LJ did an awesome job working with me on getting out new house carpet cleaned up. Was even able to do it while me and my family were out of town. Communication was great and he even left me some tips on how to keep the carpets cleaned. I plan on having him back next year for another clean.

I just had my carpets professionally cleaned with Carston Cleaning and I could not be happier with the results. We have not had a cleaning, outside of vacuuming, for almost 5 years, since the day they were installed and after Carston Cleaning was hired, the carpets look like the day the were newly installed!

L.J. For the win! This company is a little more expensive than my last carpet cleaners AND they only take cash or check but I will hire them every time from here on out. My carpets have never looked better (he was able to get tons of stains out that the last guy left) AND the carpets were dry a few hours later which is a big deal. Plus he was able to clean my very cheap polyester rug that I love very much.
Thanks L.J.
