New build mastic in Purley, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We are often asked to deal with cracked caulk along new skirting and gaps opening as the house dries out and settles, on show homes, kitchens and windows & doors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Purley and beyond.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Purley. It helps if you can point us to a visitor permit or a bay close to the door.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate bathrooms well, especially in the first year
- Avoid scourers and strong chemicals on sealant
- Act quickly if a seal starts to leak
- Put sealant faults on your snagging list early
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.

What else we do in Purley
Why act early in Purley
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Purley.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Why us?
- Neat joints and a tidy finish
- You choose the colour before work begins
- Homes, businesses and hotels
- Old sealant always removed completely

Joints and finishes in Purley homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Purley can be tricky for parking: let us know about parking bays, permits or a driveway.

Purley: your questions answered
Do you cover Purley for new build mastic?
Yes. Our work covers London and the South East, and Purley is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Is parking a problem for a job in Purley?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Are you insured?
Yes. Full insurance covers our work.
Can I send you my snagging list?
Yes. Send it with photos and we will quote for the sealant items. If something is not sealant, we’ll say so.
Is it normal for sealant to crack in a new home?
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 do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can I do it myself?
If you are set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, 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.
Common problems we fix in Purley
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Common reasons people contact us include:
- Leaking shower tray seals in a new home
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
If you’ve bought a new home near Purley station, the sealant around baths, showers and frames is worth checking in the first year or two.
