 Trustindex verifies that the original source of the review is Google. We recently had a front composite door fitted, and the experience was fantastic from start to finish! Tom was incredibly helpful and knowledgeable, guiding us through the options and making sure we chose the perfect door for our home. Drew, who fitted the door, did an outstanding job. His attention to detail and craftsmanship were impeccable. The whole process was smooth, efficient, and the final result looks amazing. We couldn’t be happier with the service from Tru-Plas highly recommend!

 Trustindex verifies that the original source of the review is Google. Had a full set of windows and doors. Karl was brilliant and the process was quick and painless. Anything I noticed wasn't quite how I wanted it with the installation, the guys quickly sorted it and the end result was fantastic. Very happy, great price and would highly recommend.

 Trustindex verifies that the original source of the review is Google. The level of service that we received from Tru-Plas was 1st class! From our telephone enquiry with Ruth in the office, our home visit from Karl and then the 2 lads fitting our new front door was superb. We will (and have already) be recommending Tru-Plas to family and friends for the new windows/doors or conservatory purchases. ⭐️⭐️⭐️⭐️⭐️ from us 👍
