We carry every leading window manufacturer — vinyl, wood, hybrid, fiberglass — so you get the right window for your home, not whatever the salesman gets paid most to push.
Our certified Home Advisors are trained in building-envelope science, professional inspection, and consumer protection. Diagnosis and education first.
Direct-to-consumer wholesale prices on replacement windows from all major manufacturers.
Strategic partnerships with trusted financial institutions give you direct, personalized access to multiple payment and finance options.
Manufacturer warranties plus our workmanship guarantee. We stand behind the work — no exceptions.
No high-pressure pitches. We diagnose first, then specify the right fix. The job is to help, not push product.
PROCESS
The typical process of buying windows just can’t be trusted. Most companies are built around a sales pitch — we’re built around a diagnosis. Here’s how a Guardian project works.
We evaluate the actual problems you’re trying to solve — drafts, leaks, energy bills, condensation. Sometimes the answer is that you don’t even need new windows.
We discuss the options based on what your home actually needs. We represent every major manufacturer, so we guide you through choosing the right window.
We answer every question you have about how each option performs. We also walk you through your rights as a Wisconsin homeowner so you’re protected from unscrupulous contractors.
Once you’re confident in your choices, we produce a detailed proposal that documents exactly what’s being done, materials used, and exactly what it costs.
Strategic partnerships with trusted financial institutions give you direct, personalized access to multiple payment and finance options.
