Testimonials

On 10/6/2026 John Mortimer had this to say:
Nelligan Insulation replaced and topped off the insulation in our attic after water damage, and we were very pleased. Mike called ahead to schedule, came out to measure, and gave us straight answers about our existing insulation and what it would take to bring it up to current standards. His quote was fair and arrived the next morning. The crew finished the whole attic in under three hours. We would recommend Nelligan to anyone looking to improve their attic insulation.

Carter was wonderful to work with! He was always very easy to reach and answered any and all questions. He helped us brainstorm the best options for our budget. They will be our first stop for insulation needs.

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?

You can contact us through our website’s contact form, or call us directly. We’ll schedule a convenient time to assess your needs and provide a free estimate.
