We are so pleased with the results and the whole process of dealing with Cobalt. Every one of the workmen who worked on our house were professional, polite and hardworking. Chris has been instrumental in making sure everything was done to a high standard and in a timely manner. Would definitely recommend Cobalt Carbon Free.

Louise Dale

“Chris and the team were highly professional and have done the most amazing job for us. Due to the age of our property along with previous work that had been done, a few issues were found along the way, but Cobalt were extremely efficient in rectifying these. Within a week we had joists replaced throughout, new insulated flooring, a full damp proof course and more! The team went above and beyond our expectations, I am so happy with how everything has turned out. I would highly recommend the Cobalt team”.

Tim David

“The Cobalt staff were highly professional and worked with us to provide a high quality of work on our project. They were always available to talk to us. The project was on an older house and this threw up some unpredicted issues, but Cobalt were quick to come up with cost effective solutions for us. Overall, we were extremely satisfied with the way the project went and would highly recommend the Cobalt team”.
