Framing is where an addition either becomes part of the house or sits next to it. Wall plates are set to the height of the existing top plate so ceilings line through. Rafters or trusses are cut to the pitch already on the roof, and the new plane meets the old at a ridge, a valley or a saddle that has to be detailed rather than improvised. A ledger bolted into old framing is only as good as the framing it lands on, so what is behind that wall gets opened and looked at before the connection is designed. Sheathing, weather barrier and flashing then close the shell, and finish coordination begins on a structure that is already dry.
The estimate here is a document, not a number on a card. It is produced after a free onsite visit, it is free itself, and it comes as a detailed scope of work with a remodeling consultation, so the framing package, the roof work and the finishes are all named. Permit submissions are handled by the company. Financing is available. What gets built carries a warranty of 5 years. CSLB #1072368 is the licence, the company is licensed and insured, and it has been in business since 2020. Reach it on (310) 220-0903.

Footings, the framing tie-in, the roof line and the spot where an existing wall opens into new space are resolved before an addition goes up, because it is fresh structure joined onto a house that is already finished.

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.
Was very impressed! Prompt. Highly professional. Thorough. Excellent feedback and service while response completing my job. I absolutely would hire them again and recommend them without any concerns!
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.

Answers to the most common questions about this service in your area.
Yes. We have completed multiple Room Additions projects in Simi Valley. Call (310) 220-0903 to schedule a free onsite visit, or compare public feedback on the customer reviews page.
No duration is published, and the honest reason is that an addition is not one job but a chain of them. Progress gets reported against the milestones in the scope of work: foundation, shell, rough trades, close-in, finishes. Asking where a project stands is then a question with an answer rather than a guess. The specific sequence is talked through at the remodeling consultation.
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 Simi Valley page to compare related local services.
This site carries no prices. On an addition the number follows the scope, and the framing and roof work is where it moves fastest: extending a simple roof plane is a different job from reframing one. Foundation, service runs and finish level fill in the rest. The free onsite visit and the written scope of work are how a real figure gets reached.
Yes. CA Contractor License #1072368. Fully insured for liability and workers compensation. The public record is on the CSLB lookup.
Text or call (310) 220-0903 and describe what you want the addition to do. A visit is arranged at the property, the existing structure is measured and looked over, and options for where the new space can go are discussed on the spot. The result is a detailed scope of work and a remodeling consultation, free, with no commitment attached to either.
