"Karol and his crew are very talented, efficient builders. We hired Karol to build a composite deck to compliment the pool we had installed in the back yard. It turned out beautifully. He is a great communicator and listener, prompt and reliable."

"Sigura made everything go so smoothly, even though it rained off and on. They made the timing work and got the entire project completed within just a few days. Their paint work was excellent, with clean lines, perfect color matching, and great detailing. They fixed my chimney top: My brick chimney was painted over with a cream color and looked so tacky, and now it actually looks like the bricks are in its original condition! There are no paint drips or sprays where there shouldn’t be. The garage looks brand new, but it’s really not. The entire crew and office team were polite, friendly and professional, making the whole experience amazing."

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

FAQs for garage building service projects in Sunnyvale, CA

A well‑constructed, properly permitted detached garage adds between $12,000 and $36,000 to a home’s resale value. Buyers appreciate the secure parking, extra storage, and flexible workspace, so appraisers often bump the property’s value accordingly. The exact return depends on the garage’s size, finishes, and how well it matches the main house, but most homeowners see a strong ROI when the build meets local codes and passes inspection.

Yes—once it meets local building codes and you secure the proper permits, a detached garage can be converted into living space. Finishing the interior, adding climate control, and ensuring safe egress effectively increase your usable square footage, though it may not always count toward the official listing. Skipping permits can trigger fines and even force you to undo the work, so always clear plans with your city first.

Most homeowners policies cover a detached garage under the “other structures” provision, but coverage limits vary. Review your declarations page and ask your agent how much protection you have for separate structures. If the limit is lower than the garage’s replacement cost, you can raise it for a modest premium. Confirming the details now prevents headaches if you ever need to file a claim.
