Customer Reviews

Very pleased with my new windows and doors. They look great! William and George did a brilliant job fitting them. Very clean and tidy workers . A great experience from start to finish. Will recommend this company to others.

Grace Grattan

Emerald recently completed a two day job for us. The quality of the windows & door fitted are first rate. Their communications were very good prior to the work, & they rang ahead on the day they were due to start to confirm what was due to be carried out.

They made the procedure from start to finish a smooth one. We would fully recommend them for future use.

Ian Longdon

We had our windows and doors replaced with Emerald Home Improvements. Absolutely first rate service, they worked all day without stopping and made a first class job. I am very happy with the company and the work. This is a very efficient, well run company and I highly recommend them. I have since ordered guttering and fascias. Thank you to everyone at Emerald and especially to Steve and Scott.
