What you can count on
500 Year Home Mindset
We put 500 years of building knowledge, refined by experts like Joe Lstiburek (The Godfather of Building Science), into action to create the best homes possible with the most up-to-date building materials available so that we can maximize value for our clients.
Atlas Owns the Risk
Atlas takes full responsibility for the work of every subcontractor on behalf of the customer. This means that if a subcontractor makes mistakes, we will make it right regardless of if the subcontractor makes things right with Atlas. We take pride in protecting our clients with thorough vetting as well as absolute follow-through in the realm of responsibility.
Long-View Warranty Mindset
Atlas's warranties last the normal lifespan of materials as opposed to the 1-3 years our competitors offer, meaning that if anything fails prematurely due to an installation or design error, we will fix it rather than try to get off the hook because it was discovered after an arbitrary "x" year time threshold.
We Focus on Every Detail of Every Job
At the end of every job we create a punch list and don't leave until you are happy. We take the time to catch small issues before they become lasting frustrations, making sure the finished work reflects the level of care and detail our clients expect.
