Exterior Remodeling & Window Replacement in Oconomowoc, WI
Wilco Exteriors replaces and installs windows for Oconomowoc homeowners and provides residential roofing services, siding, exterior doors, gutters, and soffit and fascia.

We’ll inspect it for free, show you what we find, and give you a written estimate you can review on your own time.
Window Replacement in Oconomowoc, WI
Water on the sills every morning, a window that swells shut in summer, a lock that gave up years ago, and a room that’s always a few degrees off are all signs your windows have reached the end of their run.
Wilco provides window replacement for Oconomowoc homeowners with energy-efficient vinyl and fiberglass replacement windows. Our window installers measure every opening individually, set each window square so it operates smoothly, and seal the full perimeter against air and water before finishing the trim.
That careful installation is what makes new windows close up drafts, open easily, and keep rooms more comfortable. See our window replacement page for more on materials and glass.
Common Window Problems
These are the issues we see most often when homeowners call us about replacement windows:
Drafts Around the Frame A steady chill near the window, even with it closed and locked, points to a worn seal or loose fit.
Fog Between the Panes Cloudiness inside the glass means the seal has failed and moisture has worked its way in.
Windows That Stick Sashes that swell, drag, or jam partway make opening a window more trouble than it’s worth.
Difficult Locks Latches that need forcing, spin loosely, or miss the keeper no longer hold the window tight.
Deteriorating Frames Soft spots, peeling finish, or cracked vinyl mean the frame itself is breaking down.
Windows That Won’t Stay Open Once the balances wear out, the sash drops back down the moment you let go.
When problems like these pile up, repairs rarely hold for long. A replacement window starts fresh with a unit sized for the opening, secured in place, and sealed around its edges. That closes the gaps that let drafts in, so the space near the glass feels like part of the room again.
Energy-efficient glass adds another layer of comfort. Insulated panes slow the movement of heat through the window, keeping more warmth inside in winter and limiting heat gain in summer. Your heating and cooling system has less to overcome, though how much you notice depends on your home and your current windows.
New windows also make everyday life easier. They open with light pressure, stay put, and lock on the first try. From outside, clean frames and clear glass give the house a fresher look.
Replacement Window Options for Your Home
Every opening has a job to do. Some need to open wide for fresh air, some need to be easy to reach, and some are mainly for light and the view. We’ll look at each one with you and help you choose based on the room, your home’s style, and your budget.
Double-Hung Replacement Windows
Double-hungs let you open the top sash, the bottom sash, or both, which makes them flexible for bedrooms and living areas. The sashes tilt in so you can clean the outside glass from indoors.
Sliding Replacement Windows
Sliders glide sideways with an easy push, so there’s no lifting involved. They’re a smart fit over counters, in basements, and in openings wider than they are tall.
Picture Windows
A picture window is one fixed pane that brings in plenty of daylight and keeps the view clear. It’s often paired with operating windows on either side for airflow.
Custom-Fit Replacement Windows
Existing openings are often slightly out of square or a non-standard size. We measure each one and order windows to match, which is what allows every window to seal properly and look finished.
Vinyl or Fiberglass
Vinyl is budget-friendly and needs very little upkeep. Fiberglass costs more but is a rigid material that holds its shape as temperatures change. We’ll walk you through both so you can choose what fits 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’ll meet you at your home, hear which windows are giving you trouble, and ask how you use each room. Then we look at the windows in person. The visit and estimate are free, and you can take whatever time you need to decide.
Evaluating Your Existing Windows
We test each window’s operation and lock, check for fogged glass and failed seals, and inspect frames and sills for rot, cracks, or warping. We also look at the surrounding wall and trim for moisture and explain what we find in plain terms.
Choosing Your Replacement Windows
Once we know which windows need replacing, we’ll help you choose styles, materials, and glass for each opening. We take precise measurements and give you an itemized written quote, so you know what’s included before anything is ordered.
Preparing for Installation
When your windows are ready, we’ll schedule installation on a day that works for you. We’ll also let you know how to prepare, such as moving furniture away from the windows and taking down blinds or curtains, so the crew can start right away.
Replacement Window Installation
Our crew removes each old window, cleans and prepares the opening, and sets the new window plumb, level, and square. Every window is secured, sealed, and trimmed. If we uncover damaged framing, we’ll show you and discuss the repair before continuing.
Cleanup and Final Walkthrough
After installation, we clear out the old windows and clean the work areas inside and out. Then we walk through your home together, testing each window so you can see it opens, closes, and locks properly.
Your timeline depends on the number of windows, their sizes, and the condition of the openings. We’ll give you a realistic schedule during your estimate and let you know if anything changes.
Residential Roofing in Oconomowoc, WI
Wilco Exteriors is also a roofing contractor serving Oconomowoc homeowners. Our residential roofing services include roof inspections, storm-related evaluations, repairs, roof replacement, and new roof installation.
Homeowners usually call our roofers after noticing something specific, like shingles in the yard after a windy night, shingles that look curled or cracked, a stain spreading across a ceiling, or flashing pulling away from a chimney or vent. Others simply have an older roof and want to know where it stands.
Wisconsin weather wears on roofing a little at a time. Snow and ice sit on the roof and build along the eaves. Storms bring wind that loosens shingle edges and rain that tests every seam. Freeze-thaw cycles gradually loosen fasteners and break down sealants. Most of that wear can’t be judged accurately from the ground.
That’s why every project starts with a close look at the whole roof. From there, we recommend what your roof actually needs, whether that’s a targeted repair or a full replacement with a new asphalt shingle roof. A few damaged shingles rarely mean you need a new roof, and as your roofing company, we’ll tell you when a repair makes more sense.
Roof Inspections
A roof inspection shows you where your roof stands before you decide what to do. It’s worth scheduling if you’ve noticed missing or damaged shingles, a leak, loose flashing, or visible wear, or after a storm with strong wind or hail. It’s also useful if you have an older roof and want an honest read on how much life it has left.
We check the shingles across the entire roof, the flashing around chimneys and vents, and the valleys and roof edges, and we look for soft or deteriorating areas. If there’s a leak, we trace it to where water is actually getting in. Storm-related damage is documented. Then we explain what we found. Often that means a simple repair or no work at all.
Roof Replacement and Installation
Replacement makes sense when the roof’s overall condition calls for it. We look at the age of the materials, how far deterioration has spread, the extent of any damage, whether problems keep coming back, and the condition of the decking and underlayment. When those point the same way, a new roof is usually a better investment than another round of repairs.
When a roof replacement is the right call, 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 your roof installation begins, we’ll review the scope with you, help you choose shingles that suit your home, and explain what to expect. We’ll keep you updated throughout, then clean up and inspect the finished roof before calling the job done. Learn more about roof replacement.
Siding Installation & Replacement in Oconomowoc, WI
Siding protects your walls from rain, snow, and wind, and it shapes how your home looks from the street. Over time, panels can crack, warp, loosen, or fade unevenly. Once that happens, moisture can get behind damaged sections and the house starts to look worn.
Some homeowners call a siding contractor to replace a damaged section, like a wall that took the brunt of a storm or one side that’s weathering faster than the rest. Others want complete siding installation as a full exterior update, often paired with new windows or a new roof.
Wilco handles both kinds of projects. We inspect your current siding and the wall behind any damaged areas, then help you choose a style and color that suit your home. Our crew removes the old material, addresses any problems underneath, installs the new residential siding, and finishes the trim around windows, doors, and corners so the exterior looks clean and complete. Learn more about siding replacement.
Exterior Door Replacement
An exterior door gets used more than almost any other part of your home’s exterior, so wear shows up quickly. You might feel a draft around the edges, fight a door that sticks when the weather changes, or have to push and pull just to get it to latch. Weatherstripping flattens and cracks, and doors can warp, dent, or fade.
Replacing an exterior door is about more than the door itself. We measure the opening carefully, make sure the new unit sits square in its frame, and adjust it so it swings smoothly and latches cleanly. Then we seal it against the weather and finish the trim. That careful installation is what keeps a new entry door working the way it should, and it’s a natural project to pair with new windows or siding. Learn more about door replacement.

Gutter Replacement
Leaking seams, sagging sections, overflow, and gutters pulling away from the roofline send water down your siding instead of away from the house. We install seamless gutters that carry runoff from the roof edge to downspouts that move it away from your walls and foundation.
Soffit/Fascia Replacement
Fascia lines the roof edge, supports the gutters, and seals the roofline. Soffit covers the underside of the overhang, and vented soffit helps air flow into the attic. When these boards rot, loosen, or show damage, replacing them protects the roofline and gives the exterior a finished look.

Serving Oconomowoc, Wisconsin
Wilco Exteriors provides window replacement and installation, residential roofing, roof inspections, roof replacement, siding, exterior doors, gutters, and soffit and fascia for homeowners in Oconomowoc and the surrounding area.
Every season puts its own kind of stress on a home’s exterior. Winter tests window seals and door weatherstripping. Snow and ice build up on the roof and in the gutters, then melt and refreeze. Spring and summer storms drive wind and rain against siding and roof edges, and the sun slowly fades exterior materials. Most of that wear shows up gradually, first as a draft or a sticking door and later as leaks or visible damage.
When you notice something, we’ll come take a look, find the cause, and explain your options so you can decide what to handle now and what can wait.
Frequently Asked Questions
The biggest signs are drafts near the frame, fog between the panes, sashes that stick or won’t stay open, locks that don’t secure the window, and frames that are soft or cracked. One minor issue may be repairable. When several windows share more than one of these problems, replacement is usually the better long-term option.
Yes. Many homeowners start with the windows causing the most trouble and replace the rest over time. We’ll help you prioritize and make sure the new windows work well with the ones you’re keeping.
Our crew removes each old window, prepares the opening, and checks for hidden damage. The new window is set level and square, secured, sealed around the perimeter, and finished with trim. Before we leave, we clean up and test every window with you.
Consider an inspection if you notice missing or damaged shingles, a leak or ceiling stain, or loose flashing, or after a storm with strong wind or hail. It’s also a good idea if your roof is getting older and hasn’t been checked recently.
Replacement is worth considering when shingle damage is widespread, leaks keep returning after repairs, the decking feels soft, or the roofing materials have reached the end of their useful life. Isolated damage can often be repaired. An inspection will show which situation you’re in.
Look for a contractor who is licensed and insured, inspects the roof before quoting, explains findings clearly, and provides a detailed written estimate. Reviews from other homeowners and a verifiable business address are also good signs. Be cautious of anyone who pushes a full replacement without showing you why.
Watch for cracked, warped, or loose panels, uneven fading, gaps at seams or corners, and sections that look wavy. Moisture stains or soft spots on interior walls behind the siding can also point to a problem. We’ll inspect the siding and the wall behind it before recommending replacement.
It may be time if you feel drafts around the edges, the door sticks or drags, the latch or lock is hard to use, or the door is warped or damaged. Sometimes an adjustment or new weatherstripping fixes the problem. If the door or frame itself is failing, replacement is usually the better choice.
