What Installers Say

Built on Trust

★★★★★

Right Angle Engineering is super easy to work with, extremely responsive, and super fast. We have always had to wait several business days for stamps to come back with other engineering companies, so Right Angle has been a lifesaver.

Collin Swainston

Solar Installer

★★★★★

Right Angle Engineering has exceeded our expectations with their turnaround time, always gets back to us quickly if we have any questions, and is a tremendous partner in navigating challenging building departments.

Daren Griffith

Project Manager

★★★★★

The pricing was a great value. I passed both the county and utility inspections with no modifications required. I specifically appreciated the timeliness and helpfulness of Gavin and Ian. Will DEFINITELY recommend them.
