New build mastic in Sandgate, 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. If you’re dealing with beads laid onto grit and dust from the build and smeared, uneven beads picked up at snagging, we can put it right, whatever the surface.
Around Sandgate, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Common problems we fix in Sandgate
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
Common reasons people contact us include:
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
In and around Sandgate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How do I get a quote for new build mastic in Sandgate?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Possibly a little. It fades as the sealant cures.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. In a small place like Sandgate, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Tell us about any water getting in
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Advice
Aftercare tips
Looking after new joints is easy:
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
Different surfaces, different methods
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing.
Why act early in Sandgate
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. Older cottages and farmhouses around Sandgate can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Sandgate is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. 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 Folkestone West station, it’s worth checking the sealant early, while snags are still fresh.
