What our clients say

We had a number of company's quote for a 11,000 sq. ft grain store and insulated lean-to (with office mezzanine) in 2019. We liked the service and attention to detail that we received from Mark @ JOHNSTRUCT at that time.  Their price was extremely competitive. Despite the weather trying its best to make life difficult during the ground works in winter 2019/20, the building went up on time and on budget.  JOHNSTRUCT Ltd. installed a large concrete yard area as well as all the drainage. They undertook many extra's and alterations at our request, some quite late in the day..  Even after monsoon weather in May the drainage worked amazingly.  From the building, power floated concrete floors through to the finishing touches and Roller Shutter door guys, we're really pleased with the finished project - completed June 2020.  We would not have any hesitation recommending Mark and the JOHNSTRUCT team for your building etc. and we'll definitely be using them for any projects in the future.

Marriages Farms (Millers and Farmers)

We requested a quotation to re-clad a grain store that Richard put up in 1981! It had succumbed to many years of being battered by the elements and us on the farm! Mark came back to me within a few hours of my query with a copy of the original drawings. Mark provided a detailed quotation (with future proofing options) within a few days.  Great service - as usual...

JT & Sons, Essex.

We had JOHNSTRUCT completely refurbish an old concrete framed barn in January 2019 - They had to lower the internal floor level, put in ducting and new external drainage and finished the whole job to time and on budget.   You would not recognise the building now - it looks brand new. Although Richard sadly passed away during our project we're absolutely certain that he'd be proud of the finished product.  I'm very happy with the service and the end product provided and will be back to see JOHNSTRUCT Ltd. for our next project.

Nigel, Abridge

We have had a number of successful planning applications and buildings supplied and erected by JOHNSTRUCT over the years.  We would like to wish Mark and the team the best of luck in 2020 and beyond.

PT, Essex.
