We start with how you use the room. A kitchen that keeps its sink, range and refrigerator in place is a lighter project than one that gains an island or opens to the living room, which adds framing, new circuits and a permit. We walk through a few layout options with you before anything is ordered, so you can compare scope and price. Bathroom remodels range from new tile, vanity and fixtures to full rebuilds with a walk-in shower and better ventilation. We plan waterproofing and drain slope with the design, then coordinate the trades and the inspections so one team carries the project from demolition to final walkthrough. See [kitchen remodeling](https://ecosremodeling.com/services/kitchen-remodeling/) and [bathroom remodeling](https://ecosremodeling.com/services/bathroom-remodeling-services/). ## Can I add an ADU or an addition to my San Mateo home? Usually, yes. California law lets most single-family lots add an accessory dwelling unit, and often a junior ADU inside the house as well; California HCD publishes the state ADU and junior ADU law cities apply. The usual paths are a detached backyard unit, a garage conversion or an addition that extends the main house, and lot size, setbacks and utility routes decide which fits. Each San Mateo County city runs its own permit review. Plans for a San Mateo address are filed with the City of San Mateo, whose City Hall is at 330 West 20th Avenue, while a project in Burlingame or Foster City is filed with that city. We prepare the drawings, submit them, answer plan-check comments and build through final inspection. More on our [Bay Area ADU builder](https://ecosremodeling.com/bay-area/adu-builders/) and [home additions](https://ecosremodeling.com/services/home-additions/) pages. Roofing and exterior project by EcoStar Remodeling & Construction Exterior project by EcoStar Remodeling & Construction ## What roofing, foundation and seismic work do San Mateo homes need? With the San Andreas Fault close by, seismic work belongs in the plan for any structural job. On a house with a raised wood floor and a crawl space, a brace and bolt retrofit sheathes the cripple walls with plywood and bolts the frame to the foundation, and California’s Earthquake Brace + Bolt program offers retrofit grants for qualifying houses in eligible ZIP codes. When we replace a roof we check the decking and flashing underneath, and we look at drainage so water moves away from the foundation. Outside, we pour driveways, lay pavers and build decks. See [roofing](https://ecosremodeling.com/services/roofing-services/), [foundation repair](https://ecosremodeling.com/services/foundation/) and [driveways](https://ecosremodeling.com/services/driveways-contractors/). ## Who runs your San Mateo remodel?

I reached out for bids for a new roof. I met Zane over the phone and set up a meeting. He arrived and we talked about what I was interested in doing. I told him the roof was the priority because my insurance company threatened to cancel me. He agreed that my roof did need a replacement and the reason why insurance companies have issues with old roofs. He laid out some numbers for me about what I was interested in. We talked roof extension, gutters, solar panel cost, battery system an a going with a lighter color. All these things and also some interior lighting the kitchen area. I have to say that after a few hours of his time we reached and agreement on what I was hoping for during the t he process. How fast, the time involved and price were considered. The contract was the biggest issue of course and how much I could afford. EchoStar made me a good offer for the work and I felt very satisfied with the decision to go with eccstar. I was happy with how fast the roof was stripped and preped. The work crews were amazing and did very good work. I did not have many concerns and if I did there was always someone to help answer my questions. Zane the project manager was in contact with me the whole time. I was very happy with his customer service and also his caring of my satisfaction throughout the construction phase. I would highly recommend this company for any construction needs. They have a lot of good worker and I was very impressed and happy with my decision going with EcoStar.

First of all, thank you, Kennet. I truly appreciate the incredible work you and Ecostar Remodeling & Construction did on my attic insulation. I’ve done several home improvement projects over the years, but I’ve honestly never experienced this level of professionalism, precision, and care. From the initial inspection to the final walkthrough, everything was explained clearly and handled flawlessly. The crew was punctual, clean, and extremely detail-oriented. The work was done beyond code, using high-quality materials, with zero shortcuts. The difference in temperature and overall comfort in my home was immediate, and I noticed improved energy efficiency right away. I couldn’t be happier with the results. If you’re looking for a contractor you can truly trust in Oakland, Ecostar is on another level. Highly recommended.

I wasn’t sure how involved this project would be, but the crew really simplified things. They handled each step steadily, kept me updated, and managed the tricky parts without making a big deal of them. The upgraded space feels more modern and easier to use, and the whole process felt surprisingly smooth. Posted on Google Google Kai profile picture Kai Google star 1Google star 2Google star 3Google star 4Google star 5Trustindex verifies that the original source of the review is Google. I reached out to Rotem and his company to see if my home’s roof was still under warranty. Unfortunately, the warranty did not transfer over but he gave me a good quote on the repair. Rotem is very professional and his explanation of the work was thorough. He also advised on which repairs around the house can wait, and what needed to be prioritized. He’s a good guy and a pleasure to deal with. If you’re shopping around for quotes, Rotem and Ecostar is a great point of reference no matter which company you go with. They are on my short list of home repair contractors.
