Our customer located in Ingomar, PA wanted to make their kitchen, sun room and family room more comfortable.  There was a draft from the crawl space underneath the home.  We removed existing insulation, spray foamed the rim joist with closed-cell polyurethane foam insulation to reduce heat loss. We installed a SmartDrain system which is an airtight floor drain (water can go down but air can't come up) the special design sounds an alarm letting you know if there is a plumbing leak while draining the water until you can get the leak fixed. We also did TerraBlock insulation on the floor with drainage matting and 2" Silverglo insulation on sidewalls with the white CleanSpace liner. The end result was more comfortable climate in the rooms above along with eliminating condensation and air leaks.

Heat bill costs - we have had walls and attic insulated but still high heat bills.
Antrim Court in Pittsburgh
Our house has lots of icicles that make me think the attic isn't well insulated. Not sure when it was last done on our home so I'd like someone to have a look. Perhaps it isn't the insulation but something else so I'd like to have someone check it out. I'm happy with Bolster-Dehart for our HVAC work so I'm giving you all a crack at the insulation service. Thanks!

Dewey St in Pittsburgh
Hello, I would like a free estimate at your convenience. My friend Alan Reed recommended your company. He knows Paul Dehart. My name is Joe and my furnace has some condensation near it and keeps shutting off. It seems to get to 64 or 67 degrees and then shuts off but won't get warmer than that even though the thermostat is set much higher. I have done some preliminary problem-solving and am not sure what the problem is.

I have an older home, and the front of the home is not insulated. I feel like the cold air is just pouring in my house. Wondering if you do insulation in homes ??

W Prospect in Pittsburgh
Hi, I think I need to insulate a crawlspace underneath the back half of my house, located directly below my living room, first-floor bathroom and a three-season room/porch on the side of the house off the living room. The three-season room is connected to the living room, but also has its own exterior door with 4 wooden steps leading down to the back patio. The crawlspace is only accessible through a 2-3 ft. tall opening located behind these steps. It's not accessible from inside the house or the basement. I think it may be considered "above grade," since it's at a higher elevation than the basement, but I'm not completely sure. We recently had to tear out the wooden steps and surrounding lattice work, which I think was acting as a poor man's wind break, because as soon as we did, we noticed a drastic decrease in the air temperature inside the house above the crawlspace area. There may be other issues as well, as the house is an old Victorian, but this is probably the biggest. If you are still doing insulation work during the winter, and still offering free estimates, I'd very much like to schedule one at your next available convenience. And, if you do come, I'd be interested in potentially having an energy audit done while you're here, depending on the price. Ideally, it could be included as part of the fee estimate for the crawl space work, for purposes of determining the full extent of work needed to fix all the temperature issues, since, as I said, there may be other contributing factors given the age of the house. My schedule is flexible and just about any time or day can work. Thanks, Joe
