Dependable Home Energy Evaluations in Three Rivers, MA

This homeowner in Three Rivers, MA called us when he wanted to get his crawl space insulation re-done. Our Home Comfort Specialist came to the home and noted that the crawlspace had old, damaged insulation hanging from the ceiling. This fiberglass insulation is ineffective even when it is fully where it is supposed to be -- and this one had obviously been falling and home to pests. Insulation is pulled by gravity away from the sub floor you’re supposed to be insulating. The same cold air under the insulation flows into the space on top of it - rendering the insulation useless. As the insulation gets heavier with moisture content, it falls away from the sub floor even more and can even fall to the floor. Fiberglass batt insulation has paper facing and organic material in the resin used to set the fibers into a batt - both are mold food. Results - mold, smelly insulation that is not providing any insulation value and has sagged or even fallen.

The easiest solution for this problem starts with fully removing the insulation from the crawl space. Fogarty's Home Services removes existing fiberglass batts from crawl spaces. This crawl space was incredibly tight, and insulation has hostile fibers when it’s disturbed. The insulation is very bulky and takes up a tremendous amount of space in trucks and our dumpsters which must be emptied. But it’s necessary to have a healthy home in the end. Result - now the crawl space is ready to be fixed properly. The thermal boundary will be moved to the crawl space walls and vents eliminated. No more nasty fiberglass insulation!

This homeowner in Three Rivers, MA called us hoping that we would be able to help him with his extremely high energy bills. He was using an exorbitant amount of oil to heat his home, despite having a very small home. When our Home Comfort Specialist arrived at the home, he noted that the access to the outside of the home did not have a proper door at the bottom of the stairs, just a bulkhead door at the top. Steps from your basement to the outdoors are convenient, but the (metal) hatch doors that cover them are completely uninsulated and leak lots of air. Cold winter air gets sucked into your home continually in winter. In summer, warm humid air enters the basement and causes condensation on cool floor, wall and duct surfaces. Results - Cold basement, cold floors on first floor, drafts, higher heating fuel costs, condensation in summer, higher electric costs for A/C.

The solution for this issue is relatively simple. Fogarty's Home Services installs proper framing. Then, a new insulated exterior door with weather-stripping and locking knob is installed. Now “inside” the house is inside the door, and “outside” is outside the door, so it doesn’t matter that the hatch door is uninsulated and leaks air. Result - warmer basement and floors over the basement, drier basement in summer, lower fuel and electric costs, less drafts, house easier to heat, more security.

This homeowner in Three Rivers, MA called us looking to improve his house to surprise his significant other. When our Home Comfort Specialist arrived, he noted that there was a lack of sufficient insulation in the attic. Since attics are vented, we should think of them thermally as outside in the winter. In summer because of the suns radiant heat, they are much worse than outside, reaching 130˚ on summer days. Clearly, we need to keep an absolute boundary between our living space and the attic so inside air doesn’t move to the attic in the heating season (convection), and heat doesn’t pass up through our ceilings in winter (conduction), and down from our ceilings in the hot summer (conduction, radiation). To reduce overall air leakage, the attic is the first priority because warm air rises to the top of the house and finds any and all holes to leak out into the cold vented attic and is lost. Holes, gaps and joints include between drywall and framing at the top of walls, around pipes, wires, electric boxes, fixtures, duct, penetrations, ceiling grilles and joints in framing. And the only reason cold air leaks in from the outside at the lower levels of the house, is that warm air leaked out of the top and created a suction at the bottom. Attics are dramatically under-insulated compared to today’s standards. Result - cold drafty rooms downstairs, colder floors, house is harder to heat and keep comfortable, higher fuel and electric bills.

Fogarty's Home Services was able to find a solution to help this customer. The best solution is to seal all the leaks in the attic floor and then insulate it with TruSoft™ cellulose insulation. Adding insulation in an attic without sealing all air leaks first should never be done, because you are burying air leaks and making them impossible to seal later - and insulation DOES NOT STOP air leaks. That’s why we first carefully air seal the many various points where air from your home leaks up into your attic and is lost. We use expanding foam, boards, caulk, and metal flashing and fire caulk around your masonry or metal chimney as appropriate. If necessary, baffles (air chutes) are installed in each rafter bay to keep soffit vents clear and prepare for insulation. Finally, our premium TruSoft™ cellulose insulation is blown to the optimum R-value (typically R60). TruSoft™ will not burn, get moldy, or attract pests. Blown insulation fills all gaps and odd shaped voids, and by filling over framing members, “thermal bridging” is avoided. Results - a warmer, more comfortable, less drafty house that you’ll notice everywhere - even downstairs! House is quieter. Fuel and electric bills are lower.
