Our Caulking &
Weatherproofing Services

A thin, failing bead of caulk is one of the fastest ways a Wisconsin home loses heat and takes on water. Apex Window Werks handles the full job — from scraping out brittle, discolored sealant to building a crisp new joint that seals out wind, rain, and snowmelt. Whether it is a single drafty bedroom window or the entire exterior envelope of a Cream City brick bungalow, we match the right sealant to each surface.

Caulk is the flexible seal that keeps water and air from sneaking around the edges of your windows and doors, and in Wisconsin’s climate it has a demanding job. The state’s wide temperature range forces materials to expand and contract constantly, and over time old caulk cracks, shrinks, and pulls away, opening gaps that let in drafts and moisture. Window and door caulking involves removing that failed material and applying fresh, weather-rated sealant to restore a tight barrier. For Wisconsin homeowners, well-maintained caulk lines are one of the simplest defenses against winter heat loss, water intrusion behind siding, and the drafts that make rooms uncomfortable. We seal the joints where frames meet the wall so your windows and doors keep performing efficiently season after season.

Exterior Window & Door Caulking

The outside face of your frames takes the full force of lake-effect weather. We remove weathered caulk, clean and dry the joint, and apply a weatherproof sealant that keeps rain and blowing snow out of the wall cavity, protecting your siding and sheathing from rot.

Interior Sealing & Draft-Proofing

Cold air sneaking in around the inside casing drives up your heating bills all winter. Our crew seals the gaps between the frame and the wall with a paintable, low-odor caulk, cutting drafts in older double-hungs and keeping your rooms comfortable room to room.

Old Caulk Removal & Re-Caulking

Peeling, cracked, or moldy sealant cannot be painted over and expected to hold. We cut and scrape out the old material down to a clean substrate, then re-caulk with a fresh, flexible bead so the seal actually bonds and lasts instead of lifting away again.

Silicone & Specialty Sealants

Not every joint wants the same product. We choose silicone for high-moisture, non-painted surfaces and acrylic-latex blends where a smooth, paintable finish matters. Matching the sealant to the material is what keeps a Wisconsin joint watertight through years of freeze and thaw.

Trim, Siding & Joint Sealing

Water finds every unsealed seam where trim meets siding or where two materials join. We tool neat, continuous beads along casings, brickmould, and transitions so moisture is shed away from the structure and your home looks finished and tight from the curb.

Signs Your Caulk
Has Failed

Caulk is the quiet first line of defense around every window and door, and in Wisconsin it works hard. When it lets go, the damage rarely stays small — drafts, stains, and rot follow close behind. Here is what tells our team a joint needs attention before the next deep freeze.

Cracked exterior caulk around a window frame

Cracked, Peeling Exterior Beads

The clearest warning sign is a bead you can see failing. When sealant cracks, splits, or pulls away from the frame, the seal is broken and water has a direct path into the wall. Wisconsin’s repeated freeze-thaw cycles are brutal on rigid, low-grade caulk, forcing it to shrink and lift season after season until the joint is wide open.

Drafts and Climbing Heating Bills

If you feel a cold ribbon of air near a window on a windy day, or your furnace runs harder than it should, unsealed joints are often the reason. Air leakage around frames is one of the largest hidden sources of energy loss in older Milwaukee-area homes. A fresh, continuous bead of caulk closes those gaps and keeps conditioned air where it belongs.

Water staining below a window from failed sealant

Water Intrusion and Wood Rot

Water that slips behind a failed joint does its worst where you cannot see it. Over time it soaks into sills, casings, and sheathing, feeding rot, peeling paint, and mildew. By the time stains appear indoors, the hidden damage is usually well underway. Resealing early is far cheaper than rebuilding a rotted frame or wall section.

Weatherproofing a joint against lake-effect weather

Freeze-Thaw and Lakefront Weather

Along Lake Michigan, temperatures swing above and below freezing again and again, and that movement tears at any joint sealed with the wrong product. We apply flexible, cold-rated sealants and provide lasting caulking solutions across Wisconsin that keep moving with your frames rather than cracking apart the first hard winter.

Apex Window Werks replaced the foggy glass on our kitchen window. They carefully removed the old glass pane and installed a new one, ensuring precise measurements and using silicone to secure it properly. From the first person I spoke to on the phone, to the couple of gentlemen who installed the glass, everyone was easy to talk to and they were all very professional. Highly recommended!

We had a broken seal in our thermopane window. The sales person came and measured, gave us a fair quote for a new thermopane window, and believe it or not, was installed the very next day! Very impressed with this company! Excellent service!

I got 3 quotes from other companies and Apex was the only company who said they could fix my window without replacing it. The guys came in and fixed the window in 20 minutes and I couldn’t be happier. Amazing service! I will be coming back for any window needs in the future. Thanks again for getting this taken care of so quickly!

FAQs about
Window & Door Caulking

How much does it cost to caulk windows and doors in Wisconsin?

It depends on the job. Pricing reflects how many openings you have, how much old caulk must be removed, the sealant required, and whether the work is interior, exterior, or both. A few drafty windows cost far less than resealing a whole home. Contact us and we will inspect the openings and give you a clear written estimate.

How long does exterior caulking last in a freeze-thaw climate?

A high-quality sealant applied to a properly prepped joint commonly lasts 10 to 20 years, but Wisconsin’s constant freeze-thaw movement shortens the life of cheap or poorly installed caulk dramatically. We recommend a quick annual look at exterior beads so small cracks are resealed before water works its way behind the frame.

Should I caulk the inside of my windows too?

Yes. Interior caulking seals the gap between the frame and the wall, stopping drafts and keeping conditioned air inside. It pairs with exterior caulking, which blocks rain and snowmelt from entering. Sealing both sides is the most effective way to cut energy loss and protect the structure around each opening.

What is the difference between silicone and latex caulk?

Silicone stays flexible, resists moisture, and excels on non-painted surfaces exposed to weather, but it cannot be painted. Acrylic-latex caulk is paintable, easy to tool, and ideal for interior trim and joints you want to color-match. We select the right product for each surface so the seal holds and the finish looks right.

Can old, cracked caulk simply be painted or sealed over?

No. Applying fresh caulk or paint over a failed bead traps the old problem underneath, and the new layer lifts away with it. The joint must be cut out, scraped clean, and dried first so the new sealant bonds to a sound surface. Proper removal is what separates a lasting seal from one that fails within months.

How do I know whether my windows need re-caulking or replacement?

If the glass and frames are sound but the joints are cracked, gapped, or leaking air and water, re-caulking restores the seal for a fraction of replacement cost. We inspect the frames, sills, and surrounding trim first and recommend resealing whenever the openings themselves are still in good structural shape.

How often should I re-caulk windows and doors in Wisconsin's climate?

There is no fixed schedule, but Wisconsin’s extreme temperature swings tend to break caulk down faster than milder climates. Inspect your seals each year and re-caulk when you see cracking, shrinking, gaps, or caulk pulling away from the frame. Catching and resealing those failures early prevents drafts and keeps water from working its way in behind the trim.
