Structural cracks

Lewis was able to visit on a Saturday to advise me on large cracks that had appeared on the back wall of my house.He was very professional yet very approachable and explained everything in simple terms. His report came back promptly. I’d be delighted to recommend him as his service and pricing is exemplary.

Quick & professional service.

A needed a structural engineer & Lewis was helpful, polite & professional. Turned up on time.
The service I had was just what I needed, im having 1 internal non supporting wall knocked down & 1 external supporting wall knocked down & a 4 mtr sliding patio doors fitted. I was given all the correct information back very quickly. I would highly recommend Lewis services.

Excellent Service - Headache gone!

I called Lewis after being let down by no fewer than 3 other structural engineering companies. From the outset he was attentive to my Gabion basket issue and how my problem had manifested. He took the time to understand that I was not a professional and kept this in mind as we discussed possible solutions. After providing him with all the information, he turned around my solution and a comprehensive report in a very short timescale. I was only invoiced after the work was complete and for me that is the mark of a man who is confident in delivering. Thank you Lewis, I hope others read this and garner the same confidence in working with you that I have. Lee Simmonds (Self Builder)
