Advice
Why it’s worth doing now in Hawbush Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Hawbush Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Why us?
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
- We leave the area clean and tidy
- Sanitary silicone with an anti-fungal additive in wet areas
What new build mastic looks like in Hawbush Green
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.
Around Hawbush Green, as everywhere, new build mastic is only as good as the preparation behind it.

Signs you need new build mastic in Hawbush Green
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
These are the problems we are asked about most:
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
For new homes near Cressing station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Is VAT in the price?
- How the surfaces are prepared before sealing
- What the cure time is
- Is the old sealant removed completely?
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Don’t seal over failed sealant yourself
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Common questions in Hawbush Green
Is Hawbush Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Hawbush Green for new build mastic?
Yes, Hawbush Green is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Hawbush Green and the rest of Essex, along with the rest of our area.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What we cannot put right
It helps to know what we can’t do too:
- A tray or bath that isn’t properly supported, until it’s fixed
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Kitchens
- Plot handovers

What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
