"Fabulous job on my file floors"

"Great service, vents thoroughly cleaned out with pictures before and after."

"Came the next day. Was right on time. Didn't make a mess. Very nice person."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"I cannot say enough good things about Rich and his crew at Custom Craft Environmental. After having our sump get overwhelmed by 7+ inches of rain, we were lost. Made several calls to "national" water clean up companies with no reason. Rich was at our house 2 hrs after we called and his crew was there the next morning. They were efficient, helpful, knowledgeable, kind, punctual. Price was good and work was excellent. We highly, highly recommend."
