About our new build mastic in Debden Green
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you’re dealing with cracked sealant around new window and door frames and untidy sealant flagged on a snagging list, we can help.
For a small place like Debden Green, the journey and access are planned in advance, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Debden Green
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Debden Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Can you do new build mastic in Debden Green?
Yes, Debden Green is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
