"I would highly recommend John P. Insulation. I got three quotes for my insulation job and they were the most professional during the estimate. They provided pictures of what they were going to do. They fully explained the job and what I should expect. The quote was fast and equal or lass than the others. On the installation day, they arrived when they said they would, covered my floors and completed the work exactly as they said they would. I had them foam seal, blow in insulation, install soffit vents and vent a bathroom fan. You will not be disappointed in the quality."

"Jacob and his team were great ! Everyone was super nice. I felt very comfortable in what I was told in regards to what needed to be done. After talking to many different insulation companies this was the only one that knew what I needed done and was able to do it at a great pirce. They managed to finish same day which was amazing. The results are so nice ! We didn't know what to expect as the end result since this is my first time dealing with insulation problems. But everything looks great !! I will definitely be going to them for any future projects. A million thanks to them ! I highly recommend these guys for your insulation needs. A trustworthy and hard working company."

"Rob was a great communicator and his promptness and knowledge were one of the main reasons we went with him over a slightly lower estimate we got. His sons did a good job of doing the work we required, which was messy work, and they left the place in pretty good shape with just some leftover bits of insulation here and there. If I have any additional insulation needs, Calnan would be my first call."

"Our central air conditioning system failed during the worst heat and humidity streak in more than a decade. When our AC contractor arrived to look at replacing the system, he pointed out that none of our 3 attics were insulated. We called Coleman Spray Foam. The put a highly knowledgeable rep on-site in less than 24 hours. One day later we received and signed their proposal. Crews arrived 2 days later and worked in unbearable heat and humidity in our attics until we had R50 insulation (needed for AC/Heat Pump). I would have them back in a heartbeat and highly recommend them for anyone in need of spray foam insulation."

"I highly recommend Green Way. The folks from Green Way were professional and they delivered high quality work at a great price. The work involved applying foam to exposed roof deck in the attic, and applying blow-in insulation between unexposed roof deck the interior walls. I'm very pleased with the outcome."

Insulation questions, answered by experts

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

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.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.
