New build mastic in Chatham, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on show homes, bathrooms & en suites and plot handovers, and people most often call us about cracks appearing as a new home settles and gaps behind new kitchen upstands.
A place the size of Chatham has new developments as well as older streets. Snags in sealant and floor joints often show in a new home’s first year or two.
You get a 12-month guarantee, the same in Chatham as everywhere else we work.
What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours in a single home in most cases. Jobs in a place the size of Chatham range from town-centre flats to offices and family homes. For each, it helps to know about access, parking and where the joints are.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Your questions about new build mastic in Chatham
Can you do new build mastic in Chatham?
Yes, Chatham is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Chatham station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Where are you based?
Mr Mastic is based in Crawley. We cover Chatham and the rest of Medway, along with the rest of our area.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long should I leave it?
It depends on the product. Before we leave, we’ll tell you the cure time.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
What we cannot put right
A few problems are outside what sealant work can do:
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

What we’re called out for in Chatham
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Worktop and upstand sealant coming away
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
Around Chatham, as everywhere, new build mastic is only as good as the preparation behind it.
