"Abraham and his team, Will and Josh, did a great job of removing old insulation, sealing air leaks and adding new insulation to the attic in my 46 year old home. The old insulation was blocking air flow through the attic and this needed to be addressed, which they did. They were very professional and hard-working. Communication was excellent and everything was well explained and the process photographed. We are glad we hired Abraham for this project!"
"They were prompt, friendly and knowledgeable about their product. In an out in about two hours from set up to completion. Iâ ve already noticed a difference in my house. Definitely would recommend them for foam insulation."

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."
"The installers were careful, courteous, & thorough. They left the premises clean & uncluttered. I can't wait to see the difference in our heating bill. They installed spray foam in the rim joist, a small ceiling in the basement & the walls in a crawl space."
"Abraham and his team were a fantastic help. Their service was life changing for our family. We live in a 120 year old home that had almost no insulation in the walls. Our HVAC could never keep up on cold, windy days. The last 3 winters there were times we had to go stay elsewhere as the home was too cold. Fast forward to this winter, after they completed the work we saw an immediate return. Bills went down and the home is comfortable. Heck there were times our HVAC stopped since it was so warm! They were very professional and worked around our hectic schedule. I would fully recommend them to anyone in need of insulation services."
Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.
The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.
If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.
The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.
Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
