Joints and finishes in Bandonhill homes
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among 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 Waddon station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic for homes and businesses in Bandonhill
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. Common call-outs are for skirting joints opening in the first winter and internal frame sealant that has split, across kitchens, show homes and plot handovers.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Bandonhill as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- Windows & doors
- Kitchens
- Plot handovers
- Show homes
- Skirting & floors
- Bathrooms & en suites
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Landlords, agents and businesses in Bandonhill

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
What we’re called out for in Bandonhill
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People normally contact us after spotting one of these:
- Cracks appearing as a new home settles
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
As a London address, Bandonhill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

If the building has a concierge, managing agent or access rules, tell us when you book.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
How to look after the new joints
To keep the joints looking good and working properly:
- Keep photos and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
