and elevated porch structures designed for slope stability and long-term safety.
A well-established neighborhood where many homeowners choose front porch upgrades and backyard deck additions to modernize older homes while preserving their original charm.
A family-friendly area where backyard decks are often designed for everyday use, entertaining, and seamless indoor-outdoor living transitions.
A blend of historic and modern homes where porch enhancements and compact deck designs help maximize limited outdoor space without compromising style.
Known for its quiet residential streets and custom properties, this area often benefits from tailored porch designs and large-scale deck builds that complement hillside views.
We also serve properties near key local landmarks such as the Lafayette Reservoir and surrounding open space areas, where outdoor living structures often need to balance aesthetics with environmental and structural considerations.

Over time, decks and porches naturally experience wear due to weather, moisture, and soil movement. We specialize in diagnosing and correcting both visible and hidden structural issues.
Common problems include wood rot, moisture damage, and weakened framing components that compromise structural safety. We repair or rebuild affected areas using durable materials designed for long-term resistance.
We also fix unstable railings, stairs, and connections caused by shifting foundations or aging fasteners.
Foundation movement is common in hillside areas, leading to uneven surfaces or structural stress. We correct these issues by reinforcing footings and improving load distribution.
Older structures often require upgrades to meet current building codes, especially in regard to safety and seismic standards.
We also handle surface wear, including cracked boards and weather damage, as well as drainage problems that lead to moisture buildup and long-term deterioration.
If you notice early signs of damage, scheduling an evaluation is the best way to prevent larger structural issues.

Small issues can quickly become major structural concerns if ignored. Early detection helps prevent costly repairs and ensures safety.
Watch for signs such as uneven flooring, loose railings, cracked boards, or shifting support posts. These often indicate deeper structural problems.
Moisture damage, mold, or drainage issues can weaken key components over time if not addressed properly.
In hillside areas, movement in the structure or foundation should be evaluated immediately.
While minor maintenance can help preserve your deck or porch, structural issues should always be assessed by professionals.
If you notice warning signs, scheduling an inspection early can prevent more extensive damage.
Don’t wait for small problems to become major repairs. Reach out to our team today for professional guidance and a customized solution for your home.
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!

The timeline for a deck or porch project depends on several factors, including the size of the structure, the complexity of the design, and site conditions. Smaller projects may be completed within a couple of weeks, while larger or more customized outdoor living spaces can take several weeks from start to finish.
At Mares & Dow Construction & Skylights, we carefully plan every phase of construction to keep projects moving efficiently while maintaining the quality and attention to detail that have defined our work for more than 40 years.
Absolutely.
Sometimes repairs are sufficient, but if the structure has extensive rot, foundation problems, outdated framing, or safety concerns, replacement may be the better long-term investment.
Our team can evaluate the condition of your existing structure and provide honest recommendations based on what will offer the greatest safety, longevity, and value for your home.
Yes.

Maintenance requirements depend largely on the materials used.
Traditional wood decks generally require periodic staining, sealing, and inspections to protect against moisture and weathering. Composite materials typically require less maintenance and offer excellent durability.
Regardless of material, we recommend periodic inspections to identify any early signs of wear, loose hardware, drainage issues, or moisture intrusion before they become more serious problems.
Yes.
Dry rot and moisture damage are common issues in aging outdoor structures. Left untreated, these problems can compromise support beams, posts, joists, and framing components.
Our experienced team can identify the source of the problem, replace damaged materials, improve drainage, and restore the structure to safe operating condition. In some cases, a complete rebuild may provide the most cost-effective long-term solution.
A professionally built deck or porch can significantly enhance both the usability and curb appeal of your property. Outdoor living spaces are highly desirable among today's homeowners and can make a home more attractive to future buyers.
Beyond financial value, many homeowners find that investing in their outdoor spaces improves their everyday quality of life by creating comfortable areas for entertaining, relaxing, and spending time with family and friends.
