About Us


Here is what our customers have to say about us:

Pro-Line has been trading in West Cornwall for nearly 20 years. After many years of fabricating the 'REHAU' frames for ourselves, we decided to cease manufacturing and once again buy-in our frames from Dessian. I had no hesitation in renewing our friendship and ties with Dessian and have not been disappointed. Bearing in mind our geographical position, being 7 miles from Land's End, some people may think 'why not use someone closer to home.' All I can say is that we enjoy dealing with Belfast. The people are friendly and have a way of making you feel important and our sales representative is also very good and will make a point of sorting out any small issues that arise. Most importantly, all of the frames have always arrived on time. I can honestly not remember one occasion when they didn't all arrive as promised. I would be more than happy to verify any of the above to any prospective customer anywhere in the UK."

John Elsey - Pro-Line Window Company, Penzance

Having switched PVCu supplier in 2012, I have found Dessian to be highly proficient. As a supplier of the REHAU profile, we have been impressed by the quality of the product and the service at Dessian. Our orders are dealt with speedily and accurately and I would have no hesitation in recommending Dessian to another PVCu window business."

Greg Holmes - Trade Frames Direct, Co. Down

As a customer of Dessian from 2011, we have found Dessian to be a valued supplier, offering a quality product alongside quality service."

David Blair - Getty Glass, Co. Down

I have been with Dessian a number of years and have found staff to be extremely helpful and knowledgeable. I would highly recommend Dessian."

Warden Wilson - WJ Wilson, Co. Armagh

Joe Roche Glass and Glazing Ltd would not have developed and progressed to the extent it has over the last 14 years without the help and support of Dessian Products Ltd. It has enabled us to give our customers excellent products and services. It is a pleasure to deal with all staff who are friendly, helpful and most supportive, and will always go that extra mile to deliver a professional service."

Since opening in October last year, Dessian has helped us to grow from strength to strength with great products. Their service and personnel are also second to none. Thank you everyone at Dessian - what a great team and company!"

Dexter Roberts and Mike Deacon - Trade Fitter Rates, Cardiff

Since the change of supplier to Dessian, we are very pleased with the service and quality of the Dessian range and feel that we can now concentrate on growing our business, rather than spend valuable sales time on service calls and the like."

Dave Auston - UK Trade Windows, Surrey

I would like to write a few lines regarding the products and service received by Dessian Products. We have been using Dessian for a number of years now and I would say there has been a good working relationship. The admin side is of a good standard and we get looked after when in need."

DWC Trade Windows Ltd has been a customer of Dessian's for the last 8 years. During this time we have seen and experienced Dessian excel in all areas, their product range has dramatically expanded and continues to grow with demand. As for the service, it really is second to none. Their staff are extremely friendly and always prepared to go the extra mile. We would recommend Dessian to anyone looking to supply to the trade or general public."

Rod Sait - DWC Trade Windows, Bournemouth

We find that the quality of products is very high. We have always found the after-sales service to be very efficient and prompt and the technical support to be of the highest standard. All the office staff are extremely friendly and they all make a point of returning any telephone calls when they say they will, which is very satisfying."

George and Mina Tennant - Dundee Window Centre, Dundee

Cala Homes (West) Ltd have been doing business with Dessian Scotland for a number of years and have found them very competitive in terms of their service and price. The supply and installation contract allows a better product finish and aftersales performance for our customer. I would have no hesitation in recommending Dessian Scotland to others."

It has and continues to be a pleasure dealing with all staff at Dessian, Cumbernauld, who supply our company with PVCu Double Glazing Doors, Windows, Units and Composite Doors.

We have been a customer for many years and will continue into the future as we are more than happy with the excellent service provided with every effort being made to ensure all products are ordered and delivered on time. Customer care is an extremely important element and every step is taken by Dessian staff to ensure we are kept in the picture and any queries etc., dealt with timeously."

Over the last couple of years, we have been using Dessian. They provide good quality products and an excellent customer care service."

I've been using Dessian (Scotland) since I started my own business seven years ago. The products are of the highest quality and the customer service is second to none, providing a professional, efficient service. Having used other suppliers in the past, I definitely would not go anywhere else. I know that they have the same high standards as I do and that I can rely on them to help me make my customers happy."

Frances - Stuart McLaughlin Joiners

We switched our uPVC supplier in early 2012. To date we have found Dessian to be a first class supplier to work with. The quality of the product, delivery, administration and after-sales service is excellent. Dessian is a professional business and we would have no problem recommending them."
