Do you want to improve your home energy efficiency?

Checking your home's insulating system is one of the fastest and most cost- efficient ways to use a whole-house approach to reduce energy waste and maximize your energy dollars. A good insulating system includes a combination of products and construction techniques that provide a home with thermal performance, protect it against air infiltration, and control moisture. You can increase the comfort of your home while reducing your heating and cooling needs by up to 30% by investing just a few hundred dollars in proper insulation and weatherization products.

We can provide you insulation that will help protect your home against all kinds of heat transfer and also reduce disturbing sounds from your neighbourhood.

Should I insulate my home?

The answer is probably "yes" if you:

  • have an older home and haven't added insulation: in a recent survey, only 20% of homes built before 1980 were well insulated.
  • are uncomfortably cold in the winter or hot in the summer – adding insulation creates a more uniform temperature and increases comfort.
  • build a new house or addition, or install new siding or roofing.
  • pay excessive energy bills.
  • are bothered by noise from the neighbours – insulation helps to muffle sound.
  • are concerned about the effect of energy use on the environment.

These are all common problems that many people have in their home or office. If you are looking for professionals to help you solve any of these problems, you are on the right place here!
