"Scott arrived punctually for our first meeting and thoughtfully and thoroughly analyzed our problem (mold on peak of cathedral ceiling).  He listened carefully to our thoughts and explained his analysis clearly and completely.  He provided us with examples of similar situations he had addressed, successfully, in the past. He also showed us photos of his previous work. He spent over an hour with us, answering all questions and outlining his processes.  

After we agreed to have him do the job, he provided an extensive written contract for the work.  Our lawyer reviewed the contract and made several suggestions.  Scott quickly adjusted the contract to address our lawyer's concerns.  He scheduled the work promptly and it was completed in the agreed upon time frame.  We asked for the new electrical circuit to be labelled, and Scott took care of this without additional reminders, although I don't believe this was part of his usual service. There were no add ons to the bill.

After the work, Scott responded to questions and promised referrals to mold remediation services if required.  We've called him several times with questions, and he has always responded promptly with useful answers.

We have been totally satisfied with Scott Knapp and Rfactor from start to finish and would recommend him enthusiastically and without reservation to anyone with a similar problem."

NYS Licensed Home Inspector. 30 years experience in building and construction trades. Buying a home is a major investment. Having a home inspection only makes good sense. I will inspect your home from top to bottom and give you a full written report the day of the inspection. Many people look at a home in the perspective of buying. I look at the home in a symptomatic way. There are sometimes tell tale signs of unseen issues that I can catch that the average viewer may not anticipate as much of a problem until it's too late. I will call it as I see it. I am not in the business of trying to degrade a person's home only to inform the buyer or seller of facts.

Energy Efficiency Auditing FAQs, answered by experts

Yes, advising on models that save electricity and reduce utility bills.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Yes, including optimizing settings and suggesting upgrades if needed.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
