- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list

How we handle new build mastic in Tower Hill
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have cracks appearing as a new home settles and messy sealant that spoils new finishes, we can help.
In a village or hamlet like Tower Hill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same one-year guarantee.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home, and the area is left clean. In a small place like Tower Hill, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

New build mastic in Tower Hill: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Surface by surface

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
- Watch for new gaps as the house dries out
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Common questions in Tower Hill
Do you work for landlords with property near Christs Hospital station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Tower Hill in your area for new build mastic?
Yes. Our work covers London and the South East, and Tower Hill is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
