Yes. The manufacturer covers the window unit, and Nail Force covers the installation with a written workmanship warranty. That means the flashing, the foam, the sealing and the trim work are on us. The details are spelled out in writing so there’s no guessing later.

Fog between the panes means the seal on the insulated glass has failed and moist air has gotten inside. It won’t wipe off because it’s not on a surface you can reach. Once that seal goes, the glass isn’t insulating the way it was built to. Replacing the window is the reliable fix, and we’ll check every window in your Fair Lawn home to see which seals have failed.

The steps that matter most are the ones you can’t see later: flashing, a sill pan under the window, low-expansion foam in the gap, and sealant inside and out. We do all of them, cap the outside trim in aluminum or PVC, and finish with cleanup and a walkthrough. Your install is covered by our written workmanship warranty.

Most of the benefit comes from two things: the glass and the install. Low-E coatings, argon fill, and double or triple pane glass help the window hold back heat and cold. Low-expansion foam and sealing inside and out stop air from sneaking around the frame. We’ll show you the glass options during your free estimate.

A double-hung window has two sashes that both slide up and down. It’s the most common style in New Jersey homes. Many newer double-hungs tilt in so you can clean the outside glass from inside the house. We install them from ProVia, Andersen, Pella and Marvin.
