Window Replacement & Exterior Remodeling in Harvard, IL
Wilco Exteriors helps Harvard homeowners replace and install windows, and we handle residential roofing too. Our team also works on siding, gutters, exterior doors, and soffit and fascia.

Window Replacement in Harvard, IL
It’s easy to put up with old windows for a few extra years. You learn which one needs an extra tug, which pane stays cloudy, and which room needs a sweater in January. Eventually, though, the drafts, sticking sashes, and cracked frames add up.
Wilco provides window replacement for Harvard homeowners with energy-efficient vinyl and fiberglass replacement windows. Our installers measure each opening individually, set every window square so it operates smoothly, and seal the full perimeter before finishing the trim inside and out.
Getting the fit and seal right is what makes new windows stop drafts, open easily, and keep rooms 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 Cool air moves past the window even with it shut and locked.
Fog Between the Panes Haze inside the glass means the seal has broken down.
Windows That Stick The sash binds in its track or takes real effort to move.
Difficult Locks The latch won’t line up or doesn’t hold the window tight.
Deteriorating Frames Soft spots, peeling finish, or cracked vinyl show the frame is failing.
Windows That Won’t Stay Open Worn balances let the sash slide back down.
A replacement window that’s sized for the opening and sealed properly resolves these issues together. Drafts stop, and the area near the glass stays comfortable. Sashes open with a light touch and lock securely, and energy-efficient glass helps rooms hold a more consistent temperature. New frames and clear glass also give the house a fresh, well-kept look.
Replacement Window Options for Your Home
Harvard 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 top sash, the bottom sash, or both. They’re a flexible choice for bedrooms and living areas, and the sashes tilt in so cleaning the outside glass is easy.
Sliding Replacement Windows
Sliders open sideways on a track, so there’s no lifting. They work well above counters, in basements, and in openings that are wider than they are tall.
Picture Windows
A single fixed pane that brings in as much daylight as possible and frames the view. Often paired with operating windows for airflow.
Custom-Fit Replacement Windows
Window openings are rarely a perfect standard size. We measure each one and order windows to match, so they seal tightly and look finished.
Vinyl or Fiberglass
Vinyl is budget-friendly and needs little upkeep. Fiberglass costs more but holds its shape well as temperatures change. We’ll help you compare both.
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, listen to your concerns, and look at your windows. The estimate costs nothing.
Evaluating Your Existing Windows
We check operation, seals, frames, and trim, then explain which windows need replacing and which can wait.
Choosing Your Replacement Windows
We help you choose styles, materials, and glass, measure every opening, and provide a written quote.
Preparing for Installation
When your windows arrive, we set an install date and let you know what to move.
Replacement Window Installation
Our crew removes each old window, prepares the opening, and installs, seals, and trims the new one. We’ll show you any hidden damage first.
Cleanup and Final Walkthrough
We clean up, haul away the old windows, and test each 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 Harvard, IL
Wilco Exteriors is also a roofing contractor for Harvard homeowners, providing roof inspections, repairs, roof replacement, and new roof installation.
Homeowners usually reach out after finding shingles in the yard, a ceiling stain after heavy rain, or flashing lifting around a chimney or vent. Northern Illinois snow, ice, thunderstorms, hail, and freeze-thaw cycles wear on a roof gradually, and much of that wear isn’t visible from the ground.
That’s why every project starts with a look at the roof’s current condition. From there, we’ll recommend maintenance, a targeted repair, or a new asphalt shingle roof based on what we find. Many problems don’t require a full replacement, and as your roofing company, we’ll tell you when they don’t. Learn more about roof replacement.
More Exterior Services for Harvard Homeowners
Siding Replacement
Cracked, warped, loose, or faded siding lets moisture reach your walls and makes the house 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 send water down your siding instead of away from the house. We install seamless gutters that move runoff away from your walls and foundation.
Soffit/Fascia Replacement
Fascia supports the gutters and protects 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 frustrating every day. 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 later. We’ll help you decide where to begin.
We remove each old window, prepare the opening, and install, seal, and trim the new one. Before we leave, we clean up and test every window with you.
Insulated windows have a sealed space between the panes. When that seal fails, humid air gets in and condenses on the inside of the glass, where it can’t be wiped away. Replacing the window or glass unit is the usual fix. Condensation on the room side of the glass is different and usually comes from 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.
Widespread shingle damage, recurring leaks, a soft roof deck, or materials at the end of their useful life point toward replacement. Isolated damage can usually be repaired.
Cracked, warped, or loose panels, uneven fading, and gaps at seams or corners are worth having checked.
When they leak in several spots, sag or pull away from the house, or overflow even when clean.
