New build mastic in Forty Green
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Typical jobs include beads laid onto grit and dust from the build and internal frame sealant that has split, across skirting & floors, show homes and plot handovers.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Why act early in Forty Green
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Forty Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

What we can’t put right
New sealant cannot fix everything, and we will tell you before we start. It won’t solve:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
Joints and surfaces we work on

When to call us in Forty Green
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Common reasons people contact us include:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
Around Forty Green, as everywhere, new build mastic is only as good as the preparation behind it.

- What the quote includes, VAT included or not
- Which sealant they’ll use, and why

Common questions in Forty Green
Can you do new build mastic in Forty Green?
Yes, Forty Green is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Will you come out to Forty Green?
Yes. Forty Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I go to my builder first?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Is it normal for sealant to crack in a new home?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
How do I get a quote for new build mastic in Forty Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
How long does new build mastic take?
A typical job takes anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
