About our new build mastic in Mile End
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. Common call-outs are for joints pulling apart as timber shrinks and frame joints opening as the plaster dries, on windows & doors, bathrooms & en suites and kitchens.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Every job is covered by our 12-month guarantee.

Landlords, agents and businesses in Mile End
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, call 0345 464 0079 or drop us an email with pictures and we’ll give you a straight answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Mile End, the repair is bigger than a sealant job.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.
Why book with us
- White, clear, grey or coloured to suit, where the product allows

New build mastic in Mile End: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Mile End can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near Limehouse station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours in a single home. In Mile End, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Advice
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
- Don’t wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Surface by surface
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 in a matching colour.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Common questions in Mile End
Do you cover Mile End for new build mastic?
Yes. Our work covers London and the South East, and Mile End is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Limehouse station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
What affects the cost of new build mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Whether there’s mould to deal with
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
To help us quote quickly, let us know:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- Any previous sealing or DIY work
