What Do Insulation Professionals Do?

Insulation contractors provide both commercial and residential services, including installation, repair, and removal, and some Markham insulation professionals will also offer air sealing and HVAC system services. Common areas for home insulation services are the attic and basement, for both cosmetic and home energy needs.

Your Markham insulation contractor will recommend the type of insulation best suited to your house and budget, which may include one or more of the following:

  • Blanket insulation is rolled, is relatively inexpensive, and includes the popular fiberglass insulation variety.
  • Concrete block insulation is used for major renovations, like when building the foundation of a home.
  • Spray foam insulation is good for adding insulation to existing finished or irregularly shaped areas of the home.

As the services and expertise of each Markham insulation company will vary, reach out to a few different contractors to find who will be the right fit for your project needs. The list below is a selection of some of the services you can ask about:

Attic Insulation. Having a properly insulated attic is beneficial in many ways. The best attic insulation helps ensure your entire home maintains a consistent temperature – keeping your house comfortable and your utility bills down. A well insulated attic also prevents drafts, reducing any cold or hot zones in your house.

Insulation Removal. Home insulation can lose its efficacy over time, at which point a professional can remove the existing insulation and replace it with a better solution for your needs. For instance, fiberglass and cellulose insulation are often used in unfinished spaces, like attics. The insulation is eventually damaged by rodents or compression from boxes and furniture.
