"Just can’t say enough good about these guys! They were professional, on time, easy to contact and did great work! Would give them 10 stars if I could. Not so easy to find good quality contractors anymore, these guys are the exception! Can’t say enough good, if you are thinking you are paying too much in utilities just contact them they can help! I got my air ducts and return sealed and insulation blown in...huge difference!"

Insulation FAQs, answered by experts

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.

Minimal, mainly occasional checks for damage or mold in extreme conditions.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process. 

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

Carriage, sliding, folding, and trackless pivot doors all replace a standard roll-up door. Glass doors and roll-up screens work well when you convert the garage into living space. Match the style to your driveway clearance and climate.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.
