Key Takeaways Homeowners must do their homework, and ask their contractors the right questions to confirm that they’re not working with someone who’s inexperienced, unlicensed…
A well-designed deck or porch does more than add square footage to your property—it transforms how you experience your home. Whether you envision a spacious backyard deck for entertaining, a welcoming front porch that enhances curb appeal, or a custom outdoor living area where your family can relax year-round, investing in professional deck and porch construction is one of the most effective ways to improve both functionality and value.
At Mares & Dow Construction & Skylights, Inc., we have been helping Bay Area homeowners improve their homes since 1983. With more than 40 years of experience in residential construction, remodeling, structural improvements, and outdoor living projects, our team understands what it takes to build outdoor spaces that are beautiful, durable, and designed for long-term performance.
Piedmont homeowners take pride in their properties. The city is known for its distinctive architecture, mature landscaping, and beautiful residential neighborhoods. Every deck or porch we build is thoughtfully designed to complement the character of the home while providing practical benefits that homeowners can enjoy every day.
Whether you’re building a brand-new deck, replacing an aging structure, adding a front porch, or creating a multi-level outdoor entertainment area, our experienced team delivers customized solutions tailored to your goals, budget, and property conditions.
Unlike temporary outdoor upgrades, a professionally built deck or porch becomes a permanent extension of your home. It creates a place for family gatherings, outdoor dining, relaxation, and entertaining while improving the overall appearance and usability of your property.
As a licensed General Contractor and Electrical Contractor (License #618118), we provide complete design-build services, managing every phase of construction from planning through final completion. Our goal is simple: deliver quality workmanship, honest communication, and outdoor spaces that stand the test of time.

Choosing the right deck and porch contractor can make all the difference in the success of your project. While decks and porches may appear straightforward, quality construction requires extensive planning, engineering, craftsmanship, and knowledge of local building requirements.
A deck must safely support people, furniture, outdoor kitchens, planters, and everyday use. A porch must integrate seamlessly with the home’s architecture while maintaining structural integrity and weather resistance. Every detail matters, from foundation support and framing to drainage, materials, railings, and finishing touches.
At Mares & Dow Construction & Skylights, we approach every project with a commitment to quality and long-term performance. Our process begins by listening to your goals and understanding how you want to use your outdoor space.
Some homeowners want a quiet retreat where they can enjoy Piedmont’s beautiful weather. Others envision an entertainment area for hosting family and friends. Some need to replace an aging deck that has developed structural issues, while others are adding outdoor living space to increase property value and improve daily enjoyment.
No matter the goal, our team develops customized solutions that balance aesthetics, functionality, durability, and budget.
We build:
Piedmont’s varied terrain often presents unique opportunities and challenges. Sloped lots, mature trees, historic homes, and elevation changes require thoughtful planning and experienced construction techniques. Our decades of Bay Area construction experience allow us to design and build structures that maximize outdoor enjoyment while respecting the character of the property.
We also simplify the process by handling inspections, project coordination, and construction management. Homeowners benefit from having a single experienced team overseeing every aspect of the project.
Whether you’re planning a new deck, a porch addition, or a complete outdoor transformation, our team is ready to help.

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!
