"After the construction was complete, Randy was at our door for the final payment even though the final inspection was not done yet. Randy kept saying he would take care of it. 18 months goes by with Randy not doing anything to get the final inspection complete and stopped returning my messages. I had to call the town, electrical inspector, and electrician myself and try to get the final inspection completed. During all this Randy kept lying saying they are trying to reach out to you but you wonâ t answer your phone. Randy handled everything at the end horribly, I recommend not giving final payment to Randy until every part of the agreed upon contract is completed because he will take your money and run. I would never hire him again. Not to mention I am still fixing issues with our addition, our barn door fell off because they used terrible anchors. Bathroom tile Floor was put in with the wrong pattern, countless pieces of siding have fell off."

"We recently had a project from Bilt Rite completed. The owner Mike was very helpful throughout the entire process. Was quoted a 3 week timeframe to complete the project and it was done on time. Even added on a new kitchen floor installation after we signed a contract, still finished on time. It is a process for the entire project but Mike was very helpful throughout. Not pushy either. You will get exactly what you envision for your remodel. Good contractors are hard to find, this is your answer."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
