Looking after it afterwards
So the new joints stay in good condition:
- Get cracks along tile grout lines looked at early
- Look at floor joints each spring
- Don’t slide heavy items over sealed joints
- Keep caulk for dry, still joints only
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Floor joint sealing for homes and businesses in St Leonard's
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk usually cracks where there’s movement, so we use a flexible sealant that moves with the floor. We’re often asked to deal with dirt and water collecting in open floor joints and grout used at the floor edge instead of sealant, on skirting boards, commercial floors and concrete floor joints.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. In St Leonard's, we cover those floor joints as well as plot mastic for developers.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Common problems we fix in St Leonard's
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. You’ll see a crack running along the grout, showing where a movement joint was needed.
Look out for these signs:
- Cracked caulk along skirting in bathrooms and kitchens
- Floor edges that trap water and grime
- Gaps opening between the floor and skirting
- Cracked grout where a tiled floor needs a movement joint
If you let a flat or house near Edinburgh Waverley station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Questions to ask before booking
- Who turns up on the day
- How long to leave it before use
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job normally takes a few hours for most rooms, longer for large commercial floors, and we explain the cure time before we leave. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In St Leonard's, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height

Leave it or put it right?
Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. Scottish rain finds any gap around a frame or wall joint, and in a tall building in St Leonard's, damp can travel a long way before it shows.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

New homes and floors in St Leonard's
Across Edinburgh, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you look after a building such as St Trinnean's School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What the job involves on each surface

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
