Signs you need new build mastic in Firrhill
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Signs it’s time to call us include:
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
For new homes near Slateford station, it’s worth checking the sealant early, while snags are still fresh.

How we handle new build mastic in Firrhill
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have cracks appearing as a new home settles and sealant that never bonded to the surface, we can help, on kitchens, windows & doors and plot handovers alike.
In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. In Firrhill, a flexible sealant suits those joints better than filler.
All our work is covered by a 12-month guarantee, wherever you are in Edinburgh.

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.
FAQs for Firrhill
Is new build mastic in Firrhill guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Slateford station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Where do you work from?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.
Do you cover Firrhill?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Firrhill.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
New build mastic in Firrhill: local notes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. In a tenement flat in Firrhill, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Advice
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Raise failed sealant with the developer while you are covered
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
- Follow the cure time we give you
Watch the joints as the house settles. Small gaps can appear as the house dries.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
When something else is needed
New sealant cannot fix everything, and we will tell you before work begins. Sealant will not put right:
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
