Derek who we discussed the replacement…
Derek who we discussed the replacement of our windows & doors was excellent when letting us know our options. The quality examples was exactly what we were looking for. Can't wait for these to be fitted.
Fab home visit from Derek!!
We had a fab home visit from Derek earlier in the week to give us a quote for new windows and doors. He was really knowledgeable and informative, and gave us ideas we hadn’t even considered but would suit our needs really well. We’d mentioned the importance of bringing in more light to our living space, and he’d kept this in mind from the beginning. He talked us through everything and was never pushy for a sale, however the quote he gave us was amazing and we were really happy with it (and relieved!!) as our budget is tight with a baby on the way. We also like how eco and environmentally friendly this company is, knowing we’ll save on our monthly bills and the windows that are removed will be recycled. We’re looking forward to having our new windows and doors fitted in the new year. Ask for Derek for a very friendly service with lots of laughs!

Excellent visit from Derek
We had a visit from Derek to discuss upgrading our existing double glazing. Derek made us feel at ease, with no pushy sales talk. He explained the products in depth, in simple language which we could understand.
In addition he was most helpful in identifying some windows which windows did not need replacing at the moment. We were most pleased with his suggestions and of course the price.
First class windows and installers Carl and Jordan
Carl and Jordan came to us and were excellent. Our windows were put in with little mess and what little there was they hoovered up before they left each evening. There was little interruption to us and they were so kind to move furniture or whatever needed to carry out the work. The finish is superb inside and out we are thrilled. Would thoroughly recommend GreenCastle.

A great company and quality products
From Marc the surveyor and fitters Cliff and Jordan our experience of Greencastle home improvements has been 100% positive. The Cliff and Jordan did a great job and made sure they cleared up afterwords checking that we were happy with the outcome at every stage. This all complements the high quality product which, now fitted looks brilliant. All of our requirements have been met, windows, front, back and patio doors.
Thanks to all concerned.

Derek from Greencastle Home Improvements came around today to discuss with us options of replacing our windows and front door. Derek was polite, friendly and explained all options thoroughly. We decided to go ahead with replacing the front windows and door just now. We were shown a sample of the window which was good quality. We look forward to making our flat more energy efficient. Thank you to Derek for making the process stress free.
