How we handle new build mastic in Wallington
We work in new homes and on new-build sites across Wallington. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. Typical jobs include leaking shower tray seals in a new home and worktop and upstand sealant coming away, across show homes, windows & doors and plot handovers.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

New homes and floors in Wallington
The South East is one of the drier parts of the UK, 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 snags may need reporting through the developer or the managing agent.
As a London address, Wallington can be tricky for parking: let us know about parking bays, permits or a driveway.

What affects the quote in Wallington
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Whether the work is at height
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors as agreed.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. In a London area like Wallington, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

When to call us in Wallington
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
People generally contact us when they notice something like this:
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Internal frame sealant that has split
If you’ve bought a new home near Wallington station, the sealant around baths, showers and frames is worth checking in the first year or two.

- When the joint can take water or movement
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Raise failed sealant with the developer while you’re covered
- Don’t wait for the house to settle if water is getting through
- Don’t seal over failed sealant yourself
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Honest limits
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
