FAQs for Limmo Peninsula
Is Limmo Peninsula in your area for new build mastic?
Yes. Our work covers London and the South East, and Limmo Peninsula is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Limmo Peninsula?
Parking in Limmo Peninsula, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
How do I get a quote for new build mastic in Limmo Peninsula?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We will confirm how long when we quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Limmo Peninsula and the rest of Greater London.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
New build mastic in Limmo Peninsula, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have untidy sealant flagged on a snagging list and plot mastic for developers ahead of handover, we can put it right.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- A tray or bath that is not properly supported, until it’s fixed
- Broken tiles or a split tray
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Why act early in Limmo Peninsula
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Advice
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wipe joints with warm soapy water
- Record problems with dated photos
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Common problems we fix in Limmo Peninsula
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
For new homes near Custom House station, it’s worth checking the sealant early, while snags are still fresh.
