Questions from Pollards Hill
Can parking be tricky for a visit in Pollards Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Norbury station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What information do you need?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
How long will you be here?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
How we handle new build mastic in Pollards Hill
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have leaking shower tray seals in a new home and cracked sealant around new window and door frames, we can help, whatever the surface.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Pollards Hill as anywhere.
There’s a 12-month guarantee on every job.

Common problems we fix in Pollards Hill
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
As a London address, Pollards Hill can be tricky for parking: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Whether the sealant suits the joint
- Whether you can choose the colour
- How hidden problems are handled
- What the quote includes, VAT included or not
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
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, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Joints and finishes in Pollards Hill homes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
If you’ve bought a new home near Norbury station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you’re covered
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
