We provide full-service outdoor construction solutions designed to improve both the function and appearance of your home. Whether you’re starting fresh or upgrading an existing structure, our work is tailored to fit your property, lifestyle, and long-term goals.
We design and build custom wood and composite decks that are carefully matched to your home’s architecture and outdoor environment. Every deck is engineered for stability, usability, and visual harmony, whether it’s a compact urban build or a larger multi-level outdoor living space.
From welcoming front porches that enhance curb appeal to covered outdoor living areas built for year-round comfort, we create functional spaces that connect indoor and outdoor living. Each porch is designed with durability, comfort, and architectural consistency in mind.
Older or damaged decks often require more than surface-level fixes. We assess structural integrity, repair unsafe framing, reinforce weakened support systems, and bring existing decks up to current safety standards. This ensures your outdoor space remains secure and code-compliant.
We integrate practical and lifestyle-focused features that elevate how you use your outdoor space, including:
These enhancements are designed to make your deck or porch more functional, comfortable, and enjoyable year-round.
When repairs are no longer sufficient or cost-effective, we provide full deck removal and replacement services. This includes safe demolition of the existing structure, evaluation of the underlying support system, and construction of a new, stronger, and longer-lasting deck built to modern standards.
Each replacement project is an opportunity to improve safety, upgrade materials, and enhance the overall value and usability of your outdoor space.
We proudly serve homeowners throughout San Francisco, delivering custom deck and porch construction that fits the unique character, terrain, and architecture of each neighborhood.

Each neighborhood requires a tailored approach to layout, structure, and materials. From hillside engineering to compact urban design, we ensure every deck or porch is built to match both the property and the way homeowners want to use their space.
We also serve surrounding Bay Area communities for larger or specialized deck and porch construction projects, bringing the same level of craftsmanship and structural expertise beyond city limits.
San Francisco homes present unique construction challenges that require more than standard building practices. From steep hillsides and compact lots to aging structures and coastal weather, outdoor living spaces must be carefully designed and constructed to remain safe, functional, and durable for years to come. At Mares & Dow Construction & Skylights, we have decades of experience solving these challenges through thoughtful planning, quality craftsmanship, and structurally sound construction techniques.
Whether you’re building a new deck, replacing an aging porch, or repairing an existing structure, we begin every project with a comprehensive assessment of your property. By identifying structural concerns, environmental risks, and design limitations early, we can recommend solutions that improve safety, maximize usable space, and ensure lasting performance.
Many older decks were built decades ago using construction methods or materials that no longer meet today’s building standards. We inspect framing, beams, joists, posts, and connections to identify structural weaknesses before recommending repairs, reinforcement, or complete replacement when necessary.
San Francisco’s coastal climate exposes outdoor structures to frequent moisture, fog, and seasonal rain. Over time, these conditions can lead to wood rot, mold, deteriorated framing, and weakened structural components. We remove damaged materials, correct moisture-related issues, and rebuild affected areas using durable materials designed for long-term performance.
Many Bay Area properties are built on hillsides or uneven terrain, creating additional engineering requirements for decks and porches. We design and construct secure support systems, foundations, and framing that provide stability while making the most of your available outdoor space.
Smaller city lots often require creative planning to maximize functionality without overwhelming the property. We develop customized deck and porch layouts that improve traffic flow, create comfortable gathering areas, and make efficient use of every square foot available.
Older railings, stairs, and entryways may no longer meet current safety standards or building code requirements. We replace outdated components with sturdy, code-compliant systems that improve accessibility, enhance safety, and complement the overall appearance of your outdoor living space.
Because the Bay Area is located in an active seismic region, structural integrity is always a priority. We incorporate seismic-conscious construction practices that strengthen decks, porches, and elevated structures while helping them meet current building code requirements.
Constant exposure to sun, coastal air, humidity, temperature changes, and seasonal storms gradually wears down outdoor structures. We build with weather-resistant materials and proven construction methods that help protect your investment against the elements and reduce future maintenance needs.
Every successful project starts with understanding the condition of the existing structure. Before construction begins, we perform a detailed inspection to identify visible damage as well as hidden structural issues that could affect safety, longevity, or project scope. This proactive approach allows us to address potential problems before they become costly repairs.
At Mares & Dow Construction & Skylights, our goal is to deliver decks and porches that are not only visually appealing but also structurally sound, fully code-compliant, and built to withstand San Francisco’s demanding environment. Through careful planning, durable materials, and skilled craftsmanship, we create outdoor spaces homeowners can enjoy with confidence for many years to come.
Quality and service come first. We approach every job, big or small, with the same care and attention to detail we’d give our own homes. Our team combines time-tested building practices with modern innovation to deliver results that stand the test of time.

Backed by over 40 years of construction experience across the Bay Area, we understand what it takes to build decks and porches that not only enhance your home but also withstand the region’s unique environmental and structural challenges.
San Francisco is unlike most places to build. Hillside properties, compact urban lots, aging homes, strict building regulations, seismic considerations, and coastal weather all require careful planning and experienced craftsmanship. Our team has completed projects under these conditions for decades, giving homeowners confidence that their investment is being handled by professionals who understand the local landscape.
Every project is approached with the same commitment to quality, whether we’re repairing a weathered front porch, replacing an aging deck, or constructing a completely new outdoor living area. We believe successful construction starts long before the first board is installed. It begins with listening to your goals, evaluating the property carefully, developing practical solutions, and maintaining open communication from start to finish.
Rather than offering one-size-fits-all solutions, we tailor every project to your home’s architecture, property layout, lifestyle, and budget. Our goal is to create outdoor spaces that are as functional and durable as they are visually appealing, adding lasting value to your property while giving you more ways to enjoy your home.
We believe quality begins with the structure itself. Every deck and porch is built with careful attention to engineering, structural integrity, and long-term durability. We never cut corners or rely on temporary fixes. Instead, we use proven construction methods and quality materials that deliver dependable performance for years to come.
Home improvement projects should never leave homeowners guessing. We provide clear recommendations, realistic timelines, transparent pricing, and regular project updates so you always know where your project stands. Our team is available to answer questions, explain options, and help you make informed decisions throughout the construction process.
Our focus is never just on completing a project quickly. We design and build decks and porches that continue performing well long after construction is complete. Every recommendation we make considers long-term durability, maintenance requirements, structural safety, and how your outdoor space will be used in everyday life.
Exceptional craftsmanship is found in the details. From site preparation and structural framing to railings, stairs, decking installation, and finishing work, every stage of construction is completed with precision and care. This attention to detail helps ensure a finished product that is safe, attractive, and built to last.
Whether you’re updating a small front porch to improve curb appeal or creating a spacious backyard deck for entertaining family and friends, we bring the same level of professionalism, accountability, and craftsmanship to every project. Our reputation has been built one project at a time by delivering reliable service, durable construction, and outdoor living spaces that homeowners can enjoy with confidence for many years.
When you choose Mares & Dow Construction & Skylights Inc., you’re partnering with a local contractor that understands San Francisco, values quality workmanship, and is committed to building outdoor spaces that serve your family well for decades to come.
Planning a new deck or porch is an exciting opportunity to improve your home’s comfort, functionality, and value. Whether you’re replacing an aging structure or creating a brand-new outdoor living space, taking the time to plan carefully can make the entire process smoother and more successful.
In San Francisco, deck and porch projects often involve additional considerations such as hillside properties, limited lot sizes, coastal weather, seismic requirements, and local regulations. Addressing these factors early allows you to make informed decisions, avoid unnecessary delays, and build an outdoor space that performs well for years to come.
Before construction begins, it’s helpful to think beyond the appearance of the finished project. Consider how your family will use the space, how much maintenance you’re comfortable with, and what features will provide the greatest long-term value. A well-planned project not only looks beautiful on completion but continues to serve your needs for many years.
Start by identifying the primary purpose of your new deck or porch. Will it be a place for entertaining guests, relaxing after work, outdoor dining, family gatherings, gardening, or a combination of several activities? Understanding how you intend to use the space helps determine the ideal size, layout, seating areas, traffic flow, lighting, and other functional features.
If you already have a deck or porch, have it carefully evaluated before deciding whether repairs or replacement is the best option. Older structures may have hidden issues such as wood rot, deteriorated framing, loose railings, foundation movement, or outdated construction methods that no longer meet current building codes. Identifying these concerns early helps prevent surprises once construction begins.
Different decking and porch materials offer varying levels of durability, appearance, and maintenance. Natural wood provides timeless beauty but requires periodic sealing and maintenance, while composite decking offers excellent durability with reduced upkeep. Railings, stair materials, finishes, and hardware should also be selected based on your desired appearance, budget, and long-term maintenance expectations.
A deck or porch should feel like a natural extension of your home rather than an afterthought. Consider how the design complements your home’s architectural style, existing exterior finishes, landscaping, and overall curb appeal. Thoughtful planning creates a cohesive outdoor living area that enhances both functionality and property value.
Every property presents unique construction considerations. Sloped lots, elevated decks, drainage requirements, soil conditions, utility locations, and access limitations can all influence design and construction methods. Evaluating these conditions early helps ensure the finished structure is safe, stable, and engineered for long-term performance.
Most deck and porch projects in San Francisco require compliance with local building codes and, in many cases, inspections. Understanding these requirements before construction begins helps prevent costly delays, redesigns, or compliance issues later in the project.
Having a clear budget helps guide important decisions regarding materials, size, design features, and construction options. A well-planned budget also allows room for any structural improvements or site conditions that may be discovered during the planning phase, reducing the likelihood of unexpected costs.
One of the most valuable steps you can take is meeting with an experienced deck and porch contractor early in the planning process. A professional consultation provides an opportunity to discuss your ideas, evaluate the property, review structural considerations, explore material options, estimate project costs, and develop a realistic construction timeline. Receiving expert guidance early often leads to better design decisions and a more efficient project overall.
By taking these steps before construction begins, you’ll be better prepared to create an outdoor living space that fits your lifestyle, complements your home, and provides lasting value. Careful planning, thoughtful design, and experienced craftsmanship are the foundation of every successful deck and porch project, ensuring your investment remains safe, functional, and enjoyable for many years to come.

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!
