How we handle floor joint sealing in Cuidhir
The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk usually cracks where there’s movement, so we use a flexible sealant that moves with the floor. We work on commercial floors, thresholds and skirting boards, and common reasons people get in touch are threshold joints that have opened or worn and caulk that has cracked where the floor moves.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
Every job comes with our 12-month guarantee.

Floor joint sealing around Cuidhir
Floors around Na h-Eileanan Siar run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Around Cuidhir, as everywhere, floor joint sealing is only as good as the preparation behind it. For buildings such as Cuier Parish Church and Churchyard, floor and skirting joints in halls and kitchens wear like any others.
Cuidhir is in Na h-Eileanan Siar. Jobs in Cuidhir get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Cuidhir is one of 87 places in Na h-Eileanan Siar where we work.

What happens if it’s left?
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Around Cuidhir, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What the job involves on each surface
Concrete floor joints
Hard wheels break down the edges of open joints. A sealed joint protects the edges.
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
