SuperSeal Report


Our houses leak heat (out in winter, in in summer). Heat transfer occurs when there is temperature difference between inside of the house and outside, through walls, ceilings and even floors. Openings in the building shell (like doors or windows) transfer heat at even higher rate. We can slow the heat transfer by adding insulation or shading or replacing the openings with more efficient ones. Slowing the heat transfer is important because it links directly to the cost of keeping the house temperature at comfortable level. If the house is quickly getting cold in winter, it requires to run the heater at higher temperature and/or for longer time, which means using more energy and therefore at higher energy cost.


In addition to those large heat transfers, there may be tens of small heat transfers (leaks) due to imperfections in building shell sealing or other issues. Some examples of such leaks are displaced or missing insulation, door and window gaps, vents, exhaust fans, chimney stacks, and more. In addition to leaks due to heat transfer, a house may also “leak” power – due to standby devices or inefficient use of appliances. Those leaks, while small, can add up to a significant amount of energy being wasted and are relatively easy to fix.


Our report will identify all leaks, heat and power and you will receive a report in form of a quote to repair them all. The quote is obligation free, in fact, you can use it as a checklist to make the repairs/fixing yourself in your own time. Or you can accept it and our installer will do it for you all in one visit.
