About our new build mastic in Chadlington
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. If you have leaking shower tray seals in a new home and plot mastic for developers ahead of handover, we can put it right.
Somewhere as small as Chadlington, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- The size of the job
- The number of rooms or windows
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Photos by email, if that is easy
- Any access issues, like height or stairs
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

What we’re called out for in Chadlington

The most common problems we see are:
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes

What your quote should include
- How long the guarantee is
- How much experience the applicator has
- Is the old sealant removed completely?

When something else is needed
To be straight with you, some problems need a different trade:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Chadlington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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. Your quote takes all of that into account.

Common questions in Chadlington
Can you help a landlord with a rental near Charlbury station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover Chadlington for new build mastic?
Yes. We work across London and the South East, and Chadlington is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Why has my new-build shower seal failed already?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
