Crawl Space Insulation Services In Erving, MA

This homeowner in Erving, MA called us hoping that we would be able to come out and give him an energy evaluation. When our Home Comfort Specialist came out to the house, he noted that the crawl space was extremely humid. High humidity in a crawl space is caused by a number of important conditions that must be addressed such as open vents, leaking groundwater and dirt floors - all which must be fixed otherwise. High humidity causes many problems in the home such as mold (which grows at Relative Humidities [RH] above 75%), rot (which happens above 90% RH) odors, airborne mold spores that aggravate allergies and asthma, increased pests and insects such as termites, and higher air conditioning and heating costs. Since air rises up from the crawl space to the living space, if the crawl space is humid and smelly, so is the upstairs because of it. Once air and water leaks in the crawl space are fixed and the soil is isolated from the earth, an additional measure is needed to ensure the relative humidity stays low at all times, in all seasons. Result - cold floors above, condensation, mold, rot, odors, drafty, uncomfortable home, higher fuel and electric bills.

We had the perfect solution for this homeowner. In this solution, we install a SaniDry™ Sedona in the crawl space to lower the relative humidity in the space. This is combined with other solutions. The SaniDry™ Sedona crawl space air system is a powerful but energy efficient dehumidification and air filtration system in one unit. It’s made specifically for the cooler temperatures found in below grade crawl spaces. Able to remove an incredible 100 pints of water per day and using only 5.9 amps of electricity, the SaniDry™ Sedona drains automatically to a sump or the outside with a condensate pump. It has a powerful 310 cfm blower to circulate the dry air completely around to dry building materials and contents. Mold doesn’t have a chance! An automatic control is easy - set it to 55% RH and forget it - the SaniDry™ Sedona does the rest! And there’s no buckets to empty! Results - Low Relative Humidity, mold stops growing, odors are reduced, crawl space is suitable for storage, lower air conditioning cost, upstairs is dryer.

This homeowner in Erving, MA called us hoping that we would be able to help him. He said that he had very little insulation in his home. Our Home Comfort Specialist evaluated the attic and basement and found that to be true of both, but it was especially true in the basement. Poured concrete basement walls are buried in the cool earth and are perpetually cold - about 17˚F cooler than we like the interior of our homes to be. In the winter the part of the foundation that sticks up above the ground is much colder than that. Heat moves from more to less. The dense concrete has a lot of mass and heat from our basement constantly flows into and through the wall by conduction. In the summer, warm humid air from outside hits the cold basement walls and condensation forms, supporting mold. Results - cold basement, cold floors above the basement, higher fuel bills, more difficult to heat the house.

We had the perfect solution for this customer. In this solution, our Foamax polyisocyanurate (Polyiso) foam insulation board is installed on the basement walls with our proprietary Foam-Tite fasteners. But not just any foam - Foamax polyiso foam has the flame retardant properties to satisfy building codes to leave it exposed in a basement - unlike expanded or extruded polystyrene foam (EPS, XPS). In addition, the Foamax polyiso board has a foil facing to reflect heat so the insulation isn’t doing all the work by itself. Results - warmer, more comfortable basement, warmer floors above basement, less condensation in the summertime, lower fuel bills, house is easier to heat.

This homeowner in Erving, MA called us hoping that we would be able to help him get an energy audit. He needed to know what insulation he had in the attic and basement, and how it was impacting the energy efficiency of his home. We came out to the home and noted that the homeowner had very little insulation in the basement, and there was no insulation in the rim joist. The “rim joist” is the perimeter of the floor framing system along the exterior of the house. The joints and gaps between all the framing members allow for a lot of air leakage into the house. The rim joist is seldom insulated and never air sealed. Basement ceiling insulation, especially fiberglass batts, doesn’t stop the flow of cold air into the home. Results - cold floors, drafty, uncomfortable rooms, cold basement/lower level, higher heating and cooling bills and more condensation in the basement or crawl space in the summer.

We had the perfect solution for this customer. In this solution, two part expanding spray foam is installed on the rim joist and over the sill plate to seal all air leaks from the outside and insulate this important area of the home. Our spray foam has a high insulation value per inch of R7, and because it expands, it seals all cracks and gaps and joints where air from the outside enters the home. Results - warmer floors, less drafts, more comfortable rooms, the house is easier to heat and costs less to heat, less summertime condensation on cold basement surfaces.
