New build mastic in Notting Dale
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. Typical jobs include second-fix sealing on new plots and leaking shower tray seals in a new home, on plot handovers, skirting & floors and show homes.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
Our work is backed for twelve months.

Notting Dale: your questions answered
Can you do new build mastic in Notting Dale?
Yes. Our work covers London and the South East, and Notting Dale is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Shepherds Bush station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.

What affects the cost of new build mastic
Your quote is based on your job. We take into account:
- Whether the work is at height
- The type of sealant required
- Whether there’s mould to deal with
- Working hours on commercial sites
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- Roughly how big the job is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Why it’s worth doing now in Notting Dale
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, ring 0345 464 0079 or email us with photos and we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Notting Dale, the repair is bigger than a sealant job.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- A 12-month guarantee on all work
- ARBOMaster approved applicator
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet

DIY sealant or a professional job?
If you are 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 does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots. For a job in Notting Dale, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Different surfaces, different methods
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.

Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Joints and finishes in Notting Dale homes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
As a London address, Notting Dale can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near Shepherds Bush station, the sealant around baths, showers and frames is worth checking in the first year or two.
