"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."

"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

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

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.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
