Comfenergy Before & After Photos

This Jeffersonton, VA homeowner has suffered from high humidity in the basement of their home for years. The basement is attached to a low ceiling crawl space built on a slab. The high humidity is typically caused by:

1. Drainage of ground water from outside.

2. Hydrostatic water table pressure coming up from below.

3. Hot/humid air coming into the basement and hitting cold surfaces.

These before and after photos show how Comfenergy solved the humidity issue. A perimeter drainage system was installed in the slab around the perimeter of the crawl space. CleanSpace (20 mil) vapor barrier is tucked behind the perimeter drain. Then Thermax foam wall panels are installed to provide the proper air sealing and insulation value. Thermax also provides a thermal barrier for fire protection and meet codes.

Now the basement and crawl space are nice and dry!

This homes attic had old insulation, open access air vents and an attic fan.  This all added up to a lack of control over the space and temperature fluctuations that impacted the comfort for the homeowners in the living spaces below.  We air sealed the attic with ZypFoam, sealed up the vents and fan and used SilverGlo insulation panels to cover many of the walls and other needed spaces in the attic. This will help control the space and reduce the loss of conditioned air from the living spaces below.  Increased comfort and lower bills will be other nice results.  

A homeowner in Brandy Station, VA had inefficient insulation in their attic and they wanted to make their main floor more comfortable. To fix this issue, we removed all of the old yucky insulation, air sealed the attic by closing all penetrations and top plates using polyurethane foam, and then we blew in TruSoft cellulose insulation to an R value of 49. This resulted in a much more comfortable main floor, as much less conditioned air could now escape from the attic.

HVAC ducts likes this one in the attic of this Harpers Ferry WV are designed to deliver conditioned air (heated or cooled) from the HVAC system into the rooms of the home below.  In the summer attic temperatures and reach up to 120 degrees or higher and in the winter attic temperatures can fall well below freezing.  That means the conditioned air could be travelling through a duct that is either baking in the heat or has been sitting in freezing cold temperatures as if it were outside.  These harsh conditions can work against the efforts of the HVAC system and result in the conditioned air being less cool or hot than it needs to be to make the rooms of the home comfortable.  It also causes the HVAC system to run more than it should, running up energy bills.  Encapsulating the ducts in spray foam helps insulate them from being impacted by external temperatures.
