"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"Installation of insulation went well; EZinsul was very thorough. However, there were some clumps of insulation and a thick film of fiberglass covered everything, despite their sweeping up to â industry standardsâ . Jacob & I talked; he came back and dusted to my satisfaction. I appreciated this attention he paid to my project. I would highly recommend EZinsul. Ruth Ann White"

"They came on time and the insulation looks well done. Didn't do a great job of cleanup - some old insulation around on the ground. They weren't prepared for the steep driveway and didn't have long enough tubing, so they had to improvise by using the neighbors driveway. Would be good for them to enhance their capabilities there."

Insulation questions, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.
