Mr Butcher

Very swift and clean job. We are very pleased with the result and all staff were friendly, efficient and professional in their approach to the job. We would not hesitate to recommend Karnheath to others.

Had my loft insulated and boarded out — really happy with the whole experience. Alex was great with communication over email, super quick to reply and answer all my questions. Mick and Micky did the work and were lovely to have around — friendly, tidy and professional. The job was done on time, and they kept me updated on any tricky bits along the way. Would 100% recommend these guys!

I would like to inform you that I found the workmen who did the job very pleasant & courteous & I was completely satisfied with their work.

Mr R Dickson​

Your firm recently insulated my loft, and I would like to thank you for the efficient way it was carried out. The workman who carried out the operation was called John and he was certainly a credit to your firm. He was courteous and polite, and did the insulation work with a minimum of disturbance to us, left no mess at all, which in itself is unusual. Both myself and my wife were very impressed with his attitude, and would recommend your firm to anyone.​

The job was carried out efficiently by two really skilled, helpful and considerate technicians. The job was done without issued and everything was tidied up afterwards. It was also really easy to deal with the Karnheath office to make all of the arrangements.

Had Karnheath Ltd taking out old loft insulation today and replacing with new insulation. Micky and Adam worked very Quickly and did a good job. They showed me photos of the finished article as well. Thank you lads. Also, Lilly on the phone was very helpful, explaining the procedures and she called me to say she had called the skip company to get the skip removed today. Thank you Karnheath Ltd.

Mrs E Gray

I would like you to know how very pleased and satisfied I am with the work your men did in my home. Everything was done so quickly making the place a lot warmer. They were two very nice pleasant chaps and I am very grateful to them, they worked very quickly and quietly, my grateful thanks to you all.

D Patterson

I spent most of my working life in the construction industry, and was initially circumspect about getting this work done at all. However the work badly needed doing and took a leap of faith in employing Karnheath (who I had no previous knowledge of) to carry out the work. From the outset they were a pleasure to deal with. They always arrived at the time and on the date agreed. The works were professionally carried out to a high standard to my entire satisfaction at a reasonable cost. I would have no hesitation in recommending this company to carry out any works within their stated remit.’

Bob Muxworthy, Gosforth

We’ve received a text from our tenant this morning advising the house feels much warmer, thank you

Derek Atkinson, Washington

Our house feels warmer already!

Chris Brummitt, Brummitt Architects

From the initial quote to installation, Karnheath are professional, efficient and thorough. I have no hesitation recommending them.

Rachel Keepin, Gateshead

Amazing communication with the office team, friendly and approachable, work was completed effectively and quicky to a high standard.
