Air Sealing a home is one of the most cost-effective ways to make a home more comfortable and energy-efficient. Air leakage through windows, doors, walls, rim bands, floors and ceilings has been shown to increase heating and cooling costs 35-40%. For the average American home, it's like having a 2' x 2' window open ALL THE TIME!
Unsealed chases and cavities in attics and crawl spaces bring unconditioned and unfiltered air into living areas. Sealing these air leaks will not only make your home more comfortable and energy efficient – it'll improve the quality of the air you breathe.
Our team will examine your entire home, top to bottom, searching for gaps, cracks and holes where outside air infiltrates your home. You may not realize all the places where air can leak into your home – such as electrical outlets and fittings, or gaps around pipes and wires, in addition to the places mentioned above.
As part of the comprehensive energy audit, your energy auditor will do a "blower door test" to de-pressurize your home (don't worry, your windows and fine china are completely safe!) to measure the amount of air infiltration and locate air leaks.
Air sealing must be completed before insulation is installed. Most forms of insulation won't stop air infiltration, so the outside air will simply pass through the insulation, significantly reducing its effectiveness. Never trust a company that will install insulation without sealing air leaks first.
Wherever possible, we use environmentally friendly caulks, foam, insulation board, etc., along with good building science to reduce air infiltration.
Sealing air leaks can help increase your comfort, save energy, and improve your home's safety and durability. But the first step is to schedule an energy assessment to find out exactly what home improvement work is recommended for your home.
We were unaware of what was involved in an energy audit and your audior took the time to explain everything. We were impressed with the report which told us the areas in which we need to take action on. He never pressured us to use any particular contractors, he just suggested that we go to the Building Energy Pros web site to select contractors of our own choice. He did an excellent job and we HIGHLY recommend the Building Energy Pros. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB!
The Building Energy Pros auditor was very knowledgeable. I was VERY HAPPY with him. He promptly E-mailed my energy audit report to me and I will consider all of his recommendations.
We found out that our house really has no energy problems. We are happy to know that we
I was very satisfied with your energy auditor. He was very qualified and spent a great deal of time with me. The energy audit was very informative.
The energy auditor was very good and helpful. He keeps in touch with me to answer any of my questions.
I was very satisfied with my energy audit. The auditor gave me some tips on attic insulation that were very helpful.
I was very satisfied with my energy audit. Thank you!
Very good service! I am going to replace the windows as the auditor had suggested.
I was very happy with the energy audit. THANKS!
My energy audit was very helpful. Joe Dempsey, your auditor, identified some structural problems that I was not aware of and explained to me why I need more insulation.
The auditor was EXCELLENT! He spent ALOT of time with me. I am going to take 3 to 4 of his suggestions and correct these small items to save on my energy bills.
The auditor did a GREAT JOB! He knew a lot about older homes, which we have. The report was very comprehensive. Thank you!
Your energy auditor was very nice and helpful. He answered all of our questions. We will recommend Building Energy Pros to our friends and neighbors.
The auditor did a TERRIFIC JOB! The report was FANTASTIC! I will make all the repairs he suggested. I will definitely recommend him to everyone I know that could benefit from a home energy audit.

The energy auditor was very professional and I am very satisfied with both the energy audit and the report I received. I will be referring the Building Energy Pros.
I was very satisfied with the auditor. He was great and gave me some very valuable information. I will refer him to people I know who may need a home energy audit.
Your home energy audit proved to be very informative and helpful. I was not aware of the updraft created inside our walls because of the balloon framing construction. You said that that can cause heat to be pulled out of the house with the draft going up inside the walls and should be re-mediated. You also said that the attic insulation was insufficient and that fiberglass batts can leave spaces for around the edges causing heat loss and that it should have blown in insulation on top of what was there to seal the whole attic and increase the r factor. After going over your findings and telling me how you would fix the problems you told me how I could do it myself with stuff from the Home Center and for a quarter of the cost. Well, I did. I went into the basement and filled the bottom of the wall joist with unfaced insulation where they set on the sill plate. I then cut one inch foam board the size for each space and set it in and the sealed the edges of that with expanding foam as well as the sill plate to the foundation. I also sealed the sill plate to the foundation where the joist ran along it, as well as the top of those joist where it made contact with the subflooring. Next I went to the home center and rented their blown insulation machine and got ten bales of the insulation. I filled the attic on top of the batt insulation with about six inches giving another r-19 factor on top of the r-19 that was there. You said that the blown in would also help seal the heat loss around the edges of the batt. The work in the basement cost $144.00 and the work in the attic cost $328.00. After the 30% federal energy tax credit it will end up costing me about $330.00, which you said I should recover in savings in the first year. Thank You for all your advice and expertise. You made me aware of things I should consider and did.
