Trusted by Infinity by Marvin
Marvin doesn't hand the Infinity name to just anyone. Choosing the right contractor is what separates a product that performs as engineered from one that doesn't, which is why Infinity by Marvin selected Custom Exteriors Inc. as their trusted dealer for the Bay Area. Decades of hands-on experience with Bay Area homes, proven installation practices, and deep product expertise made Custom Exteriors the partner Marvin trusts to represent the Infinity line, from fiberglass entry doors to windows and siding. Our local team of remodeling experts understands how these materials behave in our climate and installs every system with the precision and attention to detail Marvin's standards require, the same standards that make for a smoother remodeling experience and an exterior upgrade homeowners can count on for years.
That standard shows up in the details Marvin looks for in a dealer: installing the appropriate weather barrier to protect energy efficiency and the building envelope, and meticulously aligning seams and applying caulking for a clean, long-lasting finish. It's this level of craftsmanship, handled by trained experts on every single project, that earned Custom Exteriors its place as a Marvin-selected dealer, and that ensures your window, siding, or door delivers the long-term durability Infinity is known for.

Where does Infinity rank among window options in California?
There's no single, independent authority that ranks window brands #1 for energy efficiency, industry-wide. ENERGY STAR certifies products against regional performance thresholds rather than ranking brands against each other, and NFRC ratings are issued per product configuration, not per manufacturer. Any claim that one brand is definitively "the best" in the industry should be treated with the same skepticism you'd apply to any unverified marketing claim, including ones from Infinity's own materials.
What is verifiable: Infinity's Ultrex fiberglass construction meets ENERGY STAR criteria and is available in glass packages engineered for California's Title 24 code, which is the actual regulatory bar every window installed in the state has to clear. Fiberglass as a category has a documented, independently understood advantage over vinyl in dimensional stability, which is the property that protects efficiency over the long term rather than just at installation. Custom Exteriors chose Infinity as the only window line we install after nearly three decades of comparing products for Bay Area homes, not because it wins every published spec sheet, but because of how it holds up over the years we've been installing and servicing it.
