New build mastic in Malden Rushett, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. If you’re dealing with new-build shower sealant that has already split and kitchen sealant that has pulled off the wall, we can help, whatever the surface.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Malden Rushett as anywhere.
Whatever the size of the job, you get the same 12-month guarantee.

When to call us in Malden Rushett
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
It’s worth asking for a quote if you see:
- Messy sealant that spoils new finishes
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
Malden Rushett is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

New build mastic around Malden Rushett
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. 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 Chessington South station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. In Malden Rushett, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Advice
How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- When we can work, for business premises
- Whether there’s mould to deal with
- Which sealant suits the joint
- How much there is to do
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
Asking for a quote
To help us quote quickly, please include:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Any access issues, like height or stairs
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Malden Rushett.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Why book with us
- Any old sealant cut out fully, not covered over
- You choose the colour before work begins
- Trusted Arbo and Everbuild sealants
- More than 20 years in sealant work

Malden Rushett: your questions answered
Is Malden Rushett in your area for new build mastic?
Yes. Our work covers London and the South East, and Malden Rushett is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is parking an issue for new build mastic in Malden Rushett?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours in a single home. We will tell you when we quote.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
When it is not the sealant
Before booking, it’s worth knowing the limits:
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

What else we do in Malden Rushett
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
