Landon and George did a great job with my place! They painted my garage and installed a new door, trimmed the evergreens, and put redwood mulch all around the house! My neighbors have commented about how nice it looks! Highly recommended!

Doorbell Installation questions, answered by experts

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
