Wilco Exteriors is a team of local roofers in Janesville, WI. We inspect, repair, and replace residential roofs, and we also handle windows, gutters, siding, and doors. Call us when a window lets in cold air or won’t lock, shingles go missing after a storm, gutters spill over, or siding starts to crack. We’ll schedule a free inspection, show you what’s going on, and give you a clear written estimate.
Window Replacement in Janesville, WI
For a lot of homeowners, the decision to replace windows comes down to one specific moment. The heat kicks on again and you realize the thermostat hasn’t budged. You go to open the bedroom window on the first warm spring day and it won’t move. You try to lock up before bed, and the latch on the patio-side window just turns in your hand.
Most of the time, those moments come after years of smaller signs: condensation fogging the space between panes, frames softening under peeling paint, sashes that won’t stay up without a stick propped underneath, and a chill that settles near the glass every evening.
Wilco provides window replacement in Janesville, WI for homes that have reached that point. We replace worn-out windows with energy-efficient vinyl and fiberglass units built to your measurements. Just as important, we focus on the installation itself. A new window only performs as well as the way it’s fitted, secured, and sealed into the opening, and that’s where our crew puts its attention.

What We Hear From Homeowners
Talk to enough homeowners about their windows and you start hearing the same stories. Here are the ones that come up most:
“The heat never seems to reach that room.” Cold air sneaking in around an old sash and fighting the furnace all winter.
“It’s like opening a stuck drawer.” Windows that grind, catch, or refuse to move without real effort.
“We keep a ruler in the sill to hold it up.” Balances that have worn out and can’t support the sash.
“The lock feels loose.” Hardware that turns but doesn’t draw the window closed.
“I can see water droplets between the glass.” A failed seal letting moisture into the insulating space.
“They just look tired.” Faded, cracked, or mismatched frames that date the whole house.
These problems often grow slowly until they become part of daily life. The good news is that replacement windows address them together instead of one at a time.
A properly fitted replacement window closes the gaps that let air through. Once the window is shimmed square, secured in the opening, and sealed around the perimeter, the cold spot near the glass goes away and rooms start to feel consistent from one side to the other.
Energy-efficient glass does the rest. Insulated panes reduce how much heat escapes in winter and how much the sun heats the room in summer. That means less strain on your heating and cooling system, though the difference depends on your home and the windows you’re replacing.
New windows also make everyday use easier. Sashes glide with one hand, stay open where you leave them, and lock firmly. And because windows are such a visible part of the exterior, new ones change how the whole house looks.
Replacement Window Options for Your Home
There’s no single right window for every opening. We’ll help you match each window to the room, the size and shape of the opening, how you want it to operate, and what you’d like to spend.
Double-Hung Replacement Windows
A practical fit for bedrooms and living spaces, especially on traditional homes. Open the bottom sash for a breeze, the top to let warm air out, or both. Tilt-in sashes make washing upper-floor windows much easier.
Sliding Replacement Windows
Sliders are a good choice where lifting a sash is awkward, like over a sink, behind a couch, or in a basement. They open sideways with little effort and work well in wide openings.
Picture Windows
When you want a room filled with daylight or an uninterrupted view, a picture window keeps it simple with one fixed pane. They’re often flanked by operating windows so the room still gets fresh air.
Custom-Fit Replacement Windows
Window openings shift as houses settle, and many aren’t standard sizes. We measure every opening and order your windows to match, which helps each one seal properly and look finished without oversized trim.
Vinyl or Fiberglass
Vinyl keeps costs in check and needs almost no upkeep. Fiberglass costs more and is a stiffer material that stays stable through temperature changes. We’ll explain how each fits your home, your plans, and your budget.
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’ll set a time to stop by and talk through what’s bothering you, from one problem window to a whole-house replacement. We’ll also ask how you use each room. Then we look at the windows in person. The consultation and estimate are free, and there’s no obligation to move forward.
Evaluating Your Existing Windows
Next, we open, close, and lock each window, check the glass for fogging and failed seals, and inspect the frames and sills for rot, cracking, or warping. We also look at the surrounding trim and wall for signs of water damage, then explain what we found as we go.
Choosing Your Replacement Windows
We’ll help you choose styles, materials, and glass for each opening based on the room and your priorities. After taking exact measurements, we put everything in a written quote so you can review every window and line item before anything is ordered.
Preparing for Installation
Once your windows are built and delivered, we’ll set an installation date that works for you. A few days before, we’ll let you know what to move, such as furniture near the windows and blinds or curtains, so the crew can get started without delays.
Replacement Window Installation
The crew removes one old window at a time, cleans and prepares the opening, and sets the new window square and level. Each one is secured, sealed, and trimmed. If we find rotted framing behind an old window, we’ll stop, show you, and discuss the fix before continuing.
Cleanup and Final Walkthrough
After installation, we clear out the old windows and debris and clean the work areas inside and outside your home. Then we walk through each room with you, testing every window to make sure it opens easily, closes fully, and locks the way it should.
The length of your project will depend on how many windows you’re replacing, their sizes, and whether any openings need repairs. We’ll give you a realistic schedule before work begins and let you know right away if anything changes.
Residential Roofing in Janesville, WI
Wilco Exteriors is also a residential roofing company based right here in Janesville. For homeowners comparing roofers, we start every project the same way: we take a close look at your roof and explain its condition before recommending any work.
People usually call us because something has changed. Maybe a windstorm left shingles scattered across the lawn. Maybe a stain showed up on the bedroom ceiling after a heavy rain, or the flashing around the chimney started pulling loose. Sometimes it’s more subtle, like shingles that look curled or cracked, granules collecting at the bottom of the downspouts, or simply knowing the roof has been up there a long time without anyone checking it.
Wisconsin weather wears on a roof gradually. Snow can stay in place for weeks, and ice builds along the eaves. Spring and summer storms bring wind that lifts shingle edges and rain that finds weak spots in flashing and valleys. Freeze-thaw cycles and seasonal temperature swings slowly loosen fasteners and break down sealants.
Most of that wear isn’t visible from the driveway, so our residential roofing services start with an inspection. We check shingles, flashing, vents, valleys, and roof edges, trace leaks back to their source, and document any storm damage we find. Then we recommend the work that fits your roof’s actual condition. That might be a targeted repair, an evaluation after a storm, or a full roof replacement with a new asphalt shingle roofing system.
Among roofing companies serving Janesville homeowners, we aim to be the one that gives you a straight answer, even when that answer is that your roof only needs a small repair.
Seamless Gutters in Janesville, WI
Gutters are easy to forget until they stop working. Then you notice water pouring over the edge in a heavy rain, a corner dripping onto the front steps, or a long run of gutter sagging between hangers. Other common signs include leaking seams, sections pulling away from the roofline, dents or cracks, and downspouts that dump water right beside the house.
A gutter system’s job is simple: collect rainwater and snowmelt as it comes off the roof and move it away from your roof edges, siding, exterior walls, and the ground around your foundation. When it can’t do that, water ends up running down the side of the house instead.
Wilco installs seamless gutters for Janesville homeowners. Unlike sectional gutters pieced together every few feet, seamless gutters are formed in continuous lengths for each run, so the only joints are at the corners and downspouts. Fewer seams mean fewer places for leaks to start.
Our gutter installation includes sizing the system for your roof, setting the proper pitch so water flows to the downspouts, securing the gutters to the fascia, and positioning downspouts to carry runoff away from the house. If your current gutters only need a minor repair, we’ll tell you. If several runs are leaking, sagging, or worn out, gutter replacement is usually the more dependable fix. Learn more on our gutter replacement page.
Roof Replacement in Janesville
Replacement makes sense when a roof’s overall condition calls for it, not because of one bad spot. We look at how old the roofing materials are, how widespread the wear or damage is, whether leaks keep coming back after repairs, how much storm damage there is, and the condition of the roof deck underneath. If most of those factors point in the same direction, a new roof is usually a better use of your money than another round of repairs.
When roof replacement is the right choice, our crew handles each step:
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
Before work starts, we’ll go over the scope, help you choose shingles, and explain what to expect. For more details on materials and the process, see our roof replacement page.
More Exterior Services for Janesville Homeowners
Soffit/Fascia Replacement
Fascia runs along the roof edge, supports your gutters, and seals the roofline from weather and animals. Soffit covers the underside of the overhang, and vented soffit helps air move into the attic. When these boards start to peel, soften, or sag, replacing them protects the roofline and gives your exterior a finished look.
Door Replacement
A door that lets in drafts, sticks in its frame, or doesn’t latch cleanly is something you deal with every day. We replace entry and patio doors with options that seal tightly and swing smoothly. New doors also pair naturally with replacement windows and siding.
Siding Replacement
Siding that’s cracked, warped, loose, or faded doesn’t protect the walls behind it as well as it should, and it can make a well-kept house look older than it is. We handle siding replacement for damaged walls and complete siding installation for homeowners ready to update their exterior, from removing the old material to finishing the trim.

Frequently Asked Questions
Common signs include drafts near the frame, condensation between the panes, sashes that stick or won’t stay open, locks that no longer hold, and frames that are soft, rotted, or cracked. If only one window has one minor issue, a repair may be enough. When several windows show multiple problems, replacement is usually the better long-term choice.
Each old window is removed, and the opening is cleaned and checked for damage. Any rot or framing issues are addressed first. Then the new window is set level and square, secured in the opening, and sealed around the edges to keep out air and water. Interior and exterior trim finish the installation. Careful installation matters as much as the window itself because it determines how well the window seals and operates.
Yes. Many homeowners start with the windows causing the most discomfort or the ones in the worst condition, then replace the rest over time. We’ll help you prioritize and make sure new windows are a good match for the ones you’re keeping.
Replacement is worth considering when shingle damage is widespread, leaks return after repairs, the roof deck feels soft or uneven, or the roofing materials have reached the end of their useful life. Damage limited to one area can often be repaired. An inspection will show which situation applies to your roof.
Look for a roofer who is licensed and insured, inspects the roof before quoting, explains the findings clearly, and gives you a detailed written estimate. It’s also helpful to choose a company with a local address you can verify and reviews from homeowners in your area. Be cautious of anyone who pushes for a full replacement without showing you why it’s needed.
Seamless gutters are formed in continuous lengths for each run, so there are no joints along the straight sections. Fewer seams mean fewer places where leaks can develop. They also have a cleaner appearance along the roofline. Like any gutter system, they need proper sizing, pitch, and downspout placement to direct water away from the house.
Yes. Because we handle windows, roofing, gutters, siding, soffit and fascia, and doors, we can plan related work together. Common combinations include new gutters and fascia with a roof replacement, or replacement windows and siding as one project. We’ll help you decide what to do now and what can wait.
