New build mastic in Teston, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. 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. We are often asked to deal with worktop and upstand sealant coming away and frame joints opening as the plaster dries, on bathrooms & en suites, skirting & floors and windows & doors.
For a small place like Teston, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Teston questions
Do you cover smaller places like Teston?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Teston in your area for new build mastic?
Yes, Teston is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work through snagging lists?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.

Common problems we fix in Teston
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.
The problems people normally mention when they call include:
- Internal frame sealant that has split
- Gaps between new skirting and floors
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
In and around Teston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.

Leave it or put it right?

If you are unsure which you have, ring 0345 464 0079 or send us an email with photos and we will give you a straight answer. Around Teston, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Show homes
- Plot handovers

- Windows & doors
How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
