Loft Insulation, Cavity Wall Insulation.

“Dear Sir,

Our bungalow has today been insulated by your firm under the ‘free’ scheme and I just wanted to compliment you on your two workmen who did the work. I don’t know this matters but they were polite and efficient, got on with the job and cleaned up after. I was dreading the ‘mess’ but there was none, we were impressed.”

“Dear Sir/Madam,

I would like to say that I would recommend J&J Crump & Son Ltd to any family and friends who are considering any form of insulation ect to their home.

Your two employees who did the work were polite, friendly and did not leave any form of mess etc. They are a credit to the company. I feel too many people are quick to complain and not enough give praise where its due.”

Mrs Fell

“Dear Sirs

Thank you for the building regulations compliance certificate received yesterday.

Can I just take this opportunity to let you know how pleased I was with the work your two employees carried out for me.

They were lovely young men who were quick and efficient, they took the time to tell me what they were doing and why, they left me with instructions for dealing with all eventualities.

They were an asset to your company – please pass on my thanks to them both.”

They told us exactly what they were going to do, the job was tidy throughout, they cleaned everything after they finished and the new boiler is great. First class job from J&J crump – a pleasure to deal with you.”

Mrs Shearer

Boiler Installation.

“The engineer turned up and didn’t stop all day. We have absolutely no complaints about any aspect of the job, he was a lovely, polite, young man and an absolute credit to J&J Crump & Son Ltd.

Everything worked fine, he showed us how to work the boiler as well. We have to turn the thermostat down much lower than our old one because it’s so warm so we’re sure we’ll save money on our bills.

Just want to say a huge thank you to J&J Crump.”

Mr & Mrs Carne

Services:

Boiler Installation.

“We would like to thank you and everyone who installed the heating for us.
Every room is lovely and warm and the same temperature everywhere, the hot water is a godsend, it’s been about 25 years since we had running hot water. It’s difficult to remember we have no need to boil the kettle every time.
The kindness shown to us by all the team was beyond doing their job.
We cannot thank you all enough.”
