"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.
