I can't recommend this company & Jon highly enough. We needed urgent sound insulation of ceilings in a basement flat & Jon went out of his way to help with a deadline. He gave explanations of the work carried out, as well as photographs, every day. He also pleasure to deal with. I will definitely use this company again.

I first hired Jonathan and his team to insulate my external wall and window sill. They did an amazing job and were so pleasant to work with that I entrusted them with the sound-proofing of my bedroom ceiling as well. They were always lovely to chat with, on time and cleaned everything afterwards. They really went above and beyond and answered all my many questions. I cannot recommend them enough!

Jon and his team were approachable and tidy. Good communication of each step of the work and did things well.

ESii did a brilliant job. They were very easy to deal with as they replied to emails and phone calls quickly, turned up on time when they said they would and were great at cleaning up during and after the work. I was given several options to choose from with advice on each. Sound transmission is hugely reduced and I am very pleased with the result. I can't recommend them highly enough.

It's been such a positive experience having ESii complete our insulation work, in such a professional manner, so we highly recommend them to anyone requiring thermal or sound insulation work. Our dormer room walls, and surrounding roof spaces, required insulation but we struggled to find any company willing to do the work. Jon contacted us promptly and gave a full appraisal of the work that was needed, a full breakdown of the costings and time required, and quoted us a very fair price. Among the most skilled, friendly and tidy contractors we've ever used so many thanks to Jon & Jason!

Jon was reliable, on time and excellent at communicating what was happening. The installation took place while we were away and Jon sent photos every day he worked to show the progress. His quality of work was outstanding and he left the flat clean afterwards. He charged a reasonable price as per his quote and we look forward to having a warmer living room this winter. We could not recommend ESii and Jon Hook more highly.
