Hidden Hills

Room Additions contractor in Hidden Hills

On a larger Hidden Hills property the addition is only half the problem; getting to it is the other half. The route for concrete, framing material and equipment is worked out before the programme is set, along with where material can be stacked and where the site line falls. Review timing sits beside that, so drawings and submittals are prepared early rather than in parallel with construction. The build then runs footings, framing, roof connection, weather shell, rough trades with inspections, and interior finish. Finish coordination is what makes the result invisible: floor material and direction, trim profile, ceiling height and paint sheen all matched to the rooms the addition opens into.

A Hidden Hills room addition gets a visit before it gets a number, and neither the visit nor the estimate is billed to the homeowner. On a property along Long Valley Road or Round Meadow Road the walk covers the footprint, the route material and equipment will take to reach it, and the finish standard the new rooms will have to hold beside the existing ones. A remodeling consultation runs with it, and the estimate arrives as a detailed scope of work. Permits are handled by the company rather than the client. It is licensed and insured, CSLB #1072368, in business since 2020, with financing available and a warranty of 5 years on completed work.

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 Hidden Hills - common questions

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

Yes. We have completed multiple Room Additions projects in Hidden Hills. Call (310) 220-0903 to schedule a free onsite visit, or compare public feedback on the customer reviews page.

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.

Yes. Permit submissions and the inspection scheduling that goes with them are handled as part of a Hidden Hills room addition, alongside the review timing the property brings with it. The drawings filed are the drawings built from. What a particular addition involves is established at the free onsite visit and set down in the scope of work rather than described in the abstract.
There is no published price for a room addition in Hidden Hills, and on a larger property the reason is worth stating plainly: access and staging can take as much solving as the square footage does. The route in, where material can sit, the structure under the new floor, and the finish standard the addition has to match are all scope items. The free onsite visit puts them in writing.

Yes. CA Contractor License #1072368. Fully insured for liability and workers compensation. The public record is on the CSLB lookup.

The first visit to a Hidden Hills property covers three things: the footprint, the access, and the finish. The addition is measured against the existing structure, the route for material and equipment is walked, and the finish standard in the adjoining rooms is looked at closely. The homeowner's plan for the rooms is the remodeling consultation. The visit is free, and the scope of work and estimate follow from it.
