In Pleasant Hill, decks and porches are constantly exposed to sun, seasonal moisture, shifting soil conditions, and everyday wear from regular use. Over time, even well-built structures can develop issues that affect both safety and appearance.
At Mares & Dow Construction & Skylights, we frequently inspect, repair, and rebuild outdoor structures that have started to show signs of age, movement, or structural failure. With over 40 years of general contracting experience in the Bay Area, we know how to identify not just surface-level damage, but the underlying structural problems that cause it.
Here are some of the most common deck and porch issues we fix for Pleasant Hill homeowners:
Many homeowners don’t realize that deck issues often begin underneath the surface. What looks like minor cosmetic wear can actually be a sign of deeper structural weakening. That’s why we take a comprehensive approach, evaluating the framing, support posts, footings, and connections before recommending repair or replacement.
Our goal is always to restore safety first, then improve durability and appearance so your outdoor space can continue to be enjoyed with confidence.
If you’ve noticed any of these warning signs at your property, it’s important to act early. Addressing issues promptly can prevent more extensive damage and more costly reconstruction later.

If your deck or porch in Pleasant Hill is starting to show signs of wear, shifting, or surface damage, it’s important to take it seriously early. Outdoor structures in the Bay Area are constantly exposed to sun, seasonal moisture, and natural ground movement, so even small issues can quickly develop into larger structural concerns if they’re ignored.
The key is not to wait until the damage becomes obvious or unsafe. Instead, treat early warning signs as an opportunity to protect your home, your investment, and your safety.
Even if the deck still feels “usable,” these symptoms often point to underlying structural stress that should be evaluated by a professional contractor.
At Mares & Dow Construction & Skylights, we evaluate both visible and underlying structural conditions to ensure your outdoor space is safe, stable, and built to last. With over 40 years of construction experience in the Bay Area, we understand how local weather and soil conditions impact long-term performance.

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!

Building a new deck or porch is an excellent way to enhance your outdoor living space, improve your home’s curb appeal, and create an area for relaxing or entertaining. Below are answers to some of the most frequently asked questions about deck and porch construction in Pleasant Hill, including project timelines, material options, costs, design considerations, and what to expect throughout the construction process.
Before starting a deck or porch project, consider how you plan to use the space, the size and layout of your property, your preferred materials, and how the new structure will complement your home's design. Careful planning helps create an outdoor living area that is both functional and visually appealing.
Most standard deck or porch projects in Pleasant Hill take approximately 2 to 4 weeks to complete, depending on the size of the structure, design complexity, materials selected, and site conditions. Larger or more customized projects may require additional time to ensure quality craftsmanship and lasting performance.

We help you choose the right material based on durability, appearance, maintenance preferences, and budget.
A professionally built deck or porch can last anywhere from 15 to 30+ years, depending on materials and maintenance. Composite materials tend to last the longest with minimal upkeep, while natural wood requires regular sealing and care.
A deck is typically an open outdoor platform, often attached to the back or side of a home, designed for outdoor living and entertainment. A porch is usually a covered structure at the front or entry of a home, often integrated into the home’s architectural design. Both add value and functionality, but serve slightly different purposes in terms of design and lifestyle use.
