UKPC Construction is by far the best company I have ever worked with, and I highly recommend them to anyone. Their team is not only courteous and professional but also a breeze to work with. They expertly helped me transform my jungle-like garden, and although I'm writing this review after some time, I'm now looking forward to discussing the extension project they initially designed with me. A big thank you to UKPCC, and I wholeheartedly endorse their services to everyone.

Extensions- 9 Mar 2018
Kenny has just finished building a porch at my address. From the beginning, Kenny has been excellent with regards to providing advice, arranging the job to suit us and providing a very competitive and reasonable quote. Whilst on site, Kenny arrived early, was always extremely polite and the finished job was even better than we imagined it would be. On a scale of 1-10 we would honestly give Kenny an 11 and will definitely use his company again. Would definitely recommend him to others.

Conservatories- 6 Oct 2022
Both Terry and Jason were excellent. They arrived early and the repair to the roof panels as well as the rendering was completed to a very high standard. They were tidy leaving no mess with all rubbish carefully bagged up. Terry has even offered to return to rectify a couple of other minor things he has spotted on the basis of charging just for materials. I would definitely recommend Sandon Oak to others.

What experience do you have with similar extensions in Basildon?

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 Basildon extension builder’s ability to deliver a result that meets your expectations.
