Why it mattersOne room is always cold, the upstairs bakes in summer, ice forms along the roof edge, or the heating bill feels too high for the size of the house. Homeowners want to know whether the attic needs more insulation, how spray foam compares with blown-in, what air sealing does and whether old insulation has to come out first. An insulation contractor that explains this plainly on its own website earns the home assessment. StrideRank writes those articles for your services and your climate and publishes them every week.
