"I was given several recommendations from Angi list, the most professional one of the 4 contacts I received was from David of EVERGREENPRO INSULATION. I needed to have a couple of interior walls insulated for soundproofing done. David was responsive, answered all my questions and gave me a reasonable quote. The other companies I talked to quotes were inline with Davids but the customer service just wasn't there like Davids. I even had one company tell me my project was too small for them to do..... Really? The next insulation project I need done I will just call David from EVERGREENPRO INSULATION and give them the job. A great job done by David and Jamie and would recommend and use them again."

"Sergio and his crew timely completed a complex insulation installation. Near Me Insulation LLC gets highest marks for flexibility in terms of traveling from Burlington to Glacier and completing the work with the highest skill level. The inside of my Ski Barn in Glacier has a height of 35 feet at the peak--several rooms with outside walls needed insulation. Sergio and crew also wrapped pipes and replaced window flashing with great care and expertise. Highly recommended contractor--reasonable price."

Insulation questions, answered by experts

Yes, you should insulate behind shower walls. Insulating helps prevent heat loss, which keeps the shower or tub from getting too cold and helps maintain a comfortable temperature in your bathroom. Additionally, proper insulation and air sealing can help prevent wall rot and moisture buildup. It is recommended to use a high R-value rated foam insulation combined with a vapor barrier.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.
