New-build mastic & snagging in Easton, Isle of Wight
Professional new build mastic in and around Easton, with every bit of old sealant taken out first and a one-year guarantee.
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
New build mastic in Easton, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on windows & doors, skirting & floors and bathrooms & en suites, and the jobs we see most are cracks appearing as a new home settles and frame joints opening as the plaster dries.
Around Easton, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months.

Signs you need new build mastic in Easton
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The problems people normally mention when they call include:
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
Around Easton, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Who does the work, and how experienced they are
Aftercare tips
So the new joints stay in good condition:
- Look at the sealant regularly in the first couple of years
- Keep pictures and emails about snagging items
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are 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.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured.
How the visit works

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

New build mastic in Easton: local notes
Easton is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For jobs in and around Easton, choosing the right material for each joint is as important as a tidy finish.

FAQs for Easton

Can you do new build mastic in Easton?
Yes, Easton is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.

How long does the job take?
Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
When it isn’t the sealant
It helps to know what we can’t do:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
