New build mastic for homes and businesses in Smeaton
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on windows & doors, show homes and kitchens, and common reasons people get in touch are joints pulling apart as timber shrinks and new-build shower sealant that has already split.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A 12-month guarantee comes as standard.

What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Access and height
- The product the joint needs
- Working hours on commercial sites
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- If someone has resealed it before
- Where the property is
- How we’d reach the joints
- What’s wrong with the joints now
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Smeaton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Mention any tricky access

Advice
Signs you need new build mastic in Smeaton
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people usually mention when they call include:
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
In and around Smeaton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether you can choose the colour
- Which sealant they’ll use, and why
- When the joint can take water or movement
- How hidden problems are handled
Smeaton questions
Is Smeaton within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near East Linton station?
Yes. We work for letting agents and landlords as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Are you insured?
Yes, we are fully insured for every job we do.
Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule. Get in touch with the number of plots and the scope for a clear quote.

What else we do in Smeaton
Why act early in Smeaton
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. In a place like Smeaton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How to look after the new joints
So the new joints stay in good condition:
- Look at the sealant regularly in the first couple of years
- Clean sealant with mild detergent, not abrasives
- Keep water off fresh sealant until it has cured
- Record problems with dated pictures
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
What new build mastic looks like in Smeaton
Smeaton is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near East Linton station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Kitchens
