What a bathroom remodel with Avis Builders and Design includes

A bathroom remodel with us is built around keeping water out of the structure. Before any tile goes up, we set the shower pan and apply waterproofing at the walls and floor. This hidden layer is what protects the framing and prevents the slow leaks that show up years later.

Plumbing and ventilation come next. We update supply lines and drains for new fixtures, and we make sure the room has a working exhaust fan vented to the outside. Good ventilation keeps moisture down, which protects your paint, drywall, and finishes over time.

The finish stage covers tile, the vanity, countertop, mirror, lighting, and fixtures. We set tile on a flat, waterproofed surface and slope shower floors correctly so water runs to the drain instead of pooling. Licensed subtrades handle the plumbing and electrical, with city inspections along the way.

How does the bathroom permit process work in Santa Clara County?

Bathroom remodels in San Jose typically need a permit once plumbing or electrical work is involved. We pull the permit under our license and schedule the inspections so the project stays compliant.

Addresses inside San Jose are handled by the San Jose Building Division, and homes in unincorporated county areas go through Santa Clara County. We check which office covers you before submitting.

California code sets requirements for bathroom electrical, including ground-fault protection at outlets near water. We wire and vent to those standards so the work clears final inspection.

Choosing bathroom finishes that handle moisture

Bathroom finishes have to stand up to water and humidity, so material choice matters more here than in most rooms. Porcelain and ceramic tile resist moisture well and clean up easily, which is why they are common on shower walls and floors. We help you pick tile sized and finished for the spot it goes.

Vanities and countertops face constant splashing, so we point you toward surfaces and cabinet materials built to handle constant water. A sealed stone or solid-surface top and a moisture-tolerant cabinet box will outlast finishes meant for dry rooms.

Ventilation and lighting finish the job. A properly sized exhaust fan pulls humidity out so it does not settle into paint and grout, and good lighting makes the space easier to use. We plan these practical pieces alongside the finishes so the room works as well as it looks.

Why hire a licensed general contractor for your bathroom remodel

Hiring a licensed general contractor gives your bathroom remodel one point of accountability from start to finish. We hold California contractor license CSLB 1142220, and we coordinate every trade, so you are not managing separate crews or chasing who is responsible for what. One team owns the schedule and the result.

A licensed contractor also handles the permit and inspection side correctly. Permits protect you, because inspected work meets code and shows up cleanly when you sell the home. Unpermitted work can cause problems with insurance and with buyers later, which is why we do it by the book.

Licensing carries real backing as well. A state license means the contractor has met California's requirements and carries the bonding the state asks for. You can look up license 1142220 on the Contractors State License Board website to confirm it is active before work begins.

Bathroom remodeling FAQs for San Jose and Santa Clara County

How do you prevent leaks in a new San Jose bathroom?

We waterproof the shower and wet areas before tiling and slope the shower floor to the drain. The waterproofing layer behind the tile is what keeps water out of the framing.

Can you convert a tub into a walk-in shower in a San Jose home?

Yes. A tub-to-shower conversion means new plumbing, a new pan, and fresh waterproofing. We handle the rough-in, permits, and tile so the finished shower drains and seals correctly.

Are you a licensed contractor in Santa Clara County?

Yes. Avis Builders and Design works under California contractor license CSLB 1142220, which you can verify with the state licensing board.

Which cities near San Jose do you serve?

We remodel bathrooms across Santa Clara County, including San Jose, Santa Clara, Sunnyvale, Cupertino, Mountain View, Los Gatos, Los Altos, and Campbell.

Do bathroom remodels need a permit in Santa Clara County?

Most do once plumbing or electrical is changed. We file the permit and schedule the inspections as part of the work.

Will I get a written scope and schedule before work starts on my San Jose project?

Yes. Before your bathroom remodel begins you receive a written scope of work and a project schedule, so you know what is being built and in what order. We review it with you and answer questions before the first day on site.
