CAULKING SERVICES
WE OFFER
Great spaces don’t just happen — they’re maintained with intention. Whether you're a homeowner or running a business, taking care of the small stuff now prevents the big, costly headaches later.
At DMZ Maintenance & Contracting Services, we believe in proactive care — because reliable repairs aren’t just about fixing what’s broken, they’re about protecting what matters.
Use this checklist to stay ahead, or share it with someone who needs a nudge. And when it’s time to call in a pro? We’re ready.
Seal out drafts, moisture, and costly repairs — one smart caulk line at a time.
⬜ Inspect interior window and door caulking for cracks, peeling, or gaps
⬜ Re-caulk any damaged exterior seals around windows and siding
⬜ Check bathroom caulk for mold, mildew, or shrinkage and reapply if needed
⬜ Clean and re-caulk kitchen sink edges and countertops if separation has occurred
⬜ Walk your home’s foundation and siding — seal any visible gaps to keep pests out
💡Did You Know? Old or cracked caulk can let in water — and even minor leaks can lead to mold, rot, or thousands in repairs if left unchecked.
⬜ Inspect caulking around tubs, showers, and sinks — moisture breaks it down over time
⬜ Re-seal outdoor caulking (doors, windows, vents) before peak humidity hits
⬜ Use paintable exterior-grade caulk to touch up any weathered trim or siding seams
⬜ Check expansion joints in patios or walkways and reapply flexible sealants
⬜ Seal around A/C units, hose bibs, and utility entry points
💡Did You Know? Caulking acts as insulation too — sealing small gaps around windows and doors can lower summer cooling costs by up to
10%
.
⬜ Seal exterior gaps around windows, doors, and attic vents before temperatures drop
⬜ Check basement windows and crawlspace vents for air leaks
⬜ Inspect interior caulking in kitchens and bathrooms as seasonal humidity shifts
⬜ Add fresh caulk to weatherstripping edges where drafts are common
⬜ Use silicone caulk for areas exposed to temperature extremes (like garages or basements)
💡Did You Know? Fall is the ideal time to re-caulk — materials cure best in moderate temps and will be fully set before winter weather hits.
❄️ Winter – Indoor Sealing & Comfort Checks
⬜ Check around indoor baseboards and trim — seal if you feel cold air
⬜ Inspect interior bathroom caulking for signs of shrinkage or mold from dry winter air
⬜ Re-caulk kitchen backsplashes or counters if cracking is visible
⬜ Use removable caulk (like draft seal) for temporary sealing on windows
⬜ Plan for spring exterior caulking needs during indoor project downtime
💡Did You Know? Silicone caulk can last 10+ years if applied correctly — regular inspections make sure you're still protected.
