"Brian, Bryan and Matt were our crew and were excellent. They were efficient, friendly and kind to me and my kids who liked to watch them work. The windows they completed look perfect. There was one window that they had to reschedule due to the space being very un-level. They ordered a brand new window and scheduled a new date to complete the job for the last window. They called as they were finishing up to explain everything. I also appreciated that I didn't have to be present for them to complete the job so that I was able to go to work."

"Brian is warm, professional, and we would definitely hire him again for handyman and home repair needs. His work is high quality, and he communicated with us clearly about the progress of the projects. Brian spotted a couple other small areas in our kitchen from an unrelated stalled project (unfinished corners between drywall sections; a sealed-off electrical outlet box), and offered to complete those for us, which was really helpful and generous. He's also great with dogs. :) As a heads up, Brian is in high demand and so there was a long wait-time between signing his quote and when he was able to schedule us in. But, his work is worth the wait. Strongly recommend."

Insulation questions, answered by experts

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

The easiest way to cover your HVAC ducts during construction is to use painter’s tape to affix plastic sheets over your vents and air returns in the area of your home where construction will take place. Keep in mind that closing off a portion of your system can put strain on your blower motor and air handler, so either shut the zone off or shut your system off while construction is underway. If you shut the zone, you can also hang plastic sheets over doorways to separate the construction area and keep dust contained.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.
