New Build Mastic in Townhill Park
We cover Townhill Park for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Cracked sealant around new window and door frames
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors.
How we handle new build mastic in Townhill Park
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have second-fix sealing on new plots and joints pulling apart as timber shrinks, we can put it right.
Homes around Townhill Park range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
You get a one-year guarantee, the same in Townhill Park as everywhere else we work.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Joints and finishes in Townhill Park homes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Common questions in Townhill Park
Is Townhill Park in your area for new build mastic?
Yes, Townhill Park is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Swaythling station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
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 will quote.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
Landlords, agents and businesses in Townhill Park
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Leave it or put it right?
If you are 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. In a smaller place like Townhill Park, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
