Hankham New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes in Hankham, with a one-year guarantee on every job. Ask us for a quote.
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, ring 0345 464 0079 or send us an email with pictures and we will tell you. Older cottages and farmhouses around Hankham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why Hankham customers choose us
- Any old sealant cut out fully, not covered over
- Anti-fungal silicone where joints get wet
- Fully insured
- Sealant colour chosen to suit

How we handle new build mastic in Hankham
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include worktop and upstand sealant coming away and smeared, uneven beads picked up at snagging, across plot handovers, kitchens and bathrooms & en suites.
In a village or hamlet like Hankham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

New build mastic around Hankham
Hankham is within about 3 miles 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Hankham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
When to call us in Hankham
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
It’s worth asking for a quote if you see:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
For new homes near Pevensey & Westham station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Who does the work, and how experienced they are
- What product goes in the joint
- Is the old sealant removed completely?
- How long to leave it before use
The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours in a single home. In a small place like Hankham, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
Getting a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Advice
Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common questions in Hankham
Is Hankham within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Pevensey & Westham station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
