New build mastic for homes and businesses in Ewell Minnis
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you’re dealing with joints pulling apart as timber shrinks and gaps between new skirting and floors, we can put it right, whatever the surface.
Older homes in small places like Ewell Minnis often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
How we quote for new build mastic
Your quote is based on your job. We take into account:
- When we can work, for business premises
- The old material and how stubborn it is
- Any mould that needs treating
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Whether it’s a home or a business
- What’s wrong with the joints now
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or drop us an email.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Ewell Minnis can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Raise failed sealant with the developer while you are covered
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
- Open a window or run the fan after bathing
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
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.
New build mastic around Ewell Minnis
Ewell Minnis is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Ewell Minnis, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Kearsney station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they won’t put it right, we will cut it out and reseal it.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
