- Gaps between new skirting and floors
- Second-fix sealing on new plots
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
New build mastic in Longman, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have frame joints opening as the plaster dries and second-fix sealing on new plots, we can put it right, whatever the surface.
For a place like Longman, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Big or small, you get the same one-year guarantee.

Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, drop us a line at info@mrmastic.co.uk with pictures. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before we start.

Longman is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.

Your questions about new build mastic in Longman
Is Longman within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Inverness station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long does new build mastic take?
Typically it takes a few hours in a single home. Larger jobs naturally take longer.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Aftercare tips
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Signs you need new build mastic in Longman
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
Signs it’s time to call us include:
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
In and around Longman, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
