Construction Company reviews in Gualala, California

We hired Oscar for a comprehensive waterproofing overhaul of our 1983 Don Jacobs Sea Ranch home, and his performance has been outstanding.

When we acquired our home in the summer of 2024, it was plagued with numerous issues, including water trapped in the flat roof, deteriorated Redwood siding, and leaking windows. Oscar and his team adeptly tackled these challenges by installing new Boral Board and Batten Siding atop fresh plywood and waterproofing layers, replacing the compromised windows/sliders with new Marvin fiberglass models, and adding a new roof. Our home stayed dry and leak-free since.

Following the exterior work, we shifted focus to the interior.

Oscar's collaboration with the original architect, Don Jacobs, has infused the project with an additional layer of authenticity and precision. They are currently rejuvenating the interior, the front screening/storage area, and the previously rotten rear deck, adhering faithfully to the original designs and specs. The renovation includes freshened up touches such as new clear cedar interiors, smoothed drywall, Mid-Century Plycraft built-ins, window seats, and Vertical Grain Douglas Fir details/reveals, all enhancing the distinctive Sea Ranch style while feeling original.

Oscar's team exemplifies meticulous attention to detail, adding thoughtful finishes like copper flashing above windows with slight reveals and a copper roof over the electrical panel, which significantly enhances the craftsmanship. The experience of working with him has been seamless and exceptionally rewarding.

Stage 2 Complete - Interior just finished today, uploaded a video showing the interior finish work and details. Oscar and his crew really made this well-worn, water-stained interior feel brand new, clean, and very Sea Ranchy.

Stage 3 Completed a few months ago - Colin Construction built us a brand-new deck with a continuous concrete foundation, per Don Jacob's plan to keep the skunks out. The deck and rails are a mix of Redwood, Trex, Copper, Aggregate Concrete, and Bronze hardware - Oscar's team made sure everything was beautiful and built to withstand TSR elements.

They built us all new fencing with Boral and a new trash enclosure with a concrete pad that is both raccoon and gopher-proof.

In the courtyard, they installed my flagstone with living grout(all local natives).

They also moved our driveway. Installed a new Apron. New Sea Ranch brown gravel and redwood sheep fence.

Oscar Colin and his crew closed in an outdoor room for us. The space was taken down to the studs and built back up into a beautiful finished room. Stairs, fireplace, fir wood vaulted ceiling, huge windows…. There was excellent communication all along the way,. The team displayed the highest degree of professionalism and respect, showing up every day at the agreed upon time, cleaning up at the end of the day. Absolutely no complaints. Great company to work with.

We recently hired Colin Construction to install new cedar siding on the South and West sides of our home and install nine new windows.

After speaking with several contractors, the choice was clear to us. We chose Colin Construction because we found Oscar to be extremely knowledgeable and a great communicator along with being a problem solver and, as we discovered, a perfectionist. For example, our garage door needed siding, a project that required exceptional skill to get it right. Oscar took on the project himself. Talk about attention to detail. Many cuts, many exact measurements. The garage door’s appearance improved immensely; it looks stunning.

The crew at Colin Construction (particularly Romero and Arturo) showed up on time every morning and did superior work every day until the project was completed.

These projects can be stressful for the homeowner. We always felt like we were Colin Construction’s top priority. That was very reassuring.

Honesty, integrity, professionalism and quality are what Oscar and his crew bring to the job every day. If you seek a skilled contractor and crew you can rely on, contact Oscar at Colin Construction. You’ll be glad you did.

Oscar is a gem! He and his crew do top notch work and he is a delight to work with! Oscar has done exterior and interior jobs for us including re-siding parts of our house, window and door replacement and a full kitchen remodel. We could not be more pleased with the kitchen! In particular, his tile work is impeccable and his cabinet makers are equally skilled.

Oscar is meticulous and thorough in everything he does and is responsive and addresses any concerns quickly and seamlessly. Oscar and his team are tidy and respectful of your home and easy to have around. In addition, his fees are reasonable given the quality of work he provides. We are embarking on additional remodeling projects and only want Oscar and his crew to do the work!
