Signs you need new build mastic in Betchworth
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
Look out for any of the following:
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
In and around Betchworth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. Somewhere as small as Betchworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Advice
Keeping the joints in good condition
Looking after new joints is easy:
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

New homes and floors in Betchworth
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Betchworth station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Betchworth
I let a flat near Betchworth station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Betchworth?
Yes. Betchworth is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room before we begin.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you guarantee your work?
Yes. All our work carries our one-year guarantee.
Where do you work from?
Mr Mastic is based in Crawley. We cover Betchworth and the rest of Surrey, along with the rest of our area.
