Complete window replacement guide for Joliet homeowners. Best window brands, energy savings, what to expect, and how to choose a contractor in Will County.
Replacing windows in Joliet 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 Joliet.
Joliet homes at a glance
Joliet is the Will County seat and one of the oldest cities in the area, so one job can be a limestone-trimmed foursquare near the Cathedral Area and the next a 2004 two-story off Caton Farm Road. Few towns we work in have that much range in a single zip code.
Many of the older Joliet houses still have original wood double-hungs with rope-and-weight pockets behind the trim. Those pockets are open, uninsulated cavities, so we plan for them at the estimate.
What to choose for your Joliet home
Near downtown, the Cathedral Area and St. Pat's, choose a wood-interior window and a full-frame installation. Original openings have weight pockets and old flashing that should be dealt with, and the trim is part of the character of the house. Double-hungs with a simple grille pattern in the upper sash usually suit these homes best.
On the west side, in the ranches and Cape Cods built in the 1950s and 1960s, a good vinyl or Fibrex window installed as an insert is usually the sensible choice. The frames are sound, the openings are standard and the money is better spent on Low-E glass than on a premium frame. Consider a casement over the kitchen sink, where a double-hung is awkward to reach.
In the far west subdivisions off Caton Farm Road, 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.
A typical window job in Joliet
A common Joliet job is a 1920s house with 18 to 25 original double-hungs, a few of them painted shut. We remove the full frames, insulate the weight pockets, and install wood-interior windows with casing to match. It takes longer than an insert job, and the difference in comfort on the first cold night is large.
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.
