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!

Aaron R. Concord, California

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!

Myla L. Concord, California

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

Chris W. Walnut Creek, California

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!

Frequently Asked Questions about our Bathroom Remodeling Services

A bathroom remodel involves many important decisions. The FAQs below help you understand the process and the level of service you can expect from Mares & Dow Construction & Skylights.
Mares & Dow Construction & Skylights delivers full-service bathroom remodeling, handling everything from minor updates to complete transformations. Our services include layout reconfiguration, custom showers, bathtub replacements, plumbing and electrical upgrades, heated flooring, tile installation, lighting design, vanity and cabinetry fabrication, accessibility improvements, skylight installation, and all finishing work. Every remodel is customized to match your style, space, and long-term goals.
Absolutely. If your bathroom feels crowded, outdated, or inefficient, we can create a brand-new layout that improves flow and functionality. Our team can relocate plumbing fixtures, expand or reconfigure the shower, add storage solutions, improve traffic patterns, increase natural light, or even merge or divide rooms when possible. We make sure the new layout aligns with your lifestyle, building codes, and the structural limits of your home.
Yes. We regularly remodel bathrooms in older and historic Bay Area homes, which often require special care. This includes addressing aging plumbing systems, repairing water damage, reinforcing framing, bringing electrical components up to code, improving ventilation, and replacing outdated or hazardous materials. We ensure the new bathroom blends modern comfort with the original character of the home.

The duration of a bathroom remodel depends on the scope of work, material choices, and structural considerations. Simple updates may take a few weeks, while full renovations typically range from 4–10 weeks. After inspecting your bathroom, Mares & Dow Construction & Skylights provides a detailed project schedule outlining each phase—demolition, plumbing, electrical, installation, inspections, and finishing—so you know exactly what to expect and when.

Yes. We offer full customization, allowing you to choose every design element of your new bathroom. This includes tile patterns, flooring materials, countertop surfaces, shower systems, lighting styles, custom vanities, mirrors, built-in storage, hardware, and color palettes. We help you compare materials, balance aesthetics with durability, and select finishes that match your vision and budget.

Preventing moisture damage is one of our top priorities. We evaluate your entire ventilation system, including exhaust fans, ducting, and natural airflow. Depending on what we find, we may upgrade fans to higher-capacity models, improve duct routing, install additional vents, apply waterproofing membranes behind tile, and enhance insulation in key areas. Our goal is to ensure your remodeled bathroom stays dry, healthy, and mold-free for years to come.

Yes. A bathroom remodel is consistently one of the highest ROI home improvements, especially in the Bay Area. Modern bathrooms attract buyers, improve daily comfort, reduce long-term maintenance issues, and often increase overall resale value. Even practical updates—such as new tile, lighting, or a more functional layout—can make a meaningful difference.

Getting started is simple. Schedule a free, no-obligation consultation, and our team will visit your home to review the existing bathroom, discuss your goals, explore design possibilities, and evaluate structural and plumbing conditions. We then provide a transparent estimate and a step-by-step plan outlining how we’ll bring your new bathroom to life—on time and within budget.
