The "so called professionals were only day labors". No respect for our property. Shoddy work. Not at all happy. Will not recommend to anyone. Gabby, Phil and Brain did their best. We had a sash replaced now we have bugs coming in kitchen cause window will not lock properly. We are hard working folk and for the price you all charged..... Forget about it!!!!

Poor outside trim
The outside trim for the window has poor cuts and the wrong color chalk was used. I have white trim but trap chalk was used

Install communication day of was a little confusing as the installer we originally spoke with knew we did not live in the house. The black on the outside of the window that was ok painted not horrible but not the greatest job.

We appreciate your feedback and apologize for the communication confusion during installation. We'll address this internally to improve our process. We also regret the paint finish wasn't satisfactory and will review our quality control. Thanks for bringing this to our attention.
Experience not as expected or described
Installation was supposed to happen Tuesday around 8 am and I wasn’t contacted to tell me the crew “ghosted” them until I texted the person who said they would be there around 8 am. This was around 9:30.
They came the next day earlier than expected.
I still have a few minor issues which need to be corrected.

First day and happy
Installation team was prompt; Cleaned up well after install. Repaired a screen with a small defect on site. Very happy with outside trim. Sunny side of house is remarkably cooler and much quieter when new windows are closed.
