La Crescenta

Room Additions contractor in La Crescenta

Putting rooms on the back of a La Crescenta house adds a roof plane, an exterior wall and a new area of ground that water has to get off. Those three are drawn together rather than in sequence, since the roof line decides where run-off lands and the finished ground level decides where it goes next. Structurally the job is standard: footings, floor framing at the existing floor level, walls, the roof tie-in, then a weather-tight shell before rough trades and inspections. Interior work closes it: insulation, drywall, flooring carried through from the existing rooms, and trim matched closely enough that the join between old and new stops reading as a seam.

A La Crescenta room addition is measured before it is quoted. At a house in Crescenta Highlands or over by the Montrose adjacent blocks the visit takes in the new footprint, the roof plane the addition will add, the exterior it has to blend into, and where water leaves the ground once the new area is built. The visit is free, and the free estimate written afterwards is a detailed scope of work with a remodeling consultation attached. Permits are handled. The company doing the work is licensed and insured, carries CSLB #1072368, and has been in business since 2020. Financing is available, and there is a warranty of 5 years on completed work.

La Crescenta area

An addition changes the shape of the house, so the lot leads. What is left of the yard once the new footprint lands, how the new roofline meets the old one, and which existing rooms lose a window all come first. A Foothill Boulevard corridor property gets that walked in person before there is a drawing.

Neighborhoods served: Crescenta Highlands, Montrose adjacent blocks, Foothill Boulevard corridor.

Near: Foothill Boulevard, Crescenta Valley Park, Angeles Crest Highway.

What is included

  • Added living space planned around the existing home

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.
