- Shower seals failing in the first year or two
New build mastic in Bush Hill
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for joints pulling apart as timber shrinks and leaking shower tray seals in a new home, on plot handovers, bathrooms & en suites and windows & doors.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How long will you be here?

Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.

Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room before we begin.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
Surfaces we seal
- Bathrooms & en suites
- Kitchens
- Plot handovers
- Show homes
- Skirting & floors
- Windows & doors
Signs you need new build mastic in Bush Hill
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
These are the problems we’re asked about most:
- Sealant work across a run of new homes
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
Bush Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- The length of the guarantee
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- How long to leave it before use
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home. For a job in Bush Hill, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Clear the area around the work
- Mention any tricky access
- Keep children and pets away from the work area

Joints and finishes in Bush Hill homes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Grange Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

Aftercare tips
A little care helps the new joints last. Our advice:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Keep photos and emails about snagging items
- Follow the cure time we give you
Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
Why it’s worth doing now in Bush Hill
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Can I do it myself?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Bush Hill and across Greater London. Several sites can be quoted together, and we are fully insured.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
