David Harris – Director – Harris Real Estates

We recently engaged the services of Crucial engineering to quote for servicing a faulty shutter door. We were happy with the quote and subsequently instructed the Company to carry out the work. They attended the site without delay to service the shutter door and to fit a new motor. Not only was the work carried out in a clean and tidy manner, but the advice we were given was invaluable and saved us considerable expense. I can confidently endorse Crucial Engineering and would have no hesitation in recommending them to other landlords.

Allison J Leigh-Operations Manager-Thomis Reed Removals Ltd.

From the initial enquiry regarding installing a roller shutter door into our new premises, to the end product, Crucial Engineering have been a pleasure to work with. The knowledge, and understanding of our requirements made what could have been a difficult situation into one that ran smoothly. The process was relaxed, and the end result is smart, professional and exactly what was needed I will recommend Crucial Engineering in the future and look forward to working with them again on other projects.

Phil Lohan – Director – Brontel Ltd

We requested the services of Crucial Engineering Ltd to carry out servicing and repairs to the automated roller shutters around our building. They responded very quickly to site for a survey and initial consultation. A quote was prepared and a time and date agreed. They were punctual and carried out the works efficiently, accommodating any additional works requested whilst on site. The site was left in a clean and tidy condition. The committee were delighted with the work your team carried out for us. The knowledge and work ethic provided has impressed us immensely and would have no hesitation recommending Crucial Engineering to others Thank you for the great service
