New build mastic in Mill Corner, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on plot handovers, show homes and kitchens, and people most often call us about sealant applied over dusty or wet surfaces and plot mastic for developers ahead of handover.
For a small place like Mill Corner, the journey and access are planned in advance, and the work itself is the same as on any site.
You get a one-year guarantee, the same in Mill Corner as everywhere else we work.

When to call us in Mill Corner
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
The problems people normally mention when they call are:
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
In and around Mill Corner, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Don’t seal over failed sealant yourself
- Keep pictures and emails about snagging items
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
FAQs for Mill Corner
Can you do new build mastic in Mill Corner?
Yes. Our work covers London and the South East, and Mill Corner is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you cover smaller places like Mill Corner?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do you have insurance?
Yes. We are fully insured.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Advice
What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- How easy the joints are to reach
- The product the joint needs
- How many rooms, windows or areas are involved
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
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, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
