The existing insulation in Falls Church, VA was piled deep, but there was air leakage, non-consistent coverage, low spots, and it was just nasty!!!

We removed all of the old insulation, air sealed any leakage points, and blew in new TruSoft blown-in cellulose insulation for a nice,  thick, even coverage.

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

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.

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!

Job Stories From Falls Church, VA
Attic Mold: Causes and How to Fix It

Attics are some of the hottest and most humid parts of a house, especially if they are poorly or improperly insulated. These conditions are ideal for mold growth because not only does the area have high temperatures and excessive moisture, it is also usually dark. Attics are usually supported by wooden joists and beams as well which is an excellent organic food source for mold. While most homeowners aren't usually in their attic frequently, there are some easy tell-tale signs that there is a present mold issue.

Conditions in the Attic

If there is a mildew odor either in the attic or the surrounding rooms, then there is a moisture problem that is causing mold to grow. Musty odors are not something to ignore!

If there is wet or damp insulation in the attic, this is a very bad sign as well. Wet insulation loses its ability to properly condition spaces and easily becomes moldy. This causes not only higher HVAC bills due to inefficient insulation, but also poses a threat to air quality due to the spread of mold.

Any staining or rot on the wooden areas of the attic is a sign that mold is present too. If the mold growth is black, this is possibly indicative of toxic black mold growth. This is an immediate issue that needs to be resolved.

If the attic is extremely stuffy, this is a sign that it is not properly ventilated or insulated. The effects of improper ventilation and poor insulation usually lead to trapped moisture that causes mold growth.

What Do I Do About Mold in the Attic?

As with most home improvement projects, there is a DIY option. This is not recommended, however. Attics are dangerous areas of the house, regardless of when it was built. Falling through the rim joists, stepping on a nail, or inhaling air contaminated with mold or animal droppings are all possibilities. Even the most experienced technicians still come across surprises on the job. 

Fixing the mold issue is only half the battle: what really needs to be done is a full evaluation and diagnosis of the attic to identify where the moisture that is causing the mold is coming from. At that point, it is in the homeowner's best interest to address the root cause of the issue, not just the mold growths.

Comfenergy specializes in fixing home performances at their root cause. Call us today if your home is having any of these symptoms!

Basement renovation to prevent moisture and mold.
Project Location: Falls Church, VA
We purchased this home earlier this year and realized during the summer that the attic was not well insulated. We also had a chimney issue that we repaired that we thought may help, but it hasn't too much. As we get this trial run of colder weather, we're realizing that the poor insulation is making it chilly upstairs. We have three small crawl spaces (one in the office, two in the master). The office crawl space appears to have some older insulation, but it does not appear that the bedroom has any.
