Do you need new build mastic in Epsom?
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
- Messy sealant that spoils new finishes
- Sealant work across a run of new homes
For new homes near Epsom station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- What guarantee comes with the work
- Whether you can choose the colour
- Whether they seal over old material or remove it
- Is VAT in the price?
New build mastic for homes and businesses in Epsom
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with second-fix sealing on new plots and untidy sealant flagged on a snagging list, we can put it right, on show homes, kitchens and skirting & floors alike.
Towns like Epsom have older streets and newer estates side by side. In a newer home, sealant and floor joints are normally among the first things to need attention.
You get a 12-month guarantee, the same in Epsom as everywhere else we work.

Advice

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. In a family home in Epsom, a failed seal around a bath or a frame lets water into places you cannot see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Keep water off fresh sealant until it has cured
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.

Why does sealant fail so quickly in new builds?
