Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

I recently had my wood flooring installed by this company, and I couldn’t be happier with the results. The team was professional, friendly, and incredibly helpful throughout the whole process. Their workmanship was of a very high standard, and they took great care to ensure everything was completed beautifully. They were always approachable and happy to answer any questions, making the experience smooth and stress-free.

What to ask a Grays extension builder before hiring?

What qualifications and experience do you have as an extension builder in Grays?

An extension builder in Grays should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Grays?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Grays extension builder’s ability to deliver a result that meets your expectations.
