Good product, HORRIBLE service! I had security film installed on my windows last year but have been waiting over a year to have the windows caulked. Installer came a few weeks ago to finish the caulking and didn't bring enough caulk! Now I have to wait a few more weeks for them to come back and finally finish the job. You'd think since this job has been on their books for so long they would make it a priority to get it done but now that they have my money I get to hurry up and wait. I would absolutely not use this company again.
