Westlake Village

Room Additions contractor in Westlake Village

An addition that faces a yard is really a pair of projects meeting at a wall. Where the new room opens to the outside, the size of that opening decides the header above it and with it the beam behind that, so it gets settled with the structure rather than at the finish stage. A wide slider, a set of French doors and a fixed window with a single door are three different structural decisions. Floor level is the other one: matching the interior floor to a patio or deck outside removes a step and changes how the two spaces get used. Drainage and the threshold detail then have to keep water out of a room that now sits close to grade.

The record behind the work is short and checkable. Trading since 2020. Over 580 completed projects since 2020. Yelp top contractor reviews 2023-2025. Licensed and insured, CSLB #1072368. Attached to that record is a plain process: a free visit to the house, then a free written estimate in the form of a detailed scope of work, with a remodeling consultation covering structure, materials and finishes. Permit filings and inspection bookings are handled. Financing exists. A warranty of 5 years covers the completed addition. Call or text (310) 220-0903 to book.

I recently hired My Cali Builders for a backyard remodel and couldn't be happier. Danny and his team were professional, punctual, and easy to communicate with. They really paid attention to the details and brought my vision to life. The quality of the work exceeded my expectations from start to finish. Everything was done cleanly and on schedule, which I really appreciated. Danny made the whole process smooth and stress-free. The backyard now looks amazing and feels like a completely new space. I would definitely recommend them to anyone looking for reliable contractors.

I began my Yelp search for a company to perform structural repairs and ultimately chose 5 companies, scheduling each of them for a representative to visit and discuss my needs. I chose My Cali Builders based upon Danny's (owner) review of the work and how he defined the scope of the work. The other representatives vacillated on the scope of the work and attached various caveats. My Cali Builders also gave me the best bid. So I hired them and boy, am I glad I did. Work was performed quickly, efficiently and the finish work was excellent. Every task I initially discussed with Danny was completed. Danny's crew including Francisco and Jaime, were top notch and pleasant. Each day, refuse and trash were removed. Every day, Danny either visited or texted to advise on progress and to insure the work was progressing as discussed and to ask if I was satisfied and happy. I can't convey in words how much I appreciated My Cali Builders. Look no further, they are the best I've ever encountered.

Danny Raz is a man of action; the work was done promptly and even finished ahead of schedule. The workers were polite, respectful, of cleaned up well after the job.

FAQs

Room Additions in Westlake Village - common questions

Answers to the most common questions about this service in your area.

Financing is available. Nothing further about it is published, so treat the page as confirming that it exists and the conversation as where it gets explained. In practice the sequence is the free onsite visit, the detailed scope of work it produces, and then how the project gets funded. Ask at the remodeling consultation or on the phone at (310) 220-0903.

Room additions typically run 2 to 4 months from permit approval through punch list. We manage the submittal and inspection schedule. We give you a written schedule during the estimate so milestone dates are clear before field work starts.

Room additions require permits and we manage the submittal and inspection steps with you. We flag any city-specific requirements during the estimate visit. You can also step back to the main Westlake Village page to compare related local services.

This site quotes no price for an addition. The number is assembled from the scope, and on a larger layout the pieces that move it are the footprint, the structural work at any wide opening, how services reach the new rooms, and the finish level. The free onsite visit and the written detailed scope of work are where a figure actually comes from.

Yes. CA Contractor License #1072368. Licensed and insured. The public record is on the CSLB lookup.

Someone comes to the house and the meeting is a working one. The rooms the addition would open off get measured, the ground it would sit on gets looked at, and the conversation covers what the space is for and how it should connect to the rest of the layout. You leave with a detailed scope of work and a remodeling consultation, both free, and no obligation to go further.
