New Build Mastic in Surbiton Park
Problem with your new-build sealant joints in Surbiton Park? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
New build mastic in Surbiton Park, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces, across plot handovers, bathrooms & en suites and skirting & floors.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

New homes and floors in Surbiton Park
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
For new homes near Surbiton station, it’s worth checking the sealant early, while snags are still fresh.

What else we do in Surbiton Park
Signs you need new build mastic in Surbiton Park
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
These are the problems we are asked about most:
- Sealant work across a run of new homes
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
As a London address, Surbiton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- Who turns up on the day
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
Why act early in Surbiton Park
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

Your questions about new build mastic in Surbiton Park
Can parking be tricky for a visit in Surbiton Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is Surbiton Park in your area for new build mastic?
Yes. We work across London and the South East, and Surbiton Park is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
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. Larger jobs naturally take longer, and we will tell you how long to expect.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Greater London.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.

The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots.

- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
