New Build Mastic in South Stour
Our applicators work in South Stour on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. In a small place like South Stour, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Advice
New build mastic in South Stour, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. Typical jobs include gaps between new skirting and floors and beads laid onto grit and dust from the build, across skirting & floors, bathrooms & en suites and windows & doors.
For a small place like South Stour, the journey and access are planned in advance, and the work itself is the same as on any site.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around South Stour can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

When to call us in South Stour
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.
Any of these means the joints need attention:
- Cracks appearing as a new home settles
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
In and around South Stour, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Who does the work, and how experienced they are

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Look at the sealant regularly in the first couple of years
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

Is South Stour within the area you cover?

Do you do commercial work?

Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
