Boyle Heights

Room Additions contractor in Boyle Heights

Adding rooms to a house that has been standing a long time means the addition and the repair meet in the same wall. Where the new framing lands, the existing structure has to be opened, checked and made sound before anything ties into it, and that inspection belongs in the build rather than arriving as a surprise. Foundation and framing for the new footprint go in first, then the roof connection and the exterior skin, so the shell is closed before interior work starts. Finish then runs both ways: new rooms brought up to standard, and the rooms they open into patched, matched and repainted so the join does not announce itself.

Nothing is quoted for a Boyle Heights room addition until somebody has been to the house. The visit is free and the estimate that comes out of it is free as well. On a Hollenbeck or Breed Street property the walk covers two things at once: the addition itself, and the parts of the existing structure the new work will open into, since those are priced together or not properly at all. The written result is a detailed scope of work and a remodeling consultation about how the rooms will be used. Permit submissions belong to the company, not the client. MyCali Builders is licensed and insured under CSLB #1072368 and has been in business since 2020. Financing is available. Finished work carries a warranty of 5 years, and (310) 220-0903 takes calls and texts.

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.

Room additions in Boyle Heights are priced off the scope, and there is no published figure to quote. Two things move it more than size does: what condition the existing structure is in where the new work connects, and how much exterior repair travels with the interior finish. Both are visible at the property and neither is visible over the phone, which is what the free onsite visit exists to solve.

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

A Boyle Heights room additions estimate is a detailed scope of work, not a single number on a page. It sets out the new footprint, the foundation and framing under it, the roof and exterior connection, the interior tie-ins, and any repair to the existing house the addition runs into. A remodeling consultation goes with it. The onsite visit that produces it is free, and so is the estimate itself.
Staying in the house through a Boyle Heights room addition is the normal arrangement, because an addition is built outside the existing walls until the connection between the two is made. The shell goes up first, and the wall between old and new is opened later in the programme behind dust protection. Which rooms are affected, and in what order, is set out in the scope of work at estimate stage.
