Caulking & Sealing Vancouver
Windows, doors, trim gaps, baseboards, tubs and exterior seams sealed against Vancouver rain and drafts. The cheapest fix that prevents the most expensive damage. 5-year warranty.
In Vancouver, Caulking Is Water Defense
Caulking is the least glamorous job on a house and the one that quietly saves you the most money. A $300 reseal of your window perimeters can prevent a $15,000 wall-rot repair. In a city that gets 1,200mm of rain, that is not an exaggeration.
Every gap is a path for water. Failed caulk around windows lets rain into the wall cavity. Cracked seals at trim and siding joints feed rot and mould. Gaps at baseboards and door frames leak heat and let drafts in all winter.
We remove the old failed caulk first, which is the step most people skip. Tooling fresh sealant over cracked, mouldy old caulk just hides the problem for a season. Clean the joint, prime if needed, then lay a proper bead.
Window and door perimeters, siding and trim seams, baseboards and casing, tubs, showers and backsplashes, expansion joints and exterior penetrations all get the right sealant for the job, painted to match where it should be.
The Caulking Steps That Actually Hold
Six steps that separate a seal that lasts a decade from a bead that cracks by spring.
-
Cut out the old caulk.Failed and mouldy caulk is removed, not covered. New sealant only bonds to a clean joint. This is the step that makes the difference and the one DIY jobs skip.
-
Clean and dry the joint.We scrape, vacuum and wipe the gap so the sealant grips bare surface. Damp or dusty joints cause the bead to release within months.
-
Treat mould where present.Bathroom and exterior joints often hide mould. We treat it before sealing so it does not keep growing under the fresh bead.
-
Backer rod on wide gaps.Gaps wider than a quarter inch get a foam backer rod first so the sealant forms the right hourglass shape and does not sag or fail.
-
Right sealant for the spot.Paintable acrylic-latex on trim, flexible polyurethane on exterior seams, mould-resistant silicone in wet areas. The sealant is matched to the joint.
-
Tool and paint to match.We tool the bead smooth and, where it should be painted, coat it to match the trim or siding so the repair disappears.

Why Vancouver Owners Choose Us for Caulking & Sealing
We Remove Old Caulk First
Fresh caulk only bonds to a clean joint. We cut out the failed bead instead of tooling over it, which is the difference between a seal that holds and one that cracks by spring.
Right Sealant for Each Joint
Paintable acrylic on trim, polyurethane outside, mould-resistant silicone in wet areas. We match the product to the spot instead of one tube for everything.
Stops Rot Before It Starts
Sealing window and siding joints keeps water out of the wall cavity. It is the cheapest job we do and prevents the most expensive damage in this climate.
Painted to Disappear
Where caulk should be painted, we coat it to match the trim or siding so the repair is invisible, not a shiny line across your woodwork.
Part of Every Paint Job
We caulk as standard before exterior and interior repaints, but we also do caulking as a standalone service when that is all you need.
5-Year Written Warranty
Our sealing work is backed in writing. If a bead we installed fails or pulls away, we come back and make it right.

9 Vancouver Caulking & Sealing Tips Worth Knowing
- Caulking over old caulk never holds. Fresh sealant only bonds to a clean joint. Tooling a new bead over cracked, mouldy old caulk hides the gap for a season, then both fail together.
- Window perimeters are the first thing to seal. In Vancouver, failed window caulk is the most common path for rain into the wall. Reseal perimeters before the wet season and you prevent the priciest repairs.
- Use silicone in wet areas, acrylic on trim. Bathrooms need mould-resistant silicone that sheds water. Trim and baseboards need paintable acrylic-latex. Mixing them up means peeling or unpaintable beads.
- Wide gaps need backer rod. Anything wider than a quarter inch needs a foam backer rod behind the sealant. Without it the bead sags, sinks and fails.
- Treat the mould, do not seal it in. Black caulk in a shower is mould. Sealing over it just lets it keep growing. We treat the surface first so the fresh bead stays clean.
- Caulk before you paint, not after. Fresh caulk under fresh paint lasts far longer than a naked bead. Painting first and caulking later leaves the seal exposed to weather right away.
- Exterior sealing is a dry-day job. Polyurethane and acrylic need a dry surface to bond and dry time to skin over. We book exterior caulking for a dry stretch, not a rainy week.
- Drafts usually mean failed seals. Cold rooms and high heating bills often trace to gaps at windows, doors and baseboards. Sealing them is one of the cheapest comfort upgrades there is.
- Check seals every couple of years. Caulk is consumable. A quick reseal of the joints that have opened up, done every few years, prevents the slow water damage that adds up behind the wall.
Frequently Asked Questions
Why does caulking matter so much in Vancouver? +
Because of the rain. Vancouver gets well over 1,200mm a year, and every failed joint is a path for water into the wall. A small reseal of your window and siding perimeters is the cheapest job we do, and it prevents the most expensive damage, rot and mould inside the wall cavity, which can run into the thousands to repair.
Do you remove the old caulk first? +
Yes, always. Fresh sealant only bonds to a clean joint, so we cut out the failed, cracked or mouldy caulk, clean and dry the gap, then lay a new bead. Tooling new caulk over old is the most common DIY mistake. It hides the gap for a season, then the whole thing lets go together.
What kind of caulk do you use? +
Whatever the joint needs. Paintable acrylic-latex on interior trim and baseboards, flexible polyurethane on exterior siding and trim seams that move with the house, and mould-resistant silicone in tubs, showers and backsplashes. Using the right sealant for each spot is what makes it last instead of peeling or going mouldy.
Can you fix the black mould around my tub? +
Yes. That black line is mould growing in and under the old caulk. We remove the failed caulk completely, treat the mould so it does not keep spreading, dry the joint, then reseal with a mould-resistant silicone. Sealing over mouldy caulk, which is the usual quick fix, just traps it and it comes back fast.
Will sealing my windows help with drafts and heating? +
Yes. Gaps around windows, doors and baseboards leak heat all winter and let cold drafts in. Sealing them is one of the cheapest comfort and efficiency upgrades available. Many Vancouver homeowners notice warmer rooms and lower heating bills after a perimeter reseal, on top of the water protection.
Do you caulk as part of a paint job or on its own? +
Both. Caulking is standard prep before we do any interior or exterior repaint, because fresh caulk under fresh paint lasts far longer. But we also do caulking and sealing as a standalone service when that is all a home needs, which is common before the wet season.
When is the best time for exterior caulking? +
April through October. Exterior sealants need a dry surface to bond and a dry window to skin over and cure. Vancouver’s wet season does not reliably give that, so we book exterior caulking and weatherproofing for dry stretches, ideally before the heavy fall and winter rain arrives.
Is the caulking guaranteed? +
Yes. Our 5-year written workmanship warranty covers the beads we install. If a seal we applied cracks, pulls away or fails within that window, we come back and redo it. Caulk is a consumable that all homes need refreshed over time, but our work is guaranteed to hold its term.
