New build mastic in Great Milton
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We are often asked to deal with gaps between new skirting and floors and sealant applied over dusty or wet surfaces, across skirting & floors, windows & doors and show homes.
Work in a small place like Great Milton just needs the journey and access planning, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Advice
New homes and floors in Great Milton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Common questions in Great Milton
Is new build mastic in Great Milton guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Great Milton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
How long will you be here?
Typically it takes a few hours in a single home. Bigger jobs take longer.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a small place like Great Milton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Signs you need new build mastic in Great Milton
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
These are the problems we’re asked about most:
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
For jobs in and around Great Milton, choosing the right material for each joint is as important as a tidy finish.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Ventilate bathrooms well, especially in the first year
- Do not seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
- Act quickly if a seal starts to leak
Watch the joints as the house settles. Small gaps can appear as the house dries.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Landlords, agents and businesses in Great Milton
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
When it is not the sealant
It helps to know what we cannot do too:
- Cracked trays, tiles or worktops
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
