Excellent job with many facets
Customer Service
Jamie and his team completed an excellent project on our recently purchased house which included boiler/central heating work, repairing and restoring our floor as well as bringing general decor up to date (plastering/decorating etc) in a timely manor. Whenever something unexpected came up, Jamie made it quick and easy to deal with, the work was high quality and was always responsive to calls/texts/emails. Highly recommend Jamie and will look to use him again in the future. Thanks!

New toilet, retiling and painting
Customer Service
I was very pleased with the service. They turned up on time, worked hard and did a lovely job. Very polite, friendly and tidied up afterwards. Jamie was very helpful and responded promptly to any queries and did a couple of extra things (pulling out polystyrene ceiling and replastering and fitting toilet roll holder) that I thought of later within the original quotation. I would definitely recommend this company.
Central Heating
Customer Service
JLI Building Services were contacted to diagnose and fix faults with our central heating system but over a period of several weeks the work to rectify this was subcontracted to a number of different people. Due to on-going issues we had to instruct a qualified heating engineer who confirmed the new pump recommended and fitted by JLI was totally unsuitable for a property our size and was appalled by the standard of work done. We have subsequently had to pay for another pump to be installed and the system to be correctly re-balanced.
The trader replied (on 23/11/2016)
Dear Customer, Thank you for your recent review and I am very sorry to hear of the problems you have incurred. Unfortunately I am unsure of the job that this review relates to as I have received no complaints or issues from any of my recent customers. Therefore as I am unable to comment on the faults you are mentioning, however I do take customers comments very seriously and would always like to resolve issues especially if JLI Building Services are at fault. If you wish to discuss this matter further please do not hesitate to contact me.
