We needed to push down a load-bearing wall, so we called a structural engineer. The service was prompt, professional, and reasonably priced. We would highly recommend them to anyone in need of their services.

I had a great experience working with Bolt Structures. From the beginning they were incredibly helpful and took the time to clearly explain the entire process. Every question I had was answered thoroughly, which made me feel confident and informed throughout.

Although the project took a bit longer than I initially expected the documentation and drawings were absolutely worth the wait - detailed, accurate and exactly what I needed. A special thanks to Zeshan for conducting a site visit, it made a real difference in understanding the scope and ensuring everything was tailored to my requirements.

I would highly recommend Bolt Structures for their professionalism, patience and quality of work!

Really pleased with the service received from Bolt Structures. The turnaround time from the initial onsite to receiving the drawings and calculations was very quick. Communication throughout the process was great and they were quick to get back to me with follow-ups when the council had asked for more information.
Would definitely recommend Bolt Structures for all of your drawing and structural calculation needs!
