Olthoff, John A
Owner
During the reconstruction of the home they were great ,now come the the warranty work to replace a defective window which they replace with another defective window and the wrong style of window which again was defective. I have been trying to get them to replace the window since 2014 2015 2016 2017. I have sent texts to Jason Oltoff several time and to no avail no response. I have also sent texts to the company who contracted who contracted them to do the reconstruction by via text and letter and to no avail no response from them Note: the company which is serv pro has given the approval for them to replace the window and I am still waiting to have the window replaced. Note: this is the third letter that I am sending to the main contractor. Plus they were to suppose to complete the siding end caps which are still not completed looks unfinished. Very unhappy with the response to these issues from both Serv Pro and J A Oltoff company. after all we spent well over $300,000.00 dollars with both of them.
