Exhaust Piper Repair in Saint Charles, MO Eliminates Fire Hazard

Exhaust Piper Repair in Saint Charles, MO Eliminates Fire Hazard Exhaust Piper Repair in Saint Charles, MO Eliminates Fire Hazard

Exhaust pipes from furnaces, water heaters or fireplaces are referred to as "hot pipes." Why? The exhaust fumes/air traveling through these metal pipes are HOT! Dr. Energy Saver St. Louis often finds these hot exhaust pipes surrounded by blown insulation in attics. The blown insulation touching the pipes is often blackened from the heat exposure. Dr. Energy Saver creates a block to this blown insulation, and also seals any air gaps around the pipes. Without this, there's a serious fire hazard!

The detail between the foundation wall, the sill plate, the rim joist, and the sub flooring allows for significant air leakage from the outside...especially when pipe wire penetrations are added. It is also this rim joist area that is often poorly insulated. Even when your rim joist is insulated with fiberglass bats, the outside air will still leak in through the bats, because this form of insulation acts as a filter. Spraying expanding foam insulation on the inside surface of the rim joist, to cover the sill plate down to the top of the basement wall, not only seals all air leaks very effectively, but it insulates as well.

Air sealing and attic insulation in the Knee Wall of this St. Peters, MO home included: three inches of spray foam insulation to stop air transfer and achieve an R-18.

Before we arrived, the knee wall was insulated with only a piece of batt insulation---and without proper air sealing, batt insulation in an attic acts very similarly to a filter in a HVAC system...air passes right through it!

Job Stories From Saint Charles, MO
Providing More Comfort in St. Peters, MO

Matt found his home to be very uncomfortable.  He wanted to get this under control so he called Dr. Energy Saver St. Louis.  They came to Matt's house and performed a Home Energy Audit.  The Certified Building Anaylst looked at the home and found that Matt was losing air through his attic.  Dr. Energy Saver air sealed the attic to stop exfiltration of conditioned air into the attic.  Then they filled the attic with blow loose-fill cellulose insulation to improve the thermal boundary between the two spaces.  Now, thanks to Dr. Energy Saver St. Louis, Matt's home is much more comfortable.

Sustaining Heat in Wentzville, MO Basement

James and Betty were unhappy with the coldness and their basement, especially in the winter.  They planned to live in this house forever, but decided that they didn't want to live with this problem forever.  Dr. Energy Saver came to their home and saved their basement by sealing it with spray foam.  Now the basement is a perfect temperature year round.

Air Sealing in Saint Charles, MO

Michel lived in his house for 35 years with his wife and two sons.  He noticed that one room in his house would become drafty during the winter and hot in the summer.  He wasn’t happy with the comfort level in his house and was worried about the musty odor that was developing because of this constant problem.  Michel wanted the comfort level in his home to be perfect so he called Dr. Energy Saver.  After checking out the entire house, the contractor told him that air was escaping his house from the attic and that he had the best solution to fix his issue.  Dr. Energy saver then installed several devices in the home to make sure the air wouldn’t escape and that the quality of air would improve indoors.  Michel is thankful for the job that was done and now lives comfortably.

On really hot days, our AC cannot keep up. We have it set at 72 but it will be 76 in the house. The air coming out of the AC is cool and the unit itself is only 6 years old. We checked the attic and there is no insulation over the garage and only a few inches over the house.
