Our Exclusive Triple-Protection Warranty

We believe in the quality of our work and our products, and our warranty proves it.

Money-Back-Badge
Where most other companies only offer a one-year warranty on workmanship, Altera Design offers a full three-years on our workmanship – virtually unmatched in the industry. Since we only work with carefully selected manufacturers, all our products are warrantied for at least one-year or more.

For added protection, as a Diamond Certified company, Altera Design’s work is further backed by a money-back Performance Guarantee provided by the American Ratings Corporation. Between these three layers of protection, we challenge you to find a similar company that guarantees your satisfaction in writing as much as we do.
