New build mastic for homes and businesses in Paddington
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. We’re often asked to deal with worktop and upstand sealant coming away and untidy sealant flagged on a snagging list, on skirting & floors, plot handovers and show homes.
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 Paddington and beyond.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
Joints and finishes in Paddington homes
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
For new homes near London Paddington station, it’s worth checking the sealant early, while snags are still fresh.

Why act early in Paddington
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Paddington, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What you get with us
- Homes, businesses and hotels

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Resist patching a failed seal with a tube from the DIY shop
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
What we can’t put right
In fairness, some problems need a different trade:
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal

How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. 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.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Tell us about any water getting in
How to get a quote
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

Your questions about new build mastic in Paddington
Can you do new build mastic in Paddington?
Yes. Our work covers London and the South East, and Paddington is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Is parking a problem for a job in Paddington?
Parking in Paddington, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. Once that is done, or if they will not put it right, we can reseal it properly.
How long will you be here?
Most jobs take a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured for the work.
