Complete window replacement guide for New Lenox homeowners. Best window brands, energy savings, what to expect, and how to choose a contractor in Will County.
Replacing windows in New Lenox comes down to three decisions: which kind of installation, which frame material and which glass. The right answers depend on the house, so this guide starts with the homes found in New Lenox.
New Lenox homes at a glance
New Lenox is a few minutes from our Manhattan office. The older part of town near Route 30 and Cedar Road has ranches and split-levels from the 1960s and 1970s, and the rest is mostly 1990s and 2000s subdivisions with larger brick-front two-story homes.
Being this close, we do a lot of repeat work in New Lenox: a front door one year, the windows the next. We keep notes on each house so the second job matches the first.
What to choose for your New Lenox home
In the older part of town near Route 30 and Cedar Road, check the sills before choosing. If the wood is solid, inserts work. If it is soft, plan on full-frame replacement. Fiberglass or Fibrex is a good match here: stable, low maintenance and closer to the look of the original wood windows than white vinyl.
In the subdivisions built through the 1990s and 2000s, you have a lot of windows, so the cost per opening matters. A mid-range Fibrex, fiberglass or quality vinyl line gives the best balance. Do the fogged and rotted units first, keep the product consistent and finish the rest in a second phase if needed.
On the larger lots with custom-built homes, stay in a wood-clad or premium fiberglass line that offers the shapes and sizes the house already has. Mixing a cheaper window into a home of this quality shows. Specialty shapes are long-lead custom orders, so plan the schedule around them.
A typical window job in New Lenox
Typical New Lenox work is 20 to 30 builder windows on a 1990s or 2000s two-story, often with a patio door and a front door added to the same order so the finishes match. Because we are minutes away, small follow-up phases, such as four more windows next spring, are easy to schedule.
Insert or full-frame
An insert window fits inside the existing frame. It is faster and costs less, and the interior trim stays untouched. It only works if the old frame is square and free of rot. A full-frame replacement removes everything down to the rough opening, so the installer can fix hidden damage, insulate the gap properly and flash the opening. It costs more and gives you slightly more glass.
Frame materials
- Vinyl. Lowest cost, no painting, good insulation. Quality varies widely between lines.
- Fibrex and fiberglass. Stronger and more stable than vinyl, with narrower frames and darker color options.
- Wood-clad. Real wood inside, aluminum or fiberglass outside. The best-looking and the most expensive.
We install Andersen, Marvin, Pella and Kolbe. See Andersen vs Pella vs Marvin for how the lines compare.
Glass
Low-E glass with argon fill is the standard for this climate and is what we install by default. Triple-pane adds comfort and quiet and is worth pricing for north-facing rooms and homes near busy roads. Look at the U-factor on the label: lower is better for Illinois winters.
What installation day looks like
The crew covers floors, removes one window at a time, sets and insulates the new one, and trims it inside and out before moving on. Most houses take one to two days. Afterwards we open and lock every window with you and take the old ones away.
