FAQ

What types of insulation do you offer?

We offer a wide range of insulation materials including fiberglass, cellulose, polyurethane spray foam, and blown-in insulation. Each type has unique benefits, and we’ll help you choose the best option for your project.

What is an energy audit and do I need one?

An energy audit is a comprehensive assessment of your building’s energy use. It identifies areas where energy is being lost and recommends improvements. It’s a great first step for anyone looking to improve efficiency and reduce utility bills.

How do I know if my home needs more insulation?

Signs include high energy bills, uneven temperatures between rooms, drafts, or ice dams in winter. A consultation or energy audit can confirm if additional insulation is needed.

How long does insulation installation take?

Most residential projects can be completed in a day or two. Larger or more complex jobs may take longer. We’ll provide a clear timeline during your consultation.

How can I get a quote or schedule a consultation?
