Highly Recommended

We have recently had a few air-con units fitted in our home, after receiving a few different quotes we decided to go with CJS. Their knowledge of the trade is excellent. Colin and Tracy kept us up to date with everything going on from quotation to aftercare. We have even had Colin back to service our boiler and a few other repairs. Thank you for the excellent continuous service. 5***

Boiler Replacement

We have a portfolio of properties. CJS has recently replaced a combi boiler for us, and also carried out services and gas checks to our properties. We have found Colin very polite, efficient, knowledgeable, and easy to work with. He also communicates very well with both us and our tenants. We have found Colin easy to contact and will always return our calls and keep us up to date on the progress of the works. HIs wife Tracy is also very knowledgeable and ready to help. We would not hesitate to recommend CJS.

Great Service!

CJS fitted a new boiler for us, very happy with the price and the service and boiler suggested to us. Colin and Tracey are very knowledgeable and friendly. We have had them back to service the boiler and do other things since. Would thoroughly recommend this local family run business.
