Aftercare tips
A little care helps the new joints last. Our advice:
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
- Don’t seal over failed sealant yourself
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
How we handle new build mastic in Plaistow
We work in new homes and on new-build sites across Plaistow. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on show homes, plot handovers and kitchens, and people most often call us about beads laid onto grit and dust from the build and untidy sealant flagged on a snagging list.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Plaistow and beyond.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Questions from Plaistow
Is parking a problem for a job in Plaistow?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is Plaistow in your area for new build mastic?
Yes. We work across London and the South East, and Plaistow is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
How long does the job take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.

What the job involves on each surface
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.
Work for landlords, hotels and businesses
For anyone letting property in or around Plaistow, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a job in Plaistow, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Joints and finishes in Plaistow homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Plaistow can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For new homes near Sundridge Park station, it’s worth checking the sealant early, while snags are still fresh.
Plaistow is about 1 mile north of Bromley, in Greater London. From the centre of Plaistow to the outskirts, we cover new build mastic for every kind of property. Our Greater London coverage runs to 764 places, Plaistow among them. You can also see our page for London, about 7 miles away.
All of BR1, BR2 and BR3 is within our area for new build mastic, from the main roads to the quietest streets. If you need new build mastic at a property on Saxon Road, Arcus Road and Croft Road or anywhere close by, our applicators can take on the job. Close by, we work in Downham (1 mile north), Sundridge (1 mile east), Grove Park (1 mile north-east), Bromley (1 mile south) and Chinbrook (1 mile north-east). Within a short drive, we also cover London (7 miles north-west), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (11 miles north-west), St Pancras (9 miles north-west) and Shoreditch (8 miles north-west).
What’s near Plaistow
We work in homes and buildings around Holy Trinity College Bromley, The Railway Tavern and Haberdashers' Aske's Knights Academy and the streets around them. For rail, the closest station is Sundridge Park station, about 0.6 miles south-east of the centre. A little further out are Greenwich Castle (4.1 miles north) and Prefab Museum (1.3 miles north-west). Not far away are Downham Woodland Walk and Summer Hill.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
