New build mastic for homes and businesses in Leverstock Green
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on windows & doors, kitchens and skirting & floors, and the jobs we see most are cracked sealant around new window and door frames and kitchen sealant that has pulled off the wall.
Homes around Leverstock Green range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
All our work is covered by our 12-month guarantee.

How the visit works

A visit to Leverstock Green is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.

Advice
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

New build mastic around Leverstock Green
Hemel Hempstead, which Leverstock Green is part of, is one of England’s post-war new towns. Hemel Hempstead has kept growing, with newer neighbourhoods added to the original town. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Leverstock Green, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Apsley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Questions from Leverstock Green
Can you do new build mastic in Leverstock Green?
Yes. We work across London and the South East, and Leverstock Green is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Apsley station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
How long will you be here?
Typically it takes a few hours in a single home. Bigger jobs take longer.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. In an older home around Leverstock Green, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Anti-fungal silicone where joints get wet
- We agree the colour with you first
- Any old sealant cut out fully, not covered over
- Colour picked to suit the job

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Landlords, agents and businesses in Leverstock Green
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
If you manage several properties in or around Leverstock Green, several properties can go on one quote. Just tell us the addresses and what each one needs.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
- Act quickly if a seal starts to leak
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
