Caulking & Weatherproofing

Caulking & Weatherproofing I Handle Across the Tri-Cities

It's a small job on paper, but it's the difference between a house that stays dry and one that quietly doesn't. What I get called for most:

Exterior sealing of gaps, trim, and penetrations. Around pipes, vents, hose bibs, and wherever trim meets siding — the spots water finds first.

Window & door weatherstripping and draft sealing. I do weatherstripping doors and windows as standalone work or right alongside a repair.

Tub & shower re-caulk. Cut out the old, cracked, or mildewed bead and lay a clean one — part of most kitchen and bath repair visits.

Sealing around new fixtures. A fixture install isn't finished until it's sealed — I handle that after a new fixture goes in so water can't work its way behind the wall.

Sealing where materials meet. Siding gaps, trim-to-wall joints, and other transitions that open up over time and need re-sealing before they turn into a bigger repair.

Why Sealing Fails Fast in the Tri-Cities & High Country

Caulk doesn't get an easy life here. Freeze-thaw winters crack it and pull it loose from the joint a little more with every cold snap. Wind-driven rain — better than 45 inches a year in the valley — finds every unsealed gap around windows, doors, and trim and drives water straight in. And every gap that's not sealed is energy leaking out of the house right along with it. Up in the NC High Country, single-digit cold at elevation punishes a bad seal even harder, and a joint that was already marginal gives out that much faster.

Caulking Done Right vs. Done Wrong

Caulk is the finish, not a substitute for flashing or a real repair — it seals a sound joint, it doesn't fix a rotted one. Done right means the right sealant for the spot: 100% silicone in wet areas like the tub and shower, and a quality exterior polyurethane or elastomeric outside — not the cheap acrylic that shrinks and cracks within a season. It means a clean, dry joint and a bead that's actually tooled, not just squeezed out of the tube. Done wrong is caulk smeared over mildew, or packed into a gap that's still moving or still rotted underneath — that fails fast, and it's a big part of what I get called out to redo.

Mildewed, cracked caulk smeared over a gap — Caulk smeared over mildew or a moving gap fails within a season — the joint has to be clean, dry, and the right sealant.

How a Weatherproofing Job Goes With Me

1. You call and tell me what's going on — a drafty window, a cracked tub seam, gaps around a new fixture.

2. I take a look and check whether it's a straightforward re-seal or something underneath that needs fixing first, like a siding or exterior repair the caulk is currently hiding.

3. I cut out the old caulk, clean and dry the joint, and lay a fresh bead with the right sealant for that spot.

4. I tell you straight if what you're looking at is more than caulk can fix — I'd rather say that upfront than sell you a seal that won't hold. That's the same reason to have someone in your corner who isn't trying to sell you the biggest version of the job on anything larger.

Frequently asked questions

What caulk do you use, and where?+

100% silicone in wet areas like tubs and showers — it flexes and resists mildew. Outside, I use a quality polyurethane or elastomeric sealant built for exterior movement and weather, not the cheap acrylic that shrinks and cracks within a season.

Can you stop the drafts in my house?+

Often, yes. Old, cracked weatherstripping around doors and windows is one of the cheapest energy fixes there is, and I can usually knock out several openings in a visit.

Do you re-caulk tubs and showers?+

Yes — cutting out old, moldy, or cracked caulk and laying a clean silicone bead is regular work, often alongside other kitchen and bath repairs.

Why does my caulk keep cracking?+

Usually the wrong sealant for the spot, a joint that wasn't clean and dry when it was applied, or freeze-thaw working it loose year after year. Sometimes it's a sign of movement underneath that caulk alone can't fix.

Is caulk a fix for a leak?+

Honestly, no — caulk is the finish, not the fix. If there's an active leak or rot behind the joint, that needs to be repaired first. I'll tell you straight if that's what's actually going on before I reach for the caulk gun.
