I recently had a major leak to a conservatory which was fitted by Corsham Building Plastics some 9 years ago. Given the warranty was for 10 years I called Corsham Building Plastics. They responded within the hour sending two fitters round to complete the work. No quibbling, no fees. The company honored its warranty. Thank you for amazingly prompt service.

Perfect job. We have a set of beautiful bi-fold doors that are exactly what we specified, ordered and expected. Service, from initial contact through to design, and fitting, was exemplary.

Having extended our kitchen, we planned 6 metre wide Bi-fold doors, 2 large vertical windows and 2 lanterns; all units were made from anthracite grey aluminium. The planning process, with Luke's help, was faultless and he provided a bespoke service. The schedule slipped slightly because of the supply difficulties associated with Covid-19 but this was only to be expected. All units were fitted over a 2-day period by Dean; his work was faultless! Overall, we were very pleased with the process and the finished product is simply outstanding. We are happy to provide CBP with a ringing endorsement.

I used CBP after contacting another company. I received a very professional and perfectionist service throughout from Matt making recommendations for my summerhouse/shed conversion which I went with to the guy who measured up and finally the installers. All were very pleasant and friendly as well as the office staff who checked I was happy with the installation prior to sending the final invoice. I went with black bifold doors and a new door for the installation which was Matt’s suggestion and was happy with the price quoted which beat the other company. They kept me informed of timeframes which they kept to and the price was the same as they quoted for. They were all punctual with the time they arrived for their appointments.

I could not be happier with my new windows. Matt helped us through the selection process and found me exactly what I wanted. The guys who fitted them were very professional. There was no damage to walls. My property was left spotless. They was also very punctual and hard working. I honestly could not be happier. I am having a warm roof conservatory installed at the moment so will review that soon too..

Had new windows and a French door with blinds in between the glass for my garden salon and I’m delighted with the work carried out.

Our experience of CBP has been extremely disappointing. We signed the order in July 2019 with a 6-week lead time but the windows and doors were not fully installed until mid February 2020. Our job was plagued with issues and errors and, because we had some window sections cut away, the house was open to the elements, uninhabitable and could not be re-let to tenants throughout the winter. We ordered 12 windows and 2 doors from the Evolution Spectral range. After weeks of initial delays CBP’s fitters arrived, only to find that every window had marks or chips The whole order was sent back for remanufacture but when the new batch arrived on site there were only 10 windows because CBP had forgotten to order 2 and we had to wait for a third time, making it a 21-week delay in all. We paid two-thirds of the bill, but disputed the final invoice. CBP offered a £2,000 discount which wasn’t a fair reflection of the problems or consequences and then immediately instructed a debt collection agency to begin court proceedings. We made a formal complaint to Which? Trusted Traders who approved our case for the Ombudsman, after which CBP finally agreed a financial settlement. The impact has been exhausting, stressful and financially painful. The paint finish is flaking off the end caps on the window cills already and the whole experience has been a shambles. We feel badly let down all round.

We are very happy with the product and the service provided by CBP, and would definitely recommend them. We had rear patio doors, rear window and side door replaced the door, window and hardware all seem very good quality.

The Supply & Installation of 11 Replacement Windows as per specification for a 200 year old traditional cottage was carried out efficiently and excellently for the agreed price. The Pilkington A-Rated 6.8mm laminated glass units with Argon Gas filled cavities are secure. The wood grain finishing on the pvcu is of a particularly authentic quality.

Five replacement windows installed on time & on budget. Professional approach from everyone we dealt with from start to finish.
