This is my second time using Safety King, the specialists that worked at my house were Nick T and Vernon G They were right on time very professional …. introduced themselves as soon as I let them in, they took their shoes off which is very important to me and should be to everyone else, very respectful …and went right to work . Very polite, felt like I’ve known them for years, also I felt very confident and secure with their work. They cleaned all the air duct and my dryer duct/vent and showed me before and after pictures after the job was completed. Very very satisfied with everything.. I look forward to using them again in the future, I’ve already recommended the company to 4 of my friends. Keep up the good work. The only thing I recommend is to wait till the spring time to do it because i had it done February 23. It does get cold inside the house even though they took every precaution to keep the door secured with blankets. But still glad I got it done.
