Tyburn New Build Mastic
Problem with your new-build sealant joints in Tyburn? We remove the old material, prepare the joints and seal them properly.

- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
New build mastic in Tyburn, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with skirting joints opening in the first winter and leaking shower tray seals in a new home, we can help, on bathrooms & en suites, kitchens and windows & doors alike.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
You get a 12-month guarantee, the same in Tyburn as everywhere else we work.

New build mastic around Tyburn
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
As a London address, Tyburn can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near London Paddington station, it’s worth checking the sealant early, while snags are still fresh.

If the building has a concierge, managing agent or access rules, tell us when you book.

Advice
Why it’s worth doing now in Tyburn
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. 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.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Surface by surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Your questions about new build mastic in Tyburn
Can you help a landlord with a rental near London Paddington station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Tyburn for new build mastic?
Yes, Tyburn is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
What affects the quote in Tyburn
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- The number and length of the joints
- Access and height
- The type of sealant required
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before work begins.

Keeping the joints in good condition
Aftercare is simple:
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
