Expert Siding Caulking & Sealing in Lawrence, KS

Siding caulking in Lawrence runs $350 to $1,400 for a whole-house exterior recaulk and $150 to $400 for a targeted fix, and it is among the highest return maintenance jobs on a home. Nearly all of the water that gets past siding gets past it at a joint, trim seam, corner, window edge or penetration. A tube of sealant applied correctly at those places prevents a long list of interior problems that are far more expensive to fix.

Two things separate a caulk job that lasts from one that fails in a year. The first is removal. Old caulk is cut out and scraped away before new goes in, because new sealant bonds to clean, dry substrate and not to the old bead. Caulking over failed caulk is why so many houses have layers of it. The second is joint geometry. A bead should bond to two surfaces and be free to stretch between them. Where a gap is wider than about a quarter inch, we pack it with backer rod first so the sealant bonds on two sides only. A bead bonded on three sides has nowhere to go when the joint moves, so it tears.

Just as important is what we leave uncaulked. The bottom edge of lap siding and the underside of horizontal joints stay open, because those gaps are how any water that gets behind the boards drains back out. Sealing them traps moisture in the wall.

Older Old West Lawrence houses give the hardest version of this job: wood siding that meets native limestone at the foundation or porch piers. The stone face is irregular, the two materials move at different rates, and a plain bead over that seam will not hold. Those joints get flexible sealant, backer rod for the wide gaps and, where it helps, a small flashing or trim detail so the sealant is not the only defense.

We handle trim, corner and penetration sealing, masonry joints, old-caulk removal, and color-matched or paintable finishes. Call 877-519-9702 for a free siding caulking estimate.

Our Process

How We Handle Siding Caulking & Sealing

Find Every Failed Joint

The exterior is walked joint by joint. Cracked, shrunken or pulled-away caulk is marked, along with the joints that should be left open to drain.

Remove the Old Sealant Completely

Old caulk is cut and scraped out, not caulked over, and the surfaces are cleaned, because new sealant only bonds to clean, dry material.

Size the Joint and Pack If Needed

Gaps wider than a quarter inch get backer rod so the caulk bonds on two sides only and can stretch. A bead bonded on three sides tears.

Tool and Match

A paintable or color-matched sealant is applied in a continuous bead, tooled to push it into the joint, and left to cure before any paint goes on.

How much does siding caulking cost in Lawrence?

A typical whole-house exterior recaulk runs $350 to $1,400 depending on size, height and how much old material has to come out. Small targeted fixes around a few penetrations or corners run $150 to $400.

Where should siding be caulked and where should it not be?

Caulk butt joints against trim, corners, and where siding meets windows, doors, vents, hose bibs and light fixtures. Never caulk the bottom edge of lap siding or the underside of a horizontal joint, because those gaps are how water that gets behind the siding drains back out.

Does vinyl siding need caulk?

Less than wood or fiber cement, but it does at trim, penetrations and utility openings. Vinyl expands and contracts a lot, so joints there use a flexible sealant, and the panels themselves should never be caulked tight to trim.

How long does exterior caulk last?

A good polyurethane or high-grade hybrid sealant typically lasts ten to fifteen years, while cheap acrylic latex can shrink and crack in three to five. The difference is a few dollars a tube against a repeat job every few years.

Are the joints where wood siding meets limestone on older Lawrence houses hard to seal?

They are the hardest joints on the house. Native limestone foundations and porch piers in Old West Lawrence have an irregular face that does not accept a straight bead, and the two materials move at different rates. Those joints need a flexible sealant, backer rod where the gap is wide, and often a small trim or flashing detail rather than caulk alone.
