Plot mastic for developers and snagging failed sealant in new homes for Postling, backed by a 12-month guarantee. Ask us for a quote.
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
Looking after it afterwards
To keep the joints looking good and working properly:
- Act quickly if a seal starts to leak
- Avoid running a DIY bead over the old one
- Use the extractor fan every time you shower
- Watch for new gaps as the house dries out
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
New build mastic in Postling
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include kitchen sealant that has pulled off the wall and messy sealant that spoils new finishes, across skirting & floors, windows & doors and show homes.
For a small place like Postling, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Your job is guaranteed for a year, as with all our work.

Landlord and commercial work in Postling
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. In a small place like Postling, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- 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.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Mention if the joints have been sealed before

Advice
Why it’s worth doing now in Postling
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Postling, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
New homes and floors in Postling
Postling is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Sandling station, the sealant around baths, showers and frames is worth checking in the first year or two.
