Room additions give San Diego homeowners a way to grow their home without leaving it. Whether you need a new bedroom, a home office, or a larger living area, F-CON manages the full scope of work as your general contractor. We handle design coordination, structural planning, and city-required plan submittals under the California Residential Code and San Diego Municipal Code.

Our team coordinates each trade, keeps the work area organized, and communicates clearly at every stage. The result is a finished room that matches your existing home in structure, finish, and flow.

We have used F-Con on a couple of family projects. Cameron was very fast responding to us. Also, the work done was excellent. I would recommend this company anytime. The employees were courteous and did an outstanding job on our property. And, I plan to have them do another job for me soon.

Every interaction was professional, pleasant and timely, from requesting estimate to the completion of the roof. The men were on the job everyday at the same time and always cleaned up. They corrected issues found and kept us informed. We had a problem with the way awnings were installed and causing leaks in the home, they were able to lay material to eliminate the issues. I don't have to use air conditioning as much anymore. Before the new roof, it was so hot inside. With the new roof, we really haven't had to run the air at all for the most part. What a great experience all around. Hard to find such quality workmanship and a company that cares about doing a professional and complete job. We could not be more pleased with the results.

The service provided by Cameron and his company were second to none and the quality of work was above and beyond expectations. The work was done on schedule both times his company was used for our home and our shed. I would recommend and have recommended him to anybody needing roofing repairs.

I want to thank you for the outstanding work you and your team did repairing and installing our new roof. It is refreshing to have such a quality job done on schedule and within our budget. Even with all the unique challenges of our roof structure, you managed to come up with creative solutions. I have appreciated your responsiveness to come back and do additional jobs for us and want to give you a strong positive reference. I would be glad to serve as a reference for any future customers. Thank you again for excellent work.

Working with Cameron has been an amazingly easy and effortless experience. From the beginning, he's been quick to respond to any and all questions, and he goes the extra mile to make sure every step of the process is smooth. He sets appropriate expectations when it comes to the timeline and work schedule, plus he does phenomenal work at a great price. I can't recommend him enough, and if you're in the market for a new roof, you can be confident you're getting taken care of by Cameron.
