I had used this service before and had even referred them to many people as I was pleased with their service. For my next job, the people who came to give me a quote were VERY AGRESSIVE, did not break the costs down, and pressured me to put a deposit down ("you were happy before..."), even though I had not done my 3-quote due diligence. I went ahead with my quotes, and they were NOT competitive. I could not back out, and they pushed ahead with half of the work.
They went to do measurements at a rental apartment when I explicitly told them not to as the tenants were not home and asked for another day. The installer was rude, they used a highly toxic caulking on the inside of the install (making the tenants sick), the blinds were broken on the install, and the job site was not cleaned properly, leaving screws in the driveway. My tenants were very upset with their interactions with this company. My emails to them regarding the issues have gone unanswered.
I will NOT use this company again, I will not refer them, and I will advise against using them to anyone I had previously referred to them.
