Before and After Pictures from Fredericksburg
A "Naked" Attic Gets Insulated

A "Naked" Attic Gets Insulated

Before After

This attic had very little insulation and there was significant air leakage occurring, which was causing comfort issues in the home and high humidity. The blown-in cellulose will now keep this attic properly conditioned and further insulate the vents/ductwork.

Whole house fans are GREAT!!  (For about 2-3 weeks of the year) For our geographic area.  It's way to humid and hot during most of the summer, and way too cold obvisouly in the winter.  During this 45-48 week time period, they do nothing more than allow energy loss in a home.

The before/after pics that follow show you what Comfenergy can do to allow you to keep your whole house fan for when it makes sense....but not loose energy the rest of the year!

This homeowner had moisture damage from sweating ductwork. In the 'Before' picture, you can even see the moisture pooling on the duct! The ducts were not insulated and the attic was poorly insulated. We applied our Tight 'N True encapsulation system to the sweating ducts to ensure that they stay dry and the house stays comfortable.

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.

Humidity in Rooms Above Garages: A Common Issue

While uncomfortably humid rooms are a common complaint among customers in the summer months, there is one area of the home that seems to have the most issues: spaces above the garage. Generally, garages aren't insulated very well. They tend to be hot. humid spaces that are prone to condensation. When an uninsulated garage is directly below a usable room, the hot, humid air rises and compromises the conditions of the room. This is why it is important for homeowners to make sure the ceiling of their garage is properly insulated. Because of the typically humid conditions of a garage, homeowners need to be careful in selecting the type of insulation they choose to use in their garage. Fiberglass batt insulation is prone to moisture damage. Once it has been saturated with moisture, mold grows quickly. Additionally, when the insulation is damp, it is rendered basically useless.

The best solution to addressing humidity in levels above the garage is to install cellulose insulation. Cellulose is resistant to both moisture damage and fire, making it an excellent option to add in your home - especially in spaces that are prone to humid conditions.

Treating Un-insulated Knee Wall Spaces in Cropp, VA

Homeowners in Cropp, VA had trouble cooling their upper floor in the summer. Even with the AC running constantly their upstairs bedrooms wouldn't cool down enough to be comfortable. This home had knee walls in the attic. Knee wall spaces are small spaces commonly found in finished attics beneath the roof rafters. These rooms are most often found in attics with either cathedral or sloped ceilings behind a short wall and come with or without a small door to access the area. These knee walls were insulated with our SilverGlo then completely air sealed to stop air leakages. Without the extreme temperatures and the air leakages, the space is now clean and suitable for storage. The adjacent rooms are more far comfortable and energy efficient.

Project Location: Fredericksburg, VA
We just purchased a home constructed in 2019, and we're finding that it's not as well insulated as we hoped. We're looking to start by insulating the two car garage, which is located on the ground floor and sits under two bedrooms on the second floor. It's causing the two bedrooms to become very hot with the beginning of summer. The drywall is already installed in the garage, and we'd prefer to not take it all down, but we're willing to consider a range of options based on cost.
