Window Replacement in South Beloit, IL
Most people don’t plan to replace their windows. It happens after one too many small hassles. A sash sticks every time the weather turns humid. A lock no longer catches. There’s a fog between the panes you’ve stopped noticing, and the frames look rough around the edges no matter how often you touch up the paint.
Wilco provides window replacement for South Beloit homeowners with energy-efficient vinyl and fiberglass replacement windows. Our installers measure each opening on its own, set every new window square so it moves and locks smoothly, and seal the full perimeter before finishing the trim inside and out.
That attention to fit and sealing is what makes new windows stop drafts, operate easily, and keep your home comfortable. See our window replacement page for more on materials and glass.
What We Hear From Homeowners
These are the issues we see most often when homeowners call us about replacement windows:
Drafts Around the Frame Cold air slips through near the sash, even with the window closed.
Fog Between the Panes A haze trapped inside the glass means the seal has broken down.
Windows That Stick The sash binds or takes a hard push to open or close.
Difficult Locks The latch won’t line up or no longer holds the window tight.
Deteriorating Frames Soft wood, cracked vinyl, or peeling paint point to a failing frame.
Windows That Won’t Stay Open Worn balances let the sash slide down on its own.
A properly installed replacement window fixes these issues together. Because it’s sized for the opening and sealed around its edges, drafts stop and the space near the glass feels comfortable again. The sashes glide and lock with little effort, energy-efficient glass helps rooms hold a steady temperature, and new frames give the exterior a cleaner look.
Replacement Window Options for Your Home
South Beloit has a mix of older homes and newer construction, and the right window depends on the house and the room. Wilco installs energy-efficient vinyl and fiberglass replacement windows, and we’ll walk you through the choices in plain terms during your estimate.
Double-Hung Replacement Windows
Open the bottom sash for a breeze, the top to release warm air, or both. A good fit for most rooms, with tilt-in sashes that make cleaning simple.
Sliding Replacement Windows
Sliders move side to side, so there’s no lifting. They’re practical over counters, in basements, and in openings that are wider than they are tall.
Picture Windows
A fixed pane that brings in plenty of light and keeps the view clear. Add operating windows beside it if the room needs ventilation.
Custom-Fit Replacement Windows
Existing openings often aren’t a perfect standard size. We measure each one and order windows to fit, so they seal tightly and look finished.
Vinyl or Fiberglass
Vinyl is affordable and needs very little upkeep. Fiberglass costs more but holds its shape through temperature swings. We’ll explain the tradeoffs.
What to Expect During Window Replacement
We keep the process simple and make sure you know what’s happening at each step.
Free Consultation and Estimate
We come to your home, ask what’s bothering you, and look at the windows. The estimate costs nothing.
Evaluating Your Existing Windows
We check how each window operates and inspect seals, frames, and trim, then explain which ones need replacing.
Choosing Your Replacement Windows
We help you pick styles, materials, and glass, measure each opening, and provide a written quote.
Preparing for Installation
When your windows arrive, we set a date and let you know what to move.
Replacement Window Installation
Our crew removes each old window, preps the opening, and installs, seals, and trims the new one. We’ll show you any hidden damage first.
Cleanup and Final Walkthrough
We haul away the old windows, clean up, and test every new window with you.
Many window replacement projects are finished in a day or two. Larger homes or jobs with framing repairs can take longer, and we’ll give you a realistic timeline up front.
Residential Roofing in South Beloit, IL
Wilco Exteriors also provides residential roofing for South Beloit homeowners, including roof inspections, repairs, roof replacement, and new roof installation.
Homeowners often contact our roofers after finding shingles in the grass, a stain on the ceiling, or flashing lifting around a chimney or vent. Northern Illinois snow, ice, thunderstorms, hail, and freeze-thaw cycles wear on a roof over time, and much of that wear isn’t visible from the ground.
As your roofing contractor, we’ll look over the whole roof before recommending anything. Depending on its condition, that could mean maintenance, a targeted repair, or a new asphalt shingle roof. Most roofing problems don’t call for a full replacement, and we’ll be upfront when yours doesn’t. Learn more about roof replacement.
More Exterior Services for South Beloit Homeowners
Siding Replacement
Cracked, warped, loose, or faded siding lets moisture reach the walls behind it and makes the home look tired. We replace damaged sections and install new siding, finishing the trim so the exterior looks complete.
Gutter Replacement
Leaking, sagging, overflowing, or loose gutters spill roof runoff onto your siding and near your foundation. We install seamless gutters that carry water away from the house.
Soffit/Fascia Replacement
Fascia supports the gutters and seals the roof edge, and vented soffit helps the attic breathe. Loose, damaged, or aging boards should be replaced to keep the roofline protected and finished.
Door Replacement
Drafty, sticking, or damaged doors are a daily frustration. We replace entry and patio doors, measuring carefully so each one fits square, seals well, and swings smoothly.

Frequently Asked Questions
Drafts, fog between the panes, sticking sashes, faulty locks, and soft or cracked frames are the most common signs. When several windows share these problems, replacement is usually the better long-term choice.
Yes. Many homeowners start with the windows causing the most trouble and replace the rest over time. We’ll help you prioritize.
We remove each old window, prepare the opening, and install, seal, and trim the new one. Then we clean up and test every window with you.
Insulated glass has a sealed gap between the panes. When the seal fails, moist air gets inside and fogs the glass from within, where it can’t be cleaned. Replacing the window or glass unit is the usual fix. Moisture on the room side of the glass is a different issue, usually caused by indoor humidity.
After a storm with strong wind or hail, when you notice missing shingles or a leak, or if your roof is getting older and hasn’t been checked recently.
Isolated damage, like a few missing shingles or loose flashing, can usually be repaired. Widespread wear, recurring leaks, or a soft roof deck point toward replacement.
Cracked, warped, or loose panels, uneven fading, and gaps at seams or corners are worth having checked.
Replace gutters when they leak in several places, sag, or overflow even when clean. Replace exterior doors when they’re drafty, stick, won’t latch, or are warped or damaged.
