The evidence — in reviewers' own words
Critical
“We made an appointment on Monday to come to the house between 8-9 a.m. on Friday to install a gas line for our new cooktop. Told us he would be there early closer to 8:00 a.m. and he is a NO SHOW!!!!! No call or warning. Why do people not want to work? BE WARNED VERY UNDEPENDABLE! NO WAY TO RUN A BUSINESS DON!”
“***updated review…So this was my previous review when I’ve dealt with him before for the last couple of times I’ve asked him for help. He pretty much ghosted me and says he’s out of town for a month or two so now I wonder if he’s just blowing me off and if he doesn’t want to work anymore. I do live in a mobile home and sometimes people don’t like working on mobile homes. Well, I guess I’ll have to find somebody else …”
Positive
“Came by on time knew his stuff and did a great job. He reworked everything under my kitchen sink and even went above by making sure my pull out faucet weight didn’t need my bungee cord hack. All of this and I didn’t feel over charged. Not to mention he was in and out.”
“Don has been doing our plumbing for years. I wouldn't call anyone else. He friendly, very responsive and most importantly very good at what he does. He recently replaced our water heater and was able to schedule it right away, order good quality parts and got it done at a fair price.”
