New build mastic for homes and businesses in South Street
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have internal frame sealant that has split and smeared, uneven beads picked up at snagging, we can put it right, on windows & doors, bathrooms & en suites and skirting & floors alike.
Around South Street, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with a one-year guarantee, wherever you are in Kent.

Signs you need new build mastic in South Street
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 before the sealant goes on.
The problems people usually mention when they call include:
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
For new homes near Meopham station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking

- How long the guarantee is

Your questions about new build mastic in South Street
Will you come out to South Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Meopham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover South Street, along with the rest of our area.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
How we quote for new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises
- How many areas need sealing
- Whether the work is at height
- The product the joint needs
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
What to tell us for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- What’s wrong with the joints now
For new build mastic in South Street, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Settlement cracks that need a surveyor
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours in a single home, and we explain the cure time before we leave. Somewhere like South Street 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.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Move anything stored near the joints
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around South Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
