New-build mastic & snagging in Hatton, Greater London
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in Hatton. Fully insured, ARBOMaster approved and guaranteed for a year.
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
New build mastic in Hatton
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on kitchens, bathrooms & en suites and skirting & floors, and people most often call us about joints pulling apart as timber shrinks and gaps between new skirting and floors.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
There’s a 12-month guarantee on every job.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Clean sealant with mild detergent, not abrasives
- Record problems with dated photos
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Your questions about new build mastic in Hatton
Is parking an issue for new build mastic in Hatton?
Parking in Hatton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you work for landlords with property near Heathrow Terminal 4 Rail station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
How long does new build mastic take?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Joints and finishes in Hatton homes
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Hatton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Surface 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.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.

How it works
There isn’t much for you to do on the day. 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 from start to finish. In Hatton, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any parking rules near the property
- Tell us about any water getting in
- Mention if the joints have been sealed before
How to get a quote
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.

What we are called out for in Hatton
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
If you’ve bought a new home near Heathrow Terminal 4 Rail station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- When the joint can take water or movement
- How much experience the applicator has
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Hatton, the repair is bigger than the sealant job would have been.
Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear quote for the lot.
