We provide full service in house engineering. Whether you require a full set of drawings and site visits or if you decide to send us your drawings, our engineers will make the calculations and provide finalized stamped drawings for your permits. Our installers are trained professionals and will record the torque reading for each screw installed and then submit the torque readings to our engineers. To finalize our process, our engineers review the torque readings and upon their approval will provide a stamped letter to our customers to confirm that the screws were installed correctly. This letter is then to be submitted to the municipality to complete the final inspection process.
