"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"Neil Umphress explained exactly how he would complete the installation of insulation in my attic including the type of material he would use. When a problem was encountered he discussed how it could be handled and left the decision to me. They worked all day with a lunch break Then another problem occurred and I thought they wouldn’t be able to finish in a day, but they pushed through, cleaned up and even insulated an area that was not in the contract just because it needed it. I have more work and will definitely call Neil Umphress to do it."

Insulation questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.
