Why act early in Millbank
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Around Millbank, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

New build mastic in Millbank, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with cracked caulk along new skirting and worktop and upstand sealant coming away, we can put it right, whatever the surface.
For a small place like Millbank, the journey and access are planned in advance, and the work itself is the same as on any site.
Each job carries a 12-month guarantee, large or small.

New build mastic in Millbank: local notes
Millbank is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Millbank, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, 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: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Plumbing faults behind the sealant
- 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 drop us an email and we’ll tell you honestly.

Common questions in Millbank
Do you work for landlords with property near Herne Bay station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Is Millbank in your area for new build mastic?
Yes. Our work covers London and the South East, and Millbank is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Landlords, agents and businesses in Millbank
We also work for property managers and facilities teams in Millbank and across Kent. We can quote a run of properties together, and we are fully insured for the work.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Do you need new build mastic in Millbank?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
The problems people normally mention when they call are:
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces
For new homes near Herne Bay station, it’s worth checking the sealant early, while snags are still fresh.
