New build mastic in Tooting Bec, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on plot handovers, bathrooms & en suites and show homes, and common reasons people get in touch are cracks appearing as a new home settles and untidy sealant flagged on a snagging list.
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.
Your job is guaranteed for a year, as with all our work.

The price is agreed before any work begins. It’s based on:

What new build mastic looks like in Tooting Bec
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Tooting Bec is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
When to call us in Tooting Bec
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
The most common problems we see are:
- Plot mastic for developers ahead of handover
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
If you’ve bought a new home near Tooting station, the sealant around baths, showers and frames is worth checking in the first year or two.

Your questions about new build mastic in Tooting Bec
I let a flat near Tooting station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you do new build mastic in Tooting Bec?
Yes. Our work covers London and the South East, and Tooting Bec is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
