How we handle new build mastic in Swinton
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have joints pulling apart as timber shrinks and worktop and upstand sealant coming away, we can help, on skirting & floors, bathrooms & en suites and kitchens alike.
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.
You are covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Photos by email, if that’s easy
- Whether it has been sealed before

How much does new build mastic cost in Swinton?
Every job is different, so each one gets its own quote. To get one, drop us a line at info@mrmastic.co.uk with a short description of the job.
How long does new build mastic take?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will tell you when we quote.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
What else we do in Swinton
Should I try it myself first?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated photos
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Around Swinton, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Keep children and pets away from the work area
- Mention any tricky access
- Try not to wet indoor joints just before the visit

Why act early in Swinton
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
