How we handle new build mastic in Horton Heath
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on show homes, windows & doors and bathrooms & en suites, and people most often call us about messy sealant that spoils new finishes and gaps opening as the house dries out and settles.
In and around Horton Heath, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Our work is backed for twelve months, in Horton Heath and everywhere else we cover.

What affects the cost of new build mastic

- Whether there’s mould to deal with
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
What we need to know
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Roughly how big the job is
- Whether it’s a home or a business
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 email pictures if that’s easy.
Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Horton Heath questions
Do you cover Horton Heath for new build mastic?
Yes. Our work covers London and the South East, and Horton Heath is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Do you work for landlords with property near Hedge End station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we will do.
Why has my new-build shower seal failed already?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Horton Heath, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

When to call us in Horton Heath
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Keep an eye out for these signs:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- New-build shower sealant that has already split
For new homes near Hedge End station, it’s worth checking the sealant early, while snags are still fresh.
