The homeonwer living in The Plains, VA was having trouble reducing the humidity in their home all year round. During the comfort and energy evaluation it was found that the humidity source was the dirt floor crawl space allowing the humidity from the Earth to rise through the house.
Comfenergy installed dimple matting, Terra Block floor insulation, CleanSpace 20 mil vapor barrier, and then closed cell spray foam insulation. Now the humidity can be controlled as it is not allowed to enter the home.
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.
This Broad Run, VA homeowner was suffering from cold floors and kitchen cabinets. Upon a full comfort evalution by Carl Depner, he found there to be cold air coming through the back of the home. This cold air would travle beneath the floors above and even into the kitchen cabinets.
Closed cell spray foam was used to perfect the air and thermal boundary to make the floors and kitchen cabinets warm again!
This crawl space in Delaplane, VA was encapsulated using closed cell spray foam. This was done to make the floors above the crawl space warmer in the winter.
This customer had two windows removed in his living room for a new Provia sliding door. He is planning on building a screened in porch this summer.
One of the biggest culprits of heat loss in the winter (and high energy bills) is recessed can lights that back to the attic. The attic is outside the home and the top floor in inside the home. These can lights are 6" holes in the ceiling that allow heated air out of the home. Covering them and sealing them keeps the heated air in longer and lower the usage of the heating system.
This Linden, VA homeowner was hving trouble keeping the top floor cool in the summer. After a thorough comfort evaluation by Comfenergy it was determined that their HVAC ducting system was leaky and poorly insulated. The air coming into the rooms was actually higher than the thermostat setting.
Hard to keep a room 72 if the air you're pumping into it is 85!!!
These before and after pics show what an empty attic looks like with new soffit air baffles installed.....just waiting on fresh, new TruSoft cellulose.
This Midland, VA homeowner was looking to find a way to make the top floor rooms on the back of the house warmer and less drafty in the winter. Upon a full evaluation by Comfenergy, we found the main culprit to be the cantilever on the back side of the house allowing cold air up under the floors on the back side of the house.
Comfenergy opened the rear cantilever to find almost no insulation whatsoever. Plus there were no real rim joists to slow or stop the air from entering beneath the floors above. Comfenergy used SilverGlo foam boards to create a rim joist. We then used closed cell spray foam to air seal and insulate the cantilever.
The rooms on the back side of the house are nice and warm now!
This Flint Hill, VA homeowner always had a cold basement, specifically their laundry area. Presently, it was insulated with loose fiberglass batts pinned to the wall. This neither stops air from traveling into the home, nor provides much of a thermal barrier. The rim joists at the top of the wall were also merely insulated with fiberglass batts.
Comfenergy put together a solution that was effective, and appealing to the eye! The fiberglass was removed and disposed of. Thermax (polyisocyanurate) boards were attached to the walls, with foam and tape sealing the gaps. Then, the rim joists were sprayed with closed cell spray foam to air seal and insulate them too.
Now the homeowner can perform laundry duties no matter what time of year it is!!!
This Middletown, VA homeonwer was complaining that their top floor was cold and drafty in the winter. Upon a full comfort and energy evaluation by Comfenergy, we determined one of the issues to be leaky can lights in the ceiling. Each can light is merely a 6" diameter hole that allows heated air to escape, and cold drafts in during the winter.
Rock wool can light covers lessen this leakage and also provide a necessary thermal and ignition barrier from the hot can light to protect against the possibility of fires.
This before and after shoto series shows a vertical wall adjacent to an attic. Poorly insulated walls like this can allow hot air from the attic to radiate through the drywall and heat the room on the other side. Closed cell spray foam keeps the heat away from the wall and protects it from heating the room on the other side!!
This Boston, VA homeowner had issues staying warm in the winter and cool in the summer. A FREE comfort evaluation by Comfenergy revealed, among other things, an HVAC ducting system located in the attic that was both leaky and not insulated. The hot air was leaking into the attic in the winter. The cold air was becoming re-heated in the summer. Not only was this causing discomfort, but it was making their utility bills go literally through the roof!!
Comfenergy encapsulated the attic ducting system to seal it from those air leaks. This keeps all of their air in the home! It also insulates the air travelling through the ducting system so that it comes out of the vents at the right temperature to stay comfortable.
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!
