New Build Mastic in Tatsfield
Problem with your new-build sealant joints in Tatsfield? We cut out the old, prepare the joints and apply the right sealant.

- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
How we handle new build mastic in Tatsfield
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you have sealant work across a run of new homes and gaps between new skirting and floors, we can put it right, on bathrooms & en suites, kitchens and show homes alike.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Whatever the size of the job, you get the same 12-month guarantee in Tatsfield and across Greater London.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
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.
Surface by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
When to call us in Tatsfield
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
These are the problems we are asked about most:
- Smeared, uneven beads picked up at snagging
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
For new homes near Oxted station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- What product goes in the joint
- How much experience the applicator has
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Mention any tricky access

How do I get a quote for new build mastic in Tatsfield?

Why act early in Tatsfield
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or send us an email with pictures and we will tell you. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear quote before work begins.
