Floor joint sealing in Newtown St Boswells, done properly
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, then clean, back and seal the joint. We work on concrete floor joints, commercial floors and skirting boards, and the jobs we see most are grout used at the floor edge instead of sealant and failed seals where bathroom floors meet baths and panels.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
There’s a 12-month guarantee on every job, large or small.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Use a well-wrung mop rather than flooding the floor
- Look at floor joints each spring
- Keep dirt out of the joints
- Act on grout cracks that run in a straight line
Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

I let a flat near Tweedbank station. Can you help?

Is Newtown St Boswells within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How much does floor joint sealing cost in Newtown St Boswells?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

How long will you be here?

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Damaged concrete that needs breaking out and repairing
- Floors that are uneven or need levelling
- Water getting under the tiles from elsewhere
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

What floor joint sealing looks like in Newtown St Boswells
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Floors around the Scottish Borders 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.
If you look after a building such as Newtown Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

When to call us in Newtown St Boswells
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.
Most people get in touch after spotting one of these:
- Perimeter joints in tiled floors filled with grout
- Cracked caulk along skirting in bathrooms and kitchens
- Failed seals where bathroom floors meet baths and panels
- Cracked grout where a tiled floor needs a movement joint
Rented homes near Tweedbank station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.
