Customer Reviews
Absolutely amazing customer service Neal was helpful and responsive every time we had any queries. This was our first house and with the prospect of major building works I was terrified. There was no need as we were in good hands from start to finish and they went above and beyond for us. Couldn't be happier with how everything turned out and the professionalism that emerald delivered. Would recommend to anyone looking for high quality work and excellent customer service.
Sophie Durose
Very pleased with the workmanship completed by Steve Scott and Lewis, would recommend emerald if you need any home improvements. Area kept nice and clean and fitters are friendly and easy to talk to, and get the job done.
Ray Harlow
Exceptional service from Geordie and William. Ridiculously good and refreshing work ethic and approach to the work that was needed. Very understanding of our family needs(including helping with two escape artist dogs!) and keeping us updated with progress. Old school manners and customer service with very friendly and comfortable way about them. Cannot rate these two highly enough and will gladly recommend them in our area. Thank you.
