About our new build mastic in Chislet
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on show homes, bathrooms & en suites and plot handovers, and the jobs we see most are shower seals failing in the first year or two and joints pulling apart as timber shrinks.
Older homes in small places like Chislet often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, you get the same 12-month guarantee in Chislet and across Kent.

How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.

What else we do in Chislet
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Show homes
- Windows & doors
- Skirting & floors
- Plot handovers
- Kitchens
- Bathrooms & en suites
When to call us in Chislet
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.
The most common problems we see are:
- Leaking shower tray seals in a new home
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Joints pulling apart as timber shrinks
In and around Chislet, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- When the joint can take water or movement
- How the surfaces are prepared before sealing

Questions from Chislet
Can you help a landlord with a rental near Herne Bay station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is Chislet 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.
Is the work guaranteed?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Chislet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
