About our new build mastic in Woolmer
Across Woolmer, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Typical jobs include untidy sealant flagged on a snagging list and sealant that never bonded to the surface, on plot handovers, show homes and kitchens.
In a village or hamlet like Woolmer, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee, large or small.

The process
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours in a single home, including the tidy-up. For a village or hamlet like Woolmer, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant

What colour sealant will you use?

Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
New homes and floors in Woolmer
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Liss station, it’s worth checking the sealant early, while snags are still fresh. Around Woolmer, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.

What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Woolmer can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
