About
I'll take each job seriously. No job too small. When I joined US Army I fixed helicopters. Attention to details is a must because lives of people depend on quality work. I carried this attitude to civilian life.

Before initiating the original repair I hired him for, he exhausted all possibilities for the issue and found the solution was something very simple and far less costly. He solved a problem other professionals could not. Very pleased with the result.

Val took on the minor roof repair I had quickly and did the work with no issues and did a quality job! He showed up at my house and did the work when I wasn’t even there…. Easiest work I’ve ever had with a contractor. Will absolutely work with him again. Highly recommend!

We had a great experience with handyman Val addressing 6 issues on our list. He replaced all internals on 2 of our toilets to stop the intermittent running problems and replaced the shutoff valves under the 2 sinks that weren’t working. He also repaired an office chair for us and remounted an outdoor fog light. This was our 2nd experience with this handyman and he completed all the items quickly and with quality. Val is a friendly professional guy and we will continue to hire him in the future and recommend him highly.

Details: 2 - 5 hours (A few different projects) • Repairs • Bathroom • Deck or porch • Plumbing • Lighting • Furniture • Home

Val was great. He arrived early and took his time with replacing belt on my riding lawnmower, finishing earlier than expected. His price was much cheaper than other local sources, and he diagnosed a potential problem on the mower that could be an issue later. I will definitely choose him again, and possibly for other household repairs. Great work!

Details: My home, venue, etc.
