Mares & Dow Construction & Skylights Inc. provides professional new deck and porch construction in Hercules, CA, helping homeowners transform unused or underutilized outdoor areas into safe, functional, and long-lasting extensions of their home. With over 40 years of experience as a Bay Area general contractor, we specialize in building structurally sound outdoor spaces that are carefully designed to match each home’s architecture, layout, and long-term performance needs.
In Hercules, outdoor living improvements are a practical way to expand usable space without altering the home’s interior footprint. A properly built deck or front porch adds both functional square footage and architectural value, creating areas for relaxation, entertaining, and everyday use. However, these results depend heavily on correct planning, structural engineering, and high-quality construction practices.
Every project we complete is built with attention to load-bearing requirements, site conditions, and integration with the home’s existing foundation and exterior systems. We prioritize long-term durability over short-term appearance, ensuring that each deck or porch performs reliably through years of residential use and environmental exposure.
Homeowners choose Mares & Dow Construction & Skylights because they want a contractor who understands both the structural and design aspects of outdoor construction—delivering results that are safe, stable, and visually aligned with the home.

If you are considering a new deck or front porch in Hercules, CA, selecting the right contractor is the most important step in ensuring a successful build. These are not simple exterior upgrades—they are structural additions that must be properly engineered, securely anchored, and designed to integrate with your home’s existing framework.
Homeowners typically pursue deck and porch construction when they want to improve both the function and appearance of their property. In many cases, the goal is to create additional outdoor living space, improve access between indoor and outdoor areas, or upgrade outdated entryways that no longer provide adequate safety, usability, or visual appeal.
A professionally built deck can turn a basic backyard into a fully usable outdoor living environment suitable for dining, gatherings, or quiet relaxation. A new front porch can significantly improve curb appeal while also creating a more functional and protected entry point to the home. In both cases, proper planning and construction quality determine the long-term success of the structure.
At Mares & Dow Construction & Skylights, we manage the entire process from initial evaluation to final construction. This includes assessing site conditions such as slope, drainage, and soil behavior, as well as ensuring proper structural design and framing methods are used for each specific project. We also ensure that every build aligns with applicable building standards and long-term performance expectations.
Our focus is not only on building outdoor structures, but on building them correctly—so they remain safe, stable, and functional for years to come without premature wear or structural issues.

Homeowners in Hercules, CA choose Mares & Dow Construction & Skylights Inc. because they want new deck and porch construction that is built with structural precision, long-term durability, and proper integration into the home’s existing architecture. With more than 40 years of experience as a Bay Area general contractor, we understand how outdoor residential structures must be engineered to perform safely under daily use, environmental exposure, and long-term load conditions.
Unlike cosmetic exterior upgrades, decks and front porches are structural additions that rely on correct framing, secure attachment points, and properly designed load paths. In Hercules, where properties may include varying soil conditions, elevation changes, and exposure to seasonal moisture, these factors become even more important. Each project is carefully evaluated before construction begins to ensure the design is appropriate for the specific site conditions.
Our approach focuses on building outdoor structures that are not only visually consistent with the home but also engineered for stability and long-term performance. This includes proper foundation planning, accurate framing layout, and attention to how the new structure connects to existing exterior walls and support systems. These details help ensure the finished deck or porch remains secure, level, and functional over time.
We also prioritize design integration so that every deck or porch feels like a natural extension of the home rather than an added structure. This includes matching proportions, aligning with architectural features, and ensuring the finished build complements the home’s overall exterior style. The result is a cohesive structure that enhances both usability and curb appeal.
Clear communication and structured project planning are also key reasons homeowners trust our team. From initial consultation through completion, we provide a transparent process so homeowners understand the scope, construction approach, and expected outcome at every stage.

Mares & Dow Construction & Skylights Inc. provides complete new deck and front porch construction services in Hercules, CA, focused on building durable, structurally sound, and properly integrated outdoor living spaces. With over 40 years of experience as a Bay Area general contractor, we specialize in residential exterior construction that is engineered for long-term performance, safety, and architectural consistency.
Every project begins with a detailed understanding of the home’s layout, site conditions, and intended use of the outdoor space. Decks and porches are permanent structural additions, which means they must be carefully designed to account for load-bearing requirements, soil conditions, drainage patterns, and integration with the existing home structure. This ensures the finished build is stable, functional, and built to last.
We design and build custom residential decks in Hercules that expand usable outdoor living space for relaxation, dining, and entertaining. Each deck is planned according to the property’s layout and elevation to ensure proper structural support and long-term durability. The goal is to create a functional outdoor extension of the home that performs well under everyday residential use.
We construct new front porches that improve entryway functionality, enhance curb appeal, and create a defined transition between outdoor and indoor living areas. Each porch is designed to align with the home’s architectural style, ensuring proper proportions, structural balance, and long-term stability while improving everyday accessibility.
Proper framing is essential to the safety and longevity of any deck or porch. We build load-bearing structural systems that are designed to handle environmental exposure, daily use, and long-term weight distribution. This includes precise layout planning, secure connections, and correct structural spacing to ensure stability over time.
Safe and functional access is a critical part of every outdoor construction project. We design and build stairs and transition points that connect indoor and outdoor spaces with proper alignment, stability, and usability. Each access system is engineered to meet practical safety standards while maintaining design consistency.
A well-built deck or porch should feel like it belongs to the original home design. We carefully integrate all new structures with the home’s existing exterior materials, rooflines, and proportions to ensure a cohesive and visually balanced result. This helps maintain architectural harmony while improving functionality.

Mares & Dow Construction & Skylights Inc. provides new deck and porch construction services throughout Hercules, CA, serving homeowners across its residential neighborhoods and surrounding communities. Each area in Hercules has distinct site conditions, architectural styles, and lot layouts, which is why every project is carefully planned to ensure proper structural design, safe installation, and long-term performance.
As a Bay Area general contractor with decades of experience, we understand how local factors such as soil conditions, elevation changes, drainage flow, and home design influence outdoor construction. This allows us to build decks and porches that are not only structurally sound but also properly integrated into the surrounding environment and neighborhood character.
Victoria by the Bay is a newer residential community with modern homes and planned layouts. Many properties in this area benefit from custom backyard decks that expand usable living space and create defined outdoor areas for dining, relaxation, or entertaining. Construction in this neighborhood typically focuses on clean structural integration with newer architectural designs.
These established Hercules neighborhoods include a mix of home styles and layouts, making them well-suited for front porch construction projects. Many homeowners choose to upgrade or replace existing entryways to improve curb appeal and create a more functional and welcoming front entrance. Porch designs here are typically matched carefully to existing exterior finishes and rooflines.
Olympian Hills includes hillside properties where elevation changes and sloped lots are common. Deck construction in this area often requires elevated or reinforced structural systems to ensure stability and safe load distribution. Proper engineering is especially important in hillside conditions to maintain long-term structural integrity.
Refugio Valley is a family-oriented residential area where homeowners frequently invest in backyard deck construction to expand everyday living space. Decks in this neighborhood are often designed for practical use, including outdoor dining, seating areas, and direct access from interior living spaces.
Homes near the Hercules waterfront often require outdoor structures designed with additional environmental exposure considerations. Decks and porches in these areas are built to account for wind exposure and moisture conditions while maintaining structural durability and architectural consistency with the surrounding homes.
Across all Hercules neighborhoods, every deck and porch project is designed with attention to site-specific conditions, ensuring proper construction methods, safe structural performance, and long-term usability.

Even when planning a new deck or front porch in Hercules, CA, homeowners often encounter site and design challenges that must be addressed early in the construction process to ensure the structure is safe, stable, and properly integrated with the home. At Mares & Dow Construction & Skylights Inc., we evaluate these conditions before construction begins so the final build performs correctly over time and meets proper structural standards.
Because outdoor structures are directly exposed to soil movement, moisture, and environmental conditions, careful planning is essential. Without proper design and engineering, issues such as instability, drainage problems, or poor structural alignment can affect long-term performance. Our approach focuses on identifying and resolving these factors during the planning phase rather than after construction begins.
Many properties in Hercules include sloped or uneven terrain, which requires specialized structural planning for deck construction. We design elevated or reinforced framing systems that ensure the deck remains level, properly supported, and safe for long-term residential use regardless of grade changes.
Some homes have entryways that are too small or poorly configured for functional porch construction. We design new front porches that improve usability, create a defined entry space, and maintain proportional balance with the home’s exterior architecture.
Proper drainage is a critical factor in outdoor construction. Poor water management can lead to moisture buildup around support posts or foundation areas. We evaluate drainage patterns to ensure decks and porches are positioned and constructed to reduce exposure to standing water and long-term moisture-related issues.
A common issue in improperly built outdoor structures is weak or incorrect attachment to the home’s existing framing. We ensure that all new decks and porches are properly connected to the home’s structure using appropriate load-bearing methods to maintain stability and prevent future movement or separation.
Many homeowners have outdoor areas that are not being used effectively due to poor layout or outdated design. A properly planned deck or porch can convert these areas into functional living spaces that support daily use, relaxation, and outdoor activities while improving the home’s overall usability.
By addressing these conditions early, we ensure that every deck and porch project in Hercules is designed for long-term performance, safety, and structural reliability.

Before beginning any new deck or front porch construction in Hercules, CA, homeowners need to evaluate existing site conditions that may affect how the structure should be designed and built. Identifying these factors early helps ensure the new construction is properly planned, safely engineered, and suited to the specific conditions of the property.
At Mares & Dow Construction & Skylights Inc., we review each site carefully before construction begins so that potential challenges related to grading, drainage, or structural layout are addressed during the planning stage rather than during or after the build.
If your yard shows signs of uneven surfaces, soft soil areas, or visible shifting, these conditions may impact how a deck foundation or porch support system should be designed. Proper grading and structural planning help ensure the finished structure remains level and stable over time.
For front porch construction, the layout of your existing entryway is an important factor. Narrow access points, mismatched step heights, or limited landing space may indicate the need for a redesigned porch structure that improves both safety and usability.
Water flow is a key consideration in outdoor construction. If you notice pooling water, runoff near the foundation, or saturated soil around planned construction areas, these conditions should be evaluated before building begins to ensure long-term structural protection.
If your property currently has an older deck or porch, look for signs of wear such as movement, separation from the home, or uneven support. While our focus is new construction, understanding existing conditions helps guide proper replacement planning and structural improvements.
The most reliable way to ensure a successful deck or porch project is to have an experienced contractor evaluate your property. A professional assessment helps identify structural considerations, layout opportunities, and site-specific requirements that affect design and construction.
We take this step seriously on every project to ensure the structure is properly planned and built for long-term performance, safety, and usability.

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!
