New build mastic in Polton, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on bathrooms & en suites, kitchens and windows & doors, and people most often call us about smeared, uneven beads picked up at snagging and sealant applied over dusty or wet surfaces.
Work in a place like Polton is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What new build mastic looks like in Polton
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Around Polton, as everywhere, new build mastic is only as good as the preparation behind it.

When something else is needed
We will not take on work that will not last, so here’s what sealant can’t put right:
- Cracking that points to a structural problem
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Show homes
- Plot handovers
- Kitchens

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not seal over failed sealant yourself
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. Around Polton, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Related advice
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
When to call us in Polton
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open.
Any of these means the joints need attention:
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Eskbank station, the sealant around baths, showers and frames is worth checking in the first year or two.

Polton: your questions answered
Will you come out to Polton?
Yes. Polton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Polton in your area for new build mastic?
Yes. We work across all of Scotland, and Polton is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
