The customer called s because they had a condensation problem with the ducts in their 1st floor town house family room. This home, typical of many town homes in Ashburn, with a 2 car garage to the front of the home, and a family room tucked behind it.
The problem was a clear air pathway from the space over the garage to the cold ducts in the ceiling above the family room. We had to seal the rim joist to the exterior, and create an air barrier with silverglo foam block between the garage and the family room.
The results were instantaneous, and this Ashburn home owner now has a house that is air sealed and does not sweat.
The homeowner in Ashburn called, as last year their pipes froze and they did not want that to happy again.This home i has always had issues with hot and cold spots, and freezing pipes in the winter. We found cold air in the master bedroom attic to be getting around the batt insulation leading to the bathroom above. This entire neighborhood of as notorious drafts and hot/cold spots. These homes have also dealt with many frozen water lines. The water lines were freezing almost 20 feet from the exterior of the home! Comfenergy installed 4" thick SilverGlo foam boards with heat reflective barrier on the attic walls.
Problem solved!!! Foam board insulation in an attic keeps the cold air from travelling beneath the bathroom tub and the pipes from freezing.
The homeowner will be more comfortable in the Summer and Winter.....but it lessened the draftiness of the home, and the pipes don't freeze any more!!!
This Ashburn, VA had rooms over the garage that were too hot in the summer. This is can often be caused by fiberglass batts installed by the builder in the ceiling of the garage. They fall away from the sub-flooring depleting all thermal insulating value. This customer decided to remove the entire garage ceiling and use closed cell spray foam to fix the problem.
A homeowner in Sterling, VA called as their house was hot in the summer and cold in the winter and wanted to make their home more comfortable all year. We air sealed the attic floor with one part foam spray, then installed attic decking on the floor with plywood. We created plywood "dams" to keep the future cellulose insulation in place and off of the attic floor decking. Finally, we created an attic hatch cover that was made o 4" thick SilverGlo foam boards, and blew in TruSoft cellulose insulation throughout. The result the homeowmer will be warmer in the winter and cooler in the summer.
Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or cool...it will NOT work!
See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!! This might have been the worst we have ever seen...Might be 2-3 feet of a gap!
Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable!
