"Brayden and his crew were as friendly as a favorite relative! They worked professionally and neatly. And cleanup was complete and exact. The final walk down also proved to be encouraging as well, with everything put back in its place! I wouldn't hesitate hiring them again in the future ever! They were GREAT!!"

Insulation questions, answered by experts

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Yes, covering exposed wires is necessary for several important reasons. Exposed electrical wires pose significant risks, such as electrical shocks, fires, short circuits, and potential damage to your home’s electrical system. By properly insulating and protecting the wires, you can minimize the potential for accidents, prevent electrical fires, and ensure your electrical system stays intact.
