When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Plot handovers
- Skirting & floors
- Windows & doors
- Show homes
- Kitchens
- Bathrooms & en suites
Keeping the joints in good condition
Looking after new joints is easy:
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
- Don’t wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. Somewhere as small as Little Leighs, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
How to get a quote

Advice
Common problems we fix in Little Leighs
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
People generally contact us after spotting one of these:
- Sealant work across a run of new homes
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Cressing station, the sealant around baths, showers and frames is worth checking in the first year or two.

Little Leighs: your questions answered

Is Little Leighs in your area for new build mastic?

Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we will tell you how long to expect.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Why act early in Little Leighs
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Little Leighs can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
