New Build Mastic in The Hangers
Our applicators work in The Hangers on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Internal frame sealant that has split
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Older cottages and farmhouses around The Hangers can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Why The Hangers clients choose us
- Arbo and Everbuild products
- White, clear, grey or another colour, product permitting
- Anti-fungal sanitary silicone in wet areas
- Old sealant always removed completely

New build mastic for homes and businesses in The Hangers
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We work on skirting & floors, show homes and kitchens, and common reasons people get in touch are second-fix sealing on new plots and smeared, uneven beads picked up at snagging.
Around The Hangers, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, it’s backed by our 12-month guarantee.

When to call us in The Hangers
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Common reasons people contact us include:
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
In and around The Hangers, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- What happens if the job turns out different
- Is VAT in the price?
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. For a village or hamlet like The Hangers, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Clear the area around the work

Related advice
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
- Don’t seal over failed sealant yourself
- Act quickly if a seal starts to leak
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
What affects the cost of new build mastic
There’s no set price list. The quote depends on:
- How many areas need sealing
- The size of the job
- Whether the work is at height
- Working hours on commercial sites
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Where the property is
- What’s wrong with the joints now
- Roughly how big the job is

The Hangers: your questions answered
Will you come out to The Hangers?
Yes, The Hangers is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Botley station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
