Keystone Window of Pennsylvania

Keystone Window of Pennsylvania brings a much needed change to this industry. Save $50 Off Our Warmest Window. Our pricing is always up front, guaranteed, and includes full installation. If a company wants you to 'buy' today, RUN. There is too much stress in everyday life to have to be bait n switched, haggled and pressured during a meeting. I personally guarantee the replacement Windows/Doors my company sells, and the quality of workmanship that goes into both the window and the installation. We will always sell state-of-the-art, top quality windows and doors. Our customers "MEAN" something to us. More

What is this?

What is this?

We display two types of written homeowner feedback on GuildQuality member profile pages: Comments and Reviews.


In response to our customer satisfaction surveys, homeowners share lots of comments about construction quality, communication, or any other question asked in the survey. Guildmembers can selectively publish these comments here on their profile page.


Reviews are different than comments. These are star ratings that homeowners ask us to publish, and they come with a written description of the type of experience they had working with their contractor. We publish all of the reviews we receive: positive and negative alike.
