This is how a contractor left the job after realizing he had no idea what he was doing and after collecting over $5,500 from the customer.
This is not an unusual story; it happens everyday.
I came in and did the job right the first time as you can see.
"Your Satisfaction Is My Priority"
Always be cautious when using a new contractor.
Protect yourself by making sure that your contractor is Licensed, Bonded and carries Workmans Comp. Insurance (if you don't and something happens the homeowner is liable)
Do not just take their word for it ask for proof of their credentials. Call the State of Tennessee Board of Contractors to verify. It is well worth the effort.
