Window Replacement in Waukesha, WI
Most homeowners start thinking about new windows after one too many small frustrations. A sash that won’t budge on the first warm day of spring. Fog between the panes that never clears. A window you have to prop open with a book, a frame that’s cracking under the paint, and a room that’s always a little cooler than the rest.
Wilco provides window replacement for Waukesha homeowners with energy-efficient vinyl and fiberglass replacement windows. Each opening is measured individually, so the new window fits its space instead of a close-enough standard size. During window installation, we set every unit square, seal the full perimeter against air and water, and finish the trim inside and out.
That attention to fit and sealing is what turns replacement windows into a real improvement. You get fewer drafts, smoother operation, and rooms that feel more comfortable. See our window replacement page for more on materials and glass options.
What We Hear From Homeowners
These are the issues we see most often when homeowners call us about replacement windows:
Drafts Around the Frame You feel moving air near the window even when it’s closed and locked.
Fog Between the Panes A haze inside the glass means the seal has failed.
Windows That Stick The sash drags, binds, or stops partway when you try to open it.
Difficult Locks The latch has to be forced or turns without pulling the window tight.
Deteriorating Frames Soft wood, peeling paint, or cracked vinyl show the frame is wearing out.
Windows That Won’t Stay Open The balances are worn, so the sash drops as soon as you let go.
When a window is properly sized, installed, and sealed, these problems go away together. Drafts stop, and the space near the glass stays comfortable. Energy-efficient glass helps rooms hold a steadier temperature, though how much you notice depends on your home and current windows. New sashes open easily, stay where you put them, and lock securely, and fresh frames give the exterior an updated look.
Replacement Window Options for Your Home
Waukesha 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
Both sashes move, so you can open the top, bottom, or both for airflow. They work in nearly any room, and the sashes tilt in for easy cleaning from inside.
Sliding Replacement Windows
Sliders open sideways with a light push, so there’s no lifting. They’re a smart pick over counters, in basements, and in openings that are wider than they are tall.
Picture Windows
One fixed pane that maximizes daylight and keeps the view clear. They’re often paired with operating windows on either side for ventilation.
Custom-Fit Replacement Windows
Window openings in existing homes are rarely perfectly square or standard-sized. We measure each one and order windows to fit, so they seal tightly and look finished.
Vinyl or Fiberglass
Vinyl is cost-effective and needs very little maintenance. Fiberglass costs more but holds its shape well through temperature swings. We’ll help you compare them for your home.
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 visit your home, hear what’s been bothering you, and look at the windows. The estimate is free, with no obligation.
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 pick styles, materials, and glass, measure every opening, and provide a written quote.
Preparing for Installation
When your windows arrive, we schedule your install and let you know what to move beforehand.
Replacement Window Installation
Our crew removes each old window, preps the opening, and installs, seals, and trims the new one. Any hidden damage gets shown to you first.
Cleanup and Final Walkthrough
We haul away the old windows, clean up, and test each new window with you before we leave.
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 Waukesha, WI
Wilco Exteriors is also a roofing contractor serving Waukesha homeowners, offering everything from storm-damage checks to complete new roofs.
Most people call our roofers after spotting shingles on the lawn, a water stain on the ceiling, or flashing pulling away from a chimney. Wisconsin’s snow, ice, storms, and freeze-thaw cycles wear on a roof gradually, and much of that damage can’t be seen from the ground.
That’s why our residential roofing work starts with a close look at the whole roof. Many problems can be handled with a targeted repair. When damage is widespread, a new asphalt shingle roof may make more sense. Either way, you’ll get a clear explanation and a straightforward price from a roofing company that won’t push work you don’t need.
Roof Replacement, Inspections & Installation
The right next step depends on your roof’s current condition. During an inspection, we check the shingles and flashing, look for visible deterioration, signs of leaks, storm-related changes, and recurring problem areas, and assess the overall health of the roofing system.
Roof replacement makes sense when deterioration is widespread, damage affects a large part of the roof, or the same problems keep returning after repairs. A few damaged shingles usually don’t call for a new roof, and we’ll tell you when a repair will do.
When replacement is the right choice, our roof installation process includes:
Removing the existing roofing materials
Inspecting the roof deck and underlying structure
Installing waterproofing and underlayment
Installing your new asphalt shingle roof
Cleaning up your property thoroughly when the job is done
Siding Installation & Replacement
Siding keeps rain, snow, and wind away from your walls and gives your home its finished look. When panels crack, warp, come loose, or fade, moisture can get behind them and the house starts to look tired.
Wilco is a siding contractor that handles both siding replacement for damaged areas and complete siding installation. We inspect your current siding and the wall behind any problem spots, help you choose a style and color, and handle everything from removing the old material to finishing the trim around windows, doors, and corners.
More Exterior Services for Waukesha Homeowners
Soffit/Fascia Replacement
Fascia supports your gutters and protects the roof edge, while vented soffit helps the attic breathe. Loose, damaged, or deteriorating boards should be replaced to keep the roofline protected and looking finished.
Door Replacement
Your entry door gets used every day, so drafts, sticking, and a latch that won’t catch are hard to ignore. Weatherstripping wears out, and doors can warp, dent, or fade. We handle door replacement and installation for entry and patio doors, measuring the opening carefully and adjusting each door so it sits square, seals tightly, and swings smoothly. New doors also pair well with replacement windows for a consistent exterior.
Gutter Replacement
Leaking, sagging, overflowing, or loose gutters let water run down your siding instead of away from the house. We handle seamless gutter installation, directing runoff away from your roof edges, walls, and foundation.

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 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.
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.
Look for a licensed and insured contractor who inspects before quoting, explains findings clearly, and provides a detailed written estimate. Local reviews and a verifiable address are good signs.
Cracked, warped, or loose panels, uneven fading, and gaps at seams or corners. We’ll check the wall behind damaged areas before recommending replacement.
When it’s drafty, sticks or drags, won’t latch properly, or is warped or damaged. New weatherstripping sometimes helps, but a failing door or frame is usually better replaced.
