New build mastic in Hainault, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on skirting & floors, bathrooms & en suites and plot handovers, and common reasons people get in touch are shower seals failing in the first year or two and messy sealant that spoils new finishes. Need a sealant company near Hainault? Mr Mastic covers Hainault, fully insured and ARBOMaster approved.
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.
Each job carries a 12-month guarantee.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Get a leaking seal dealt with right away
- Ventilate bathrooms well, especially in the first year
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
When to call us in Hainault
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Common reasons people contact us are:
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
Hainault is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Which colour the sealant will be
- How long the guarantee is
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Your questions about new build mastic in Hainault
Is parking a problem for a job in Hainault?
Parking in Hainault, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Seven Kings station?
Yes, we work for landlords and letting agents. You can ring 07833 053749 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
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, and we’ll explain our choice.
Do you cover Hainault?
We do. Hainault is part of the area we cover.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long does new build mastic take?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we’ll tell you how long to expect.
How much does new build mastic cost in Hainault?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a flat in Hainault, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 07833 053749 or send us an email.

Joints and finishes in Hainault 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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
For new homes near Seven Kings station, it’s worth checking the sealant early, while snags are still fresh.
