"HIGHLY RECOMMEND! Did much research on companies 1st b/c I was aware of scams with duct cleaning. But this company is very legitimate professional - techs and receptionist, all the way around! Top quality service! On time and will answer any questions and explain it all in great detail? very polite and professional. And yes, they will take photos throughout if you want to see exactly the differences of before and after. I had bought a 1959 home which had never been cleaned. See my before/after photos. Before, I kept having to wipe off my counter tops a few times a day because they always felt gritty. After the duct cleaning, they stay clean now - A HUGE DIFFERENCE! The guys were awesome and went above and beyond by also helping me carry a heavy appliance from upstairs to my basement. Very nice guys! They cleaned up any mess before leaving, like they had never there. You will not regret using their service. Lower Price than others too! Thanks Danny & Cameron! Great Work!"

"No matter what problem you have, Clint is the man for the job! He not only fixed the plumbing issues I discovered during a remodel but was able to fix the electrical issues, flooring problems, install the cabinets, cut and grout backsplash tile, and fix a handful of minor issues that came up along the way. Clint is on time, dependable, courteous and respectful of your property - he even cleans up afterwards! I could not have completed this project without Clint Hatcher and highly recommend him to anyone who needs work done - you will not be disappointed!!"
