I wish to express a special "thank you" to Ellie, Paul and Rob. I can also say that both Rob and Paul cleaned up after the job and Ellie always provided a polite, professional and proficient service.

Very helpful, a professional report was done, the guy who came to see my property was on time and polite. He sent me a very detailed report explaining that the problem was condensation not damp, and how we can prevent this in the future. I contacted many other companies, some wanted to charge me for a survey, some didn't turn up and one was rude to me down the phone. I can't stress enough how pleased i was with this company's attitude, I would recommend them to anyone.read more
