Proper Insulation Will Help Decrease Your Energy Bills All Year

As a Connecticut homeowner, you know full-well how harsh the winters and summers can be here. One of the best ways to save on your energy bills for years to come is to update your home's insulation. Dr. Energy Saver Of Connecticut is a professional blown insulation contractor, catering to residential homes in Darien and nearby. Hop on the path to savings by contacting us today! 

Dr. Energy Saver Of Connecticut likes using blown-in cellulose insulation for many homes due to the fact that it is one of the best types of insulation that can match or exceed the insulation value of fiberglass, with R-values as high as R-4 per inch. That is because, unlike fiberglass which doesn't stop air movement, cellulose does a good job of slowing or stopping air leaks that can waste energy and cause cold drafts. It is also eco-friendly, as it takes much less energy to manufacture than other types of insulation, and is even made from recycled newspaper. Plus, blown-in cellulose is resistant to fires, mice, and mold, so you can count on the insulation value lasting.

Insulation Services We Offer:

  • Home Energy Evaluations
  • Sealing Air Leaks
  • Radiant Barrier Installation
  • Ice Dam Prevention
  • Floor Insulation
  • Attic Insulation
  • SilverGlo Insulation

Ice Dam Repair & Prevention Solutions

Homes in this area of the country are exposed to frigid temperatures and snow every winter.  Because of this, ice dams are common issues that homeowners deal with.  Ice dams are caused when the heat inside your attic warms the underside of the roof and causes ice and snow to melt. Ice dams can cause serious damage to your roof and can leak into your attic. When we talk about ice dams, one of the most frequent questions we get asked is " how do I prevent or repair ice dams?".  Preventing ice dams is fairly simple with the use of proper insulation and air sealing. If your home is facing ice dam issues, contact the experts at Dr. Energy Saver Of Connecticut for a FREE quote today!

Moved into our house in July of 2020 and had new gutters installed. Since we have been getting all this snow, we appear to be getting ice dams and icicles forming on our gutter line. Want to determine if it is an insulation issue causing the ice dams.
