I was needing a front door and Derek came up to give me a quote. He was very knowledgeable and made me feel at ease (I am a female living alone). He went through all the options of the front door and I never felt pressured. He gave me a great price and also gave me finance options. He was also very polite and chatty
No pressure experience
Fast, straightforward service, everything explained well happy with the experience, no pressure from Derek regarding purchase of windows, done and dusted within an hour
Composite door
Friendly, knowledgeable, helpful and informative salesperson. Excellent looking product and a wide choice

Derek
Derek, arrived this afternoon to give me a quote for some work that I was needing done, after a chat and checking wither my request can be done, everything sorted, just waiting the on the survey to be done now, then good to go. Will give an update when job is completed. Derek was very pleasant and no pressure at any point, and took his time explaining everything from the start to finish. Looking forward to getting the job done.

Had Derek and Aaron come to the door to get a quote for windows and doors, both very professional and friendly. They couldn’t do enough and came up with great ideas. Very happy with the quote and the whole process, no pushy sales. Signed up to financial deal, and look forward to getting new windows and doors. They were a joy to have in the house. Thanks Again for everything.

Thanks Derek & Aaron!
Very happy with the experience in arranging the purchase of my new front door through Greencastle. I had Derek and Aaron out to visit me, run through the options and measure up. Derek was great at going the extra mile to answer my questions and make sure my new door would meet my needs. Both were very professional and friendly throughout. I would recommend Greencastle to others. Thanks guys!
