Work Requests From Fairfax, VA
Springmann Dr in Fairfax
Looking to replace attic insulation and attic screens. There has been evidence of rodents in attic.
Park Vista Blvd in Fairfax
Would like an estimate to have our doors and windows air sealed. Recently purchased the house and want to air seal since we will not be replacing windows and doors for a few years.
Gainsborough Dr in Fairfax
Need insulation installed in my attic
Penderview Dr. in Fairfax
Looking to put sound proofing insulation in ceiling so I decrease the amount of noise I hear from my upstairs neighbor. Small condo, 564 sq ft.
Commonwealth Blvd in Fairfax
2 story single family home extremely hot 2nd floor in summer. We just bought and moved into the house in Feb of this year so I'm expecting the house to be frigid in the winter. Attic insulation is subpar and I would expect no sealant in attic either.
Breckinridge Lane in Fairfax
Have AC / heat pump unit in confined space adjacent to loft deck. Unit operation combined with the hot, humid air is causing condensation. This moisture is running down through the wall and collecting in a closet. Mannix representative recommended I insulate the area, then (somehow) cool down and de-humidify the area to stop the condensation. Perhaps just applying the installation will solve the problem. Would like you to stop by, analyze the problem and recommend a solution. Thanks. Tom
Ridgelea Drive in Fairfax
Hi. I am interested in conducting a blower door test and audit to see where air maybe seeping in from outside, as the home is particularly humid, despite our recent installation of an attic fan.
Abington Court in Fairfax
I fell through the ceiling and brought down a bunch of insulation with me. Seems like now is a good time to evaluate the insulation in the attic.
Hamilton Drive in Fairfax
Seal of crawl space and attic.
Looking to insulate a hot attic that also heats the 3rd story of a townhouse.
Autumn Willow DR in Fairfax
The second level of our home stays very warm in the summer time which could be because our heatpump is getting old and is actually in the attric, but at this point, i'm interested in getting your thoughts on whether or not we have proper attic ventilation and/or insulation. I'm interested in possibly having an energy audit to see if we could use better insulation, a radiant barrier, or possibly an attic fan. Looking to get some more information on what you could provide and pricing to go along with that. Thanks in advance.

I have a void space under my garage slab from previous repair work. The void is bounded by the crawlspace wall, the basement wall, and the exterior foundation wall. Seems like injecting that cavity with foam would be a good idea.
