 Trustindex verifies that the original source of the review is Google. We’re coming to the end of our kitchen diner renovation project with Pete and his team and they have been truly amazing!

Pete and Riley are always on time, communicative, friendly, clean and their work is of a high standard.

Even when there have bumps in the road due to other supplier delays/errors, Pete has remained calm and always focused on finding a solution. He is a well rounded tradesman so can put himself to anything, but also has a trusted network of contractors who have also been of a high standard.

Prices are fair and Pete will always consult with you first if there will be an additional cost for any add-ons.

We have really enjoyed having Pete and team onsite and we would use XStream for future building projects.

Photos from the project so far attached.

 Trustindex verifies that the original source of the review is Google. Peter and the team have just finished a loft conversion for us, creating two new bedrooms and a bathroom. Work progressed quickly and the job was completed on time as agreed. Price was competitive and Peter is easy to work with. Really happy with the end result, would use them again in a heartbeat and would highly recommend.

 Trustindex verifies that the original source of the review is Google. We had a roof leak in our summerhouse and 'Xstream build' gave us the best professional advice from the offset, providing us a long term durable solution but giving us the tiles aesthetics we wanted to retain (as well as making good the ceiling inside). A genuinely lovely team, and great finished results! Very pleased.

 Trustindex verifies that the original source of the review is Google. Pete undertook our hip to gable loft extension last year and did an excellent job. He was very easy to have around the house every day and was respectful, clean and great at communicating. Would thoroughly recommend him and his company to anyone.

 Trustindex verifies that the original source of the review is Google. Peter is a top man to deal with. I thought his prices were fair, he was a good clean worker and finished our build on time at the price we were quoted. I would definitely recommend him.
