About our new build mastic in Moulsecoomb
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. If you are dealing with smeared, uneven beads picked up at snagging and cracked caulk along new skirting, we can put it right, whatever the surface.
For a new home in or near Moulsecoomb, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Big or small, it’s backed by our one-year guarantee.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For a job in Moulsecoomb, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Related advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What we’re called out for in Moulsecoomb
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.
Keep an eye out for these signs:
- Internal frame sealant that has split
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Moulsecoomb station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- The number and length of the joints
- The product the joint needs
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- The rough size of the job
- The type of property
- How we’d reach the joints
- A few photos by email, if you can
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Homes in smaller places like Moulsecoomb can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

New build mastic in Moulsecoomb: local notes
Moulsecoomb is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.

Aftercare tips
After the cure time, these simple habits help:
- Use the extractor fan every time you shower
- Follow the cure time we give you
- Act quickly if a seal starts to leak
- Raise failed sealant with the developer while you’re covered
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
