Choosing the right contractor is one of the most important decisions you’ll make when planning a deck or porch project. A well-built outdoor structure must do far more than look attractive.

Our decades of experience throughout the Bay Area have given us a deep understanding of local construction practices, property layouts, environmental considerations, and homeowner expectations.

That’s exactly what our team provides.
Whether you’re starting from scratch with a brand-new deck or replacing an aging structure, we begin by understanding your goals. Some homeowners want a comfortable outdoor dining area.

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!

Many deck and porch issues begin as small problems that are easy to overlook. A loose railing, a cracked board, a soft spot underfoot, or minor settling may not seem urgent at first. Outdoor structures are constantly exposed to weather, moisture, temperature fluctuations, and everyday use. Over time, these seemingly minor concerns can develop into larger structural problems that affect safety, appearance, and long-term performance.
Knowing what to look for and how to respond can help homeowners protect their investment and avoid more extensive repairs in the future.
1. Don’t Ignore Warning Signs
One of the most common mistakes homeowners make is assuming visible wear is simply part of normal aging. While some weathering is expected, certain symptoms may indicate underlying structural concerns that require professional attention. If you notice any of these issues, it’s a good idea to schedule a professional evaluation before the condition worsens.
2. Evaluate the Extent of the Problem
Not every deck or porch issue requires complete replacement. In some situations, targeted repairs can restore safety and functionality while extending the life of the structure.
3. Address Water-Related Issues Quickly
Moisture is one of the leading causes of deck and porch deterioration. Water intrusion can weaken framing components, accelerate material breakdown, and reduce the lifespan of the structure.
4. Consider Whether the Space Still Meets Your Needs
Sometimes the issue isn’t structural damage but functionality. As families grow and lifestyles change, many homeowners find that their existing deck or porch no longer supports how they use the space.
5. Schedule a Professional Inspection
Because many structural issues develop beneath the surface, a professional evaluation can provide valuable insight into the condition of the structure.
6. Plan for Long-Term Value
If your deck or porch is showing signs of age, proactive planning often provides the best results. Addressing issues early may reduce repair costs, improve safety, and create opportunities to enhance the overall functionality and appearance of the space.
Whether you need repairs, an expansion, a complete replacement, or a custom-built outdoor living area, investing in quality construction can help improve both your lifestyle and your home’s value.
If you’ve noticed signs of wear, deterioration, or structural concerns, don’t wait for the problem to become more serious. Contact Mares & Dow Construction & Skylights today for a free estimate. Our experienced team can evaluate your deck or porch, explain your options, and help you determine the best path forward for your home.

The cost of building a deck or porch in Alamo depends on several factors, including the size of the project, the materials you choose, the design complexity, and any custom features you want to include. A small front porch will typically cost less than a large multi-level deck designed for entertaining. Material choices such as redwood, cedar, composite decking, hardwood, or PVC decking can also affect the overall investment. Features such as built-in seating, custom railings, covered areas, pergolas, and deck lighting may increase project costs as well. At Mares & Dow Construction & Skylights, we provide customized estimates based on your home's layout, your goals, and your budget so you can make an informed decision about your project.
The best decking material depends on what matters most to you. Redwood is a popular choice because of its natural beauty and classic appearance that complements many Bay Area homes. Cedar is another attractive option that offers warmth and character. Composite decking is often chosen by homeowners who want a durable, low-maintenance surface that doesn't require frequent staining or sealing. PVC decking is also a strong option for those looking for excellent moisture resistance and long-term durability. During your consultation, we can explain the benefits of each material and help you choose the option that best fits your lifestyle, maintenance preferences, and budget.
Every project is different, so the timeline depends on the size and complexity of the work. A smaller porch project may be completed faster than a large custom deck with multiple levels, stairs, railings, and covered areas. Permit approvals, material availability, weather conditions, and site preparation can also affect the schedule. At Mares & Dow Construction & Skylights, we provide realistic timelines and keep homeowners informed throughout the entire process. Our goal is to complete your project efficiently while maintaining the high-quality workmanship that has defined our company for over 40 years.
Composite decking and traditional wood decking both offer advantages. Composite decking is popular because it requires less maintenance and is designed to withstand years of weather exposure without the need for regular staining or sealing. Traditional wood decking, such as redwood or cedar, offers a natural appearance that many homeowners prefer. Wood provides timeless beauty and character, while composite materials offer convenience and durability. The right choice depends on your personal preferences, maintenance expectations, and long-term goals. We help homeowners compare options so they can select the material that best fits their needs.
In many cases, yes. If the structure of the deck is still in good condition, repairs may be all that's needed to restore safety and appearance. Common repairs include replacing damaged boards, strengthening support components, repairing stairs, upgrading railings, or addressing isolated areas of deterioration. If the deck has extensive structural damage or has reached the end of its lifespan, replacement may be the better long-term solution. Our team carefully evaluates each structure and provides honest recommendations based on its condition, helping homeowners choose the most practical option.
A custom deck or porch can include a wide range of features designed to improve comfort, functionality, and appearance. Popular additions include covered porches, pergolas, decorative railings, built-in seating, expanded stairways, outdoor dining areas, entertainment spaces, and multi-level deck designs. Some homeowners also choose low-maintenance decking materials, privacy features, or waterproof deck systems to increase usability. The goal is to create an outdoor space that matches your lifestyle and complements your home. We work closely with homeowners to design spaces that are both beautiful and practical.
A professionally built deck or porch can add value to your home by increasing usable outdoor living space and improving curb appeal. Many buyers appreciate outdoor areas where they can relax, entertain guests, or spend time with family. In addition to potential resale benefits, homeowners often enjoy the immediate value of having a more functional and attractive outdoor space. Whether you're planning to stay in your home for years or eventually sell, a quality deck or porch can be a worthwhile investment that enhances both everyday living and long-term property value.
Deck and porch construction involves much more than simply installing boards and railings. Proper planning, structural support, material selection, and construction techniques are essential for safety and long-term durability.

Hiring a professional also helps reduce the risk of costly mistakes and ensures the project is completed correctly.
