Floor joint sealing for homes and businesses in Charlestown
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed using a product that suits the floor. We’re often asked to deal with worn sealant at door thresholds and rigid edge joints in tiled floors, across concrete floor joints, skirting boards and commercial floors.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What we’re called out for in Charlestown
A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands, and the sealant or grout breaks.
These are the problems we’re asked about most:
- Tiled floors with no room to move
- Rigid edge joints in tiled floors
- Open joints that fill with dirt
- Skirting that has pulled away from the floor
For buildings such as St Mary's Church, floor and skirting joints in halls and kitchens wear like any others.
What your quote should include
- How the surfaces are prepared before sealing
- How long to leave it before use
- Who does the work, and how experienced they are
- The length of the guarantee

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Act on grout cracks that run in a straight line
- Check the sealant is paintable before decorating
- Use furniture pads near skirting
- Check skirting joints after the heating season
Keep heavy furniture from dragging across the joints. Dragging can tear the bead before it has fully cured.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the floor safer.
What the job involves on each surface
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Tiled floors
Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant in a matching colour.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Floor joint sealing in Charlestown: local notes
Across Aberdeen, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For landlords with property near Portlethen station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a building such as Lochside Academy, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning or an afternoon for most homes, and the area is left clean. Somewhere like Charlestown may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can grout be replaced with sealant on a tiled floor?
Usually, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.
