WHAT OUR CUSTOMERS SAY

Well what can I say about bs15 doors.

Well what can I say about bs15 doors. Absolutely 100% would recommend these guys. From ringing them up I had someone come out to my house the next day to measure up who was very friendly and made me feel confident in my decision to go ahead with getting my doors supplied and fitted with this company.

Kelly Palmer

Really really happy with my new front door.

Really really happy with my new front door. Communication with Ruth along the way was very easy and she always replied promptly, and the fitters did a perfect job! The price was the cheapest I got too. Definitely recommend them.

Susie Howells

Smooth communication from initial consultation to final installation.

Smooth communication from initial consultation to final installation. Professional service, reasonable price, definitely recommend. We had our front door, three windows replaced by BS15 Doors, definitely coming back for the rest of windows, thank you!

Han Lynn

Mike Norman

Top service from start to finish.

Top service from start to finish. From measuring up to supply speed and fitting. Ruth and John both excellent throughout. Cheapest quote by a long way in my local area and quickest turnaround to get them fit too. Will definitely use again on my next renovation project.

Louis

Definitely worth getting a quote from them.

The guys who fitted did an excellent job, showing me issues that had been identified earlier and how they have dealt with them. Windows have now been in place for quite a few months now and we have had no issues with them through any of the storms we have recently had.

Colin Gimblett

Fantastic service from start to finish.

They listened to what I needed, made suggestions and generally supported and kept me informed throughout. They turned up when they said the would with a quick efficient team who were in and out in less than 3 hours. New front door, overhead canopy and two windows! Great price too. We had quotes from other firms. But they lacked the customer service and personal youch that BS15doors gave.

A Peters

Great experience from initial enquiry to installation!

Ruth and John delivered a personal and instructive service and the door looks great. The chaps who installed it were friendly, professional and neat and tidy also and to top it all they offer competitive prices and good customer service too. Would recommend.
