Installed windows gutters and flashing around my house. The windows and gutters were improperly installed and it started leaking in my house around the gutters and windows It rained in my house and they haven't been back out to honor the work or lifetime guarantee. They tried to blame it on my siding saying it was faulty. I've been here 14 years it has never leaked. I've 've spoken with the owner Tony, Service manager nico, the sales man Jeff and its been 1 month and they haven't fixed the Windows that I spent around 20,000 on. Not to mention they are expensive and sub contract the work. They were also supposed to replace the cap on the parapet wall and used aluminum fascia and soffit to replace the parapet coping cap.
