Had 15 windows installed, called for a 3 door estimate, came out Saturday, told me since I was a previous customer we would get a better price. When we were given the price, told the salesman we had to check our finances, his response was the price was only good while he was there and if we didn t sign now we would be treated as a new customer in the future and our price would go up $5000.00. These high pressures tactics don t work and I will never refer anyone to these people again. I am a contractor and we have never used these tactics
