"Neil did the job fantastically and explained what he was doing throughout, always asked for an inspection to make sure it was done to my satisfaction. Pricing was extremely fair and he was timely and quick. Would highly recommend for any insulation work you need done. Can’t speak on the other work he does, but if it’s on par with what he did for me, then you’d be doing well."

"After contacting Jace, he came and did an assessment. He sat down and gave us a very fair bid on adding blown in insulation to our attic. We accepted the bid and he and his partner were back in a week’s time. They were very timely on arriving and were finished in their estimated time. They cleaned up the area very good. I highly recommend this company for any insulation needs."

"The consultation went fine. He was very thorough and looked at everything and talked us out of things that we did not need. I thought he was fair and honest. He did provide the consultation for free. He contacted us right away and got together with us in a day or two. The quote was quick and he followed up a month later. I have no complaints. We are not going to be doing anything this year but would consider him in the future."

Insulation questions, answered by experts

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.
