New-build mastic & snagging in Hampton, Greater London
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Hampton and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
How we handle new build mastic in Hampton
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that’s what rushed new-build sealant generally lacks. We work on skirting & floors, plot handovers and windows & doors, and common reasons people get in touch are shower seals failing in the first year or two and sealant that never bonded to the surface.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Quotes for new build mastic in Hampton
We don’t publish a price list. The quote depends on:
- When we can work, for business premises
- Which sealant suits the joint
- The number and length of the joints
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Any access issues, like height or stairs
- The address or postcode of the job
- Whether it has been sealed before
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before we start.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In Hampton, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
How to get a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Advice
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Hampton.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we will quote. We will tell you if anything on it isn’t a sealant job.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
New build mastic in Hampton: local notes
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Hampton station, it’s worth checking the sealant early, while snags are still fresh. As a London address, Hampton can be tricky for parking: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
