Brands We Repair
A premium wood window was built to be serviced, not swapped. Whether it says Marvin, Pella, Andersen, or a name that no longer exists on the spacer bar, we repair it at the component level — typically about 80% less than replacement.
Why the name on your window changes how we fix it
Every manufacturer builds a wood window differently. Marvin's clad-wood transitions, Pella's integrated screen systems, Andersen's balance hardware, Loewen's Douglas Fir sections — each has its own construction logic, and therefore its own characteristic failures. A repair company that knows those patterns diagnoses in minutes what a generalist guesses at. That's why we organize this part of the site by brand: after 8+ years working on wood windows across Montclair, Glen Ridge, Millburn, Summit, Morristown, and our home base of West Caldwell, we know where each maker's windows tend to fail — and how to fix exactly that.
The second thing these brands share: they're worth saving. A Marvin Ultimate or Pella Architect Series unit was a four-figure window when it went in. The wood in it is usually excellent; what fails is a component — a rotted bottom rail, a fogged glass unit, a discontinued crank. Replacing the whole window because one part failed is like replacing a car over a dead battery. Component-level repair costs about 80% less, and it's backed by our 5-year workmanship warranty and a fully insured crew.
And a worry we can retire right away: a proper repair does not void what remains of the manufacturer's warranty on other components — and most of the windows we're asked about are past their warranty age anyway, which is exactly when repair becomes the smart move.
Start with your manufacturer.
Marvin
Ultimate and Signature wood and clad-wood units — superb joinery whose clad-to-wood transitions hide moisture. We find it, rebuild it, and keep the window.
Read the Marvin repair guide →Pella
Architect and Reserve series wood, plus the 1980s–90s casements whose hardware left the catalog. The brand we repair more than any other except Marvin.
Read the Pella repair guide →Andersen
400 Series, Woodwright, E-Series, and older Narroline units — balances, gaskets, and sash corners typically fail decades before the wood does.

Look for a name etched in a corner of the glass, stamped on the hardware, or printed on the spacer between the panes. If there's nothing, text a photo to (973) 564-0958 — we identify most brands on sight and answer the same day. From there it's the usual path: onsite assessment within 1–2 days, repair completed within 1–2 weeks. If your window's problem is generic rather than brand-specific, start from wood window repair, rotten window frame repair, or window sash repair instead — the fix is the same craft either way.
Whatever the badge says —
send the photo.
We'll identify the brand, name the failed component, and price the repair the same day. Free, honest, and usually about 80% less than the replacement quote.
