About our new build mastic in Hurst Green
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. We’re often asked to deal with leaking shower tray seals in a new home and worktop and upstand sealant coming away, on windows & doors, show homes and skirting & floors.
In a village or hamlet like Hurst Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

The process
When we arrive, 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 a few hours in a single home. Somewhere like Hurst Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

Advice
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
What we seal
- Windows & doors
- Plot handovers
- Bathrooms & en suites
- Show homes
- Kitchens
- Skirting & floors
Do you need new build mastic in Hurst Green?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Signs it’s time to call us include:
- New-build shower sealant that has already split
- Gaps between new skirting and floors
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
For new homes near Etchingham station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Hurst Green
Can you do new build mastic in Hurst Green?
Yes. We work across London and the South East, and Hurst Green is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
I let a flat near Etchingham station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Where are you based?
Mr Mastic is based in Crawley. We cover Hurst Green and the rest of East Sussex.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Are you fully insured?
Yes, we’re fully insured.
How long will you be here?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
What happens if it’s left?
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Around Hurst Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- Any old sealant cut out fully, not covered over
- You choose the colour before work begins
- Every job guaranteed for a year
- Sealant colour chosen to suit

There’s no set price list. The quote depends on:
- Which sealant suits the joint

Photos by email are helpful but not essential. Please mention:

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
