Here are some important questions to ask an insulation company in Thunder Bay, along with the responses that suggest they’re the ideal choice for your insulation project.
What types of insulation materials do you offer, and which is best for my home?
Insulation companies in Thunder Bay offer a variety of materials, such as fibreglass, spray foam, cellulose, and foam board. They should also be able to explain which material is most suitable for your home type and energy efficiency goals.
Do you conduct a home energy audit before recommending insulation?
Many insulation companies in Thunder Bay will offer or recommend a home energy audit to assess where your home is losing energy. This audit helps determine the most effective insulation solution, so you don't overspend on unnecessary materials or services.
Do you clean up after the job is done?
Ask if your chosen insulation companies in Thunder Bay will clean up any debris, insulation material, and equipment after the job is finished, leaving your home neat and tidy.
Do you offer any energy-efficient or eco-friendly insulation options?
Insulation companies in Thunder Bay will usually offer environmentally friendly materials like cellulose or spray foam with low global warming potential (GWP). They should also be able to explain how these options improve energy efficiency.
How long will the insulation installation take?
The right Thunder Bay insulation company will give you a clear timeline for installation based on the size and scope of the project. They should also let you know what to expect before, during, and after the installation process.
Spray foam insulation is an excellent choice for homes in Thunder Bay, particularly for those seeking maximum energy efficiency. It provides superior air sealing, reduces heating costs, prevents moisture issues, and improves overall comfort by eliminating drafts.
Some signs that your home may need more insulation include uneven temperatures between rooms, cold drafts, high energy bills, or visible gaps in attic or wall insulation. We recommend scheduling a consultation with an insulation company in Thunder Bay where they can assess your home and recommend the appropriate solutions based on its specific needs.
Many Thunder Bay insulation companies provide warranties on both the materials we use and the installation process. The specific terms vary depending on the insulation type, but their warranties are designed to give you peace of mind and protect your investment. They may also offer follow-up services if any issues arise.
Check if your chosen insulation company in Thunder Bay is fully insured. This means the team will be trained to follow all local building codes and safety standards. They should also carry liability insurance to protect both you and their workers in case of accidents or damage during installation.
