Just a short note to say thank you to all the lads who worked on our conservatory, they have done a fantastic job. Once again thanks.

Mr & Mrs Ledgeway, Carlton.

Jason, thanks for our new lean to roof, back door and two windows. A big thank you to Dean for an exceptional job and leaving everywhere so clean. He's a great bloke and we could not have had a better fitter. We will certainly recommend your company.

Mr & Mrs Hobson

Thank you very much for installing my conservatory.

Including everyone who worked on it and who made a very good job.

Mr & Mrs Oldfield, Darfield

Dear Jason, I don’t normally write this type of letter, but on this occasion I think it’s appropriate. I would just like to say a big thank you to everyone involved with the conservatory installation. From the planning and design stage, right through to the final fix, everything went like clockwork. The teams involved in the build were courteous, polite and punctual and above all else, paid great attention to detail. Nothing was too much trouble. They all offered expert advice, gained from experience, on different aspects of the installation which has resulted in a superb usable room. Friends and family have all commented on the quality and workmanship, and both Carol and I are delighted with the job. We would recommend JSS Installations, without reservation, to anyone considering building a conservatory. We wish you all the best, and continued success for the future.

Terry and Carol Beazant

Dear Jason, Please find enclosed a cheque for £4,200.00 on the completion of the conservatory. We are very pleased with the work, one favour I do ask is could we please have the stay hooks for the doors & would it be possible for one of your crew to come & fix same. All the very best to Joanne and new baby & to yourself - Thanking you again

Yours faithfully - Mrs Thwaite

Dear Sir - My husband and I wish to convey our gratitude to Mark and Dave who so conscientiously carried out the work of replacing our front door and three windows with your products last Friday. We were very impressed with the way they worked, wasting no time, and better still, with accuracy and reliability. We shall have no hesitation in recommending you to others who wish to have replacement doors and windows.

Maureen & Russell Firth

No high pressure sales provided with free quotation left to make up our minds. A fast and efficient service by friendly workforce. Highly recommend!!!

Mr & Mrs Vaines at Darfield

The finished conservatory is value for money. Fitted while I was on holiday. Everything left clean and tidy. I would recommend JSS to anyone.

Mr Lockwood at Wombwell

A big thank you to JSS Installations Ltd for work carried out with a conservatory. Right from commencement of the base and brickwork we felt very assured. Wayne worked conscientiously, clean and tidy, a very good job done all round. Followed by John and Dean who did all the installations and during some heavy downpour’s managed a job well done. Not forgetting Tony the electrician and Gary the plasterer for the work carried out by them promptly. To sum up, a well organised operation from start to finish with a polite team. We hope no problems occur but feel confident that should any arise that they will be dealt with in the same manner.

Mr & Mrs Martin
