"Marvon's crew did an excellent job with renovations to the main floor of our 36 year old home. The work ethic his crew demonstrated was exception now days. They take pride in their work and truly want the customer to be happy with the end product. I would hire them again if I need this level of work done again."

" "I recently hired Robinson General Construction for a complete bathroom remodel, and I couldn't be happier with the results! From the initial consultation to the final walk-through, Cole and Gavin were very professional, courteous, and highly skilled. They listened to my ideas, offered helpful suggestions, and stayed within my budget. The quality of their workmanship is outstanding, and they paid attention to every detail. My new bathroom is beautiful and functional, and it's exactly what I wanted. I highly recommend Robinson General Construction to anyone looking to remodel their bathroom." "

"Perfect. I enjoyed getting to sit in the storm shelters at their showroom to help with size selection. After signing up for the install, they connect you to an online portal to manage the contract and to update building permit number, etc. Installation was prompt and clean."

FAQs for garage building service projects in Decatur, IL

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.
