When our furnace needed to be replaced, it was mentioned that we would qualify for some rebates if we had a home inspection done. So clearly this was the time to have it done. The inspection and its results were very interesting. I followed several of the easy to do tips given to improve the efficiency of our home. Replacing at least some of our Victorian era home's original windows had also long been on the radar, so we chose to do several at this time. Upon re-inspection, I was however disappointed to be told that several of the pairs of windows that were closer than 6", only counted as one, when it came to rebate time. I'm sure this was NOT mentioned when given what we could get back per window. Had I known this, I would perhaps have chosen to replace different windows than I did. I have not received my rebate cheque yet at the time of writing this review, but I trust I will, and that this process will have been worth it. It also gives us direction as to where to continue to improve our home as time and budget allows.
