John Cunningham
Maximum Impact
I hired John Cunningham DBA Maximum Impact on April 4th 2021 as a Framer contractor for my new house right outside of Denver.
Total contract amount was $50,000
His crew were supposed to start framing mid April.
Per our agreement I paid John 50% upfront of the contract (25k) on April 15th and oh boy was it a big mistake to hand this man any money upfront.
As soon as he received this payment he just disappeared for a month.
After chasing him for four weeks he finally started on the 1st week of May.
Per our agreement framing was suppose to take 1 month and the worst case scenario 6 weeks and I agreed to it, sounded completely reasonable to me.
We expected to be done with frame by mid June and had many other crews lined up for roof, windows, stucco , stone ….. the whole point was to have house closed out and heated before cold fall weather comes in so people can work trough winter in the heated house.
I don’t want to get in all the details about John’s crews disappearing from the job site for weeks at the times, nobody working there and Lumber laying around exposed to the rain and sun and John not picking up the phone not responding to the text messages He just completely ghosted me and my partner.
Non stop lies about people coming tomorrow or after tomorrow. Lies, lies, lies and more lies. Keeping me hostage because i already paid him most of the money up front (what a big mistake).
On July 14th I got my attorney involved and gave John last opportunity to finish job by July 31st
Which the opportunity he ignored and we had to fire him after the due date passed yet again.
The biggest problem we figured out later that John did not use professional people on the job site and they made so many mistakes and screwed up the frame that it cost me a fortune to buy extra lumber to fix it and it was so difficult to find another capable crew who would agreed to fix someone else screw ups.
So to kind of bring it to conclusion,
What John’s involvement with the project brought us.
We lost about 3 months of our time on the schedule side.
Each month it cost to the client (running cost) $5000 a month so total operation losses came somewhere around $15000
Lumber was waisted and reordered at least $10000
Paying other crew to finish and fix John’s screw ups (will not put number on it too embarrassing)
I can not even put a number on how much stress John’s unprofessionalism cost to my self and my wife.
Would highly NOT recommend this person or his company to be hired by anyone in the right mind.
If you still willing to hire him make sure you don’t even show him money until he 100% done.
This person is disgrace to the whole construction industry.
