Before After
Attic Air Sealing in Lorton, VA Attic Air Sealing in Lorton, VA

This Lorton, VA homeowner was looking for ways to lower their utility bills.  Comfenergy found a ton of air leakage in the attic allowing the heated and cooled air to leave the home.  This before and after pic set is showing how we air sealed around an air duct that went into the top floor. By closing this gap, we prevent any air travelling between this space.

This set of before and after photos shows the difference between light, fluffy fiberglass insulation and new TruSoft cellulose insulation in an attic.  Here are the differences you may not know:

1. Fiberglass is more susceptible to something called "wind washing".  In a vented attic assembly wind can blow around in the attic and it can easily pass through the fiberglass.   TruSoft cellulose packs tighter and it's harder for wind to travel through it.

2. Rodents and insects LOVE fiberglass.  They nest in it and make it home.....right above your head.  TruSoft cellulose is chemically washed with a liquid borate which deters rodents and insects by irritating their respiratory system.

3. TruSoft cellulose has a higher R value per inch than fiberglass.

4. TruSoft cellulose is also less succeptible to flame spread than fiberglass as well.....

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call or click today!

I'm looking to get the garage insulated. Our master bath is right above the garage and it gets very cold in the winter. Last year the pipe to the tub froze. I'm pretty sure there is either no or very little insulation in the garage ceiling or walls. Thanks, Dana
Vicinity of Hagel Circle in Lorton
I want to replace or supplement my attic insulation in at least one property, possibly two.
Vicinity of Dogue Indian Circle in Lorton
I am an extremely light sleeper and regularly lose sleep to outside noises (dogs, cars, people in their backyards, trains, etc). I was reading about window inserts for sound reduction and was wondering about your interior window inserts as a possible option for my three bedroom windows. I'm really doing research right now to decide whether alterations to my windows will suffice or if I need to go the "goop behind new drywall" route...and which option may or may not reduce the most noise disrupting my sleep.

Hi, I'm not sure if I contact the right company, but we experience a lot of thermal expansion of ductwork in our house, and I'm wondering if that is something you can remedy. I also need to insulate the attic above my garage and make it fire block. Thank you, Johnny
