About our floor joint sealing in Gilmerton
We seal floor joints in homes, offices and commercial buildings across Gilmerton. Each job starts with looking at the floor and the gap, because the right sealant depends on both. We work on tiled floors, concrete floor joints and thresholds, and the jobs we see most are worn sealant at door thresholds and grout used at the floor edge instead of sealant.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. In Gilmerton, a flexible sealant suits those joints better than filler.
Every job comes with our 12-month guarantee.

What the job involves on each surface
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it.
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product.
FAQs for Gilmerton
Is floor joint sealing in Gilmerton guaranteed?
All our work, in Gilmerton and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
I let a flat near Shawfair station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
How long does the job take?
As a guide, most jobs take a morning or an afternoon for most homes. Bigger jobs take longer, and we’ll say how long yours will take.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Where do you work from?
Mr Mastic is based in Crawley. We cover Gilmerton and the rest of Edinburgh.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
My floor grout keeps cracking in a line. Can you help?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant coloured to suit. If tiles are loose, that needs fixing first.
Signs you need floor joint sealing in Gilmerton
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges until the joint widens.
Look out for these signs:
- Worn sealant at door thresholds
- Floor edges that trap water and grime
- Open joints around bathroom floor edges
- Skirting that has pulled away from the floor
Managing a site like Gracemount High School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep heavy wheels off new concrete joints until cured
- Vacuum floor joints regularly to stop grit building up
- Get cracks along tile grout lines looked at early
- Check the sealant is paintable before decorating
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up.
Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.
When it is not the sealant
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Water getting under the tiles from elsewhere
- Structural movement or subsidence
- Tiles that have lifted or broken

Floor joint sealing around Gilmerton
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Floors around Edinburgh run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near Shawfair station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

A little further out are Cameron Toll Shopping Centre (2 miles north-west) and Craigmillar Castle (1.5 miles north). Open spaces near Gilmerton include The New Leaf Co-op and Duddingston Loch.
Why deal with it now?
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Private landlords in Gilmerton must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
