Your Home Should Work for You, Not Against You
Do you feel like your home in Walnut Creek no longer fits your lifestyle? Maybe your kitchen feels too cramped to cook in, your bathroom is stuck in the 80s, or your family is outgrowing the existing layout.
These frustrations are common and they only grow over time. But tackling a remodeling project can be overwhelming. From permits to choosing materials, managing timelines to coordinating multiple subcontractors, it’s a lot for any homeowner to take on alone.
That’s where Mares & Dow Construction & Skylights comes in.
A Trusted Remodeling Partner for Walnut Creek Homeowners
For over four decades, we’ve helped homeowners in Walnut Creek and across the East Bay solve these exact problems. As a licensed, bonded, and insured general contractor, we specialize in residential remodeling projects of all sizes. We offer full design-build services, which means you won’t have to juggle separate designers, architects, or permit offices—we take care of everything under one roof.
We listen to your goals, create a tailored design plan, and execute the project with precision, transparency, and integrity. From full home remodels to focused updates like a new bathroom or garage conversion, we deliver results that improve your quality of life and increase the value of your home.
What We Offer: Residential Remodeling in Walnut Creek
Each of our services is built on a foundation of craftsmanship, local expertise, and clear communication.
Siding Replacement
Curb appeal starts with the exterior. We specialize in James Hardie siding, known for its durability, fire resistance, and resistance to the salty air and winds common in the Walnut Creek area. Whether you need repair or full replacement, we’ll protect and refresh your home with professional-grade installation.
Skylight Installation
Natural light adds life to every room. We install VELUX skylights and sun tunnels to brighten dark hallways, bathrooms, kitchens, and more. Skylights not only improve aesthetics—they can reduce energy use, improve ventilation, and boost your mood.
Foundation Repair
Your home’s stability starts from the ground up. We offer expert foundation repair and seismic retrofits using Grip-Tite systems, protecting homes from structural issues and earthquake risks common in the East Bay. We’ll inspect, assess, and reinforce your foundation with industry-leading solutions.
Historical Restoration
Walnut Creek’s historic homes deserve to be preserved. We offer historical restoration services that retain the character of older homes while making them safer, more energy-efficient, and functional for modern living. We’re experienced with the materials, techniques, and care these special projects require.
Kitchen Remodeling
The kitchen is the heart of your home. Whether you’re after better flow, more storage, or a full modern makeover, we’ll design a space that fits how your family actually uses it. From custom cabinetry and countertops to layout improvements and lighting upgrades, your new kitchen will be beautiful and functional.
Bathroom Remodeling
Even small bathrooms can make a big difference. We remodel bathrooms to be more efficient, accessible, and relaxing. That might mean a walk-in shower, new tilework, double vanities, or upgraded fixtures that save water and energy—all while enhancing daily comfort and resale value.
Home Additions and ADUs
When your family grows or your needs shift, a home addition can provide the space you need without having to move. We build primary suites, second-story expansions, and fully permitted ADUs (Accessory Dwelling Units). Whether it’s for aging parents, a growing teenager, or rental income, we’ll help you design a new space that feels like it was always part of your home.
