Existing Homes
- Reinsulating an existing home is one way to significantly enhance the effectiveness of a home’s insulation
- Reinsulating is both convenient and affordable
- Provides the home with a better insulating seal through both adding insulation and sealing air leaks in the home’s envelope
It has long been known that many otherwise well insulated buildings were poorly sealed or had become poorly sealed as they were modified and as they aged. The lack of a proper seal was a leading cause of air leakage in and out of buildings.

Approximately 60% of all air leaks are in a home’s attic. Add to that the heat loss from an uninsulated basement (as much as 25%) and heat loss from exterior walls (around 15%). This air leakage results in moisture problems, wasted energy and wasted money.
Only recently has it become possible to address the problem of air leaks without significant and costly renovations. Today, Anchor Insulation professionals can identify the areas of greatest need and propose a cost-effective, energy-efficient resolution that will help increase the air-quality and savings. (Even small improvements to a building’s insulation can add up to big savings over time.)
