How we handle new build mastic in Liverton Street
We work in new homes and on new-build sites across Liverton Street. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, across windows & doors, plot handovers and bathrooms & en suites.
For a small place like Liverton Street, the journey and access are planned in advance, and the work itself is the same as on any site.
Every job comes with a one-year guarantee.

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you are covered
- Photograph failed sealant before it’s redone
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

Liverton Street: your questions answered
Is Liverton Street in your area for new build mastic?
Yes. Our work covers London and the South East, and Liverton Street is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you help a landlord with a rental near Lenham station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Why does sealant fail so quickly in new builds?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we’re happy to quote and our work is guaranteed for a year.

Related advice
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Liverton Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
