My 4th contract with West Norfolk Glass
Customer Service
Good company and staff. This time a new Solidor front door (W N Glass installed a Solidor side door for me 4 years ago which has given and gives perfect service). Took less than half a day to remove the old timber door and frame and install the new one. Price was competitive and I know should any problems occur they will attend promptly. I once got a quote from a small local firm for Evolution double glazing and they could not match WNG's price. I am certain they could not beat WNG's service. Order with confidence.

A reliable and trust-worthy company
Customer Service
West Norfolk Glass have completed 2 jobs for me: Replacement of all windows and doors in one house in Cambridgeshire. Replacement of roofline and all windows and doors in another house in Norfolk. In both cases all the work was carried out to a high standard at a competitive price , to budget, to the promised time-frame, and with the minimum of inconvenience to the occupants. They were helpful, friendly, efficient and easy to communicate with at all stages of the work from quotation to completion. I have found West Norfolk Glass to be a trustworthy company and I have no hesitation in recommending them to anyone.

Great experience from start to finish
Customer Service
Exceptional experience from start to finish. We had 3 uPVC windows and a new front door fitted which look great. These were to replace some older units that were not very efficient and let in a lot of outside noise. Richard provided us with excellent customer service and product knowledge, he is a really genuine guy who is passionate about his job and always goes the extra mile. The fitters did a great job and the whole experience was smooth and straightforward. Highly recommended.

Poor quality work and materials. Absent quality control.
Customer Service
Replacement windows and doors were part of a house refurbishment. Installation completed on 30/11/21. Remedial work completed July 22, with many visits and revisits in the meantime. Workmanship was poor and careless. Quality control is non-existent. Materials from suppliers are not inspected before being dispatched to the customer. Fitters left with the job "completed" despite glaring defects and did not alert me to the defects. Faults are too numerous to list all of them but here are some examples: Front Door: A warped Solidor was supplied and fitted. Four months and several service visits later it was replaced. The Front door frame, not square and had to be replaced also. Door furniture, a mix of brass and metallic. Original letter box was not square. Because of difficulty in opening and closing the door we avoided using it. Back door: Could not be opened, and if opened, could not be shut when in direct sunlight. Another external door had a 2cm sq hole between the door and the frame because an incorrect base plate (Ali strip?) was fitted. Windows: Poorly fitting internal beading. Rough welds on internal joints than should have been sanded. The only regret I had in refurbishing my house was that I employed WNG.

Window fitting
Customer Service
Helpful firm from start to finish. Fitted 11 windows on schedule and at a competitive price. The fitters were courteous, tidy and did an excellent job.

Patio doors and stable door.
Customer Service
I researched online for a local company - I needed a new front door and patio doors. Salesman, Richard, is extremely personable and most importantly, knowledgeable. He guided me through what was most appropriate for the replacement doors and made useful suggestions. The works were carried out on time and within budget. Aftercare was good too. I had a couple of issues but these were addressed in a timely manner. All in all I would, and have, recommended West Norfolk Glass Ltd to friends and family.

Replacement of some existing windows
Customer Service
This is the first time we have dealt with West Norfolk Glass and have been from beginning to end. From the salesman to the fitters we have been extremely pleased.

Outstanding service and quality materials
Customer Service
We have previously used West Norfolk Glass to replace windows and external doors in part of our house and on this occasion, it was to replace the final window. On both occasions, it was an outstanding service and the quality of the workmanship and materials used is of a high standard. The communication was good and the fitters arrived on time. Having experienced a minor issue with the door hinges becoming marked after 2 years of use, they were replaced free of charge very soon after contacting the company. A good reliable company and value for money. They have a showroom where you can view the products and they offer good evidence-based advice. We would recommend them to any of our family and friends.
