"I would hire this company over and over again! Humberto, his son and their guys are amazing! Our bathroom and laundry room had gotten water damage due to a backed up sewer line. Humberto, his son, and their team replaced drywall, baseboards, primed and painted both rooms. They redid the laundry room floors, and the vanity in the bathroom. Everything looks amazing, and we have already discussed with them if they can redo the rest of downstairs, paint upstairs and my kitchen cabinets. They are VERY NEAT workers, always cleaning as they go. They’re reliable, trustworthy and you can tell they aren’t just in it for the money. Humberto is really compassionate."

My focus is to provide a professional and affordable service for all customers based on our expirienced technicians and high quality equipments ready to take care of any drain problem or any emergency 24/7

"I had a clogged toilet that could not be plunged. Jorge and Giovanny were very efficient at identifying the problem and resolving the issue; the clog was not at the toilet level, but rather it ended up being a clogged pipe to the septic. They were both very amicable. I am keeping their card and will call them back for any problem in the future."

"This was my second time using HireHer for a major project. The first was a couple years ago when they totally rebuilt my deck and did a great job. So now when I decided to update my two ensuite bathrooms, after doing my due diligence researching contractors, Hire Her was still my top choice. Angela and her team did a wonderful job with the bathrooms - beautiful new tile floors, vanities, toilets, hanging shelves. Angela is very professional, responsive, and easy to work with, and so are Steve and Jason. Very happy with my bathrooms now."
