"recently had the pleasure of working with Joel for an AC diagnosis and repair, and I couldn’t be more impressed with the level of service provided. From the moment he arrived, Joel displayed a high level of professionalism, courtesy, and technical expertise that immediately put me at ease. He quickly identified the issue, clearly explained the problem, and outlined the steps needed to get everything back up and running. What stood out the most was his thoroughness and honesty throughout the entire process. Joel didn’t just do a quick fix—he took the time to ensure everything was working properly and efficiently before he left. His professionalism, punctuality, and attention to detail were truly appreciated. It’s rare to find someone so committed to quality service and customer satisfaction. I highly recommend Joel for any HVAC needs—he’s a true professional who takes pride in his work. Thank you, Joel, for the outstanding service!"

Subcontractors questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
