Over 95% of our business is 'retrofit' (going back and re-doing original systems that failed). Over half of these failed systems are less than 10 years old; 30% are less than 3 years old, and many are brand new. Almost all of the failed systems that we replace were originally installed in complete compliance with local building codes, and ALL of them had to pass an inspection. It should come as no surprise that we are often the choice of homeowners; seldom the choice of builders. Usually, for about 15% more than a 'generic' installation, you can have one of our customized systems installed with a 25-Year Guarantee.
