"I have to say that Once and Done did a great job. I had my sump pump fail on a Friday morning around 3AM. I got an alert of a leak in the basement. I put in a request on home advisor not even an hour later and by 7AM on Saturday morning I had a call to discuss the project. Once and Done and their team came out on a Sunday to get the problem fixed. Top notch customer service. Would highly recommend."

"Fast and workers were courteous and competent. Final product looks great. They took the time before the install to review the work to be done. Following the install we inspected the shower and he reviewed the care and cleaning of the surfaces. Grant and Hunter arrived on time as stated and were great to work with throughout the install."

Customers say: Quality work
"My basement bathroom was put in by a do-it-yourself person who did a poor job from beginning to end. If I had a larger budget, the best thing would have been to completely gut it. However, this contractor was able to work issues and created a wonderful space out of a one of the worst bathroom I have ever encountered. In the future we will be installing a window in there . . . but money doesn't grow on trees."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."
