"I have had multiple subcontractors while building our house. Bobby was the best! His work is fabulous. He communicated before, during and after the project - along with pictures! He meant what he said and said what he meant! A rarity these days! I would hire him again in a heartbeat!"

Insulation FAQs, answered by experts

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

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.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.
