About our new build mastic in Acton Vale
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. We’re often asked to deal with sealant work across a run of new homes and cracked sealant around new window and door frames, on show homes, skirting & floors and kitchens.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Acton Vale and beyond.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

When to call us in Acton Vale
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.
The most common problems we see are:
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
- Gaps between new skirting and floors
- Internal frame sealant that has split
Acton Vale is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Acton Vale questions
Is Acton Vale in your area for new build mastic?
Yes. We work across London and the South East, and Acton Vale is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Acton Central station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
How long does new build mastic take?
It depends on the size of the job, but as a guide it takes a few hours in a single home. We will give you a better idea when we quote.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
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.
Do you have insurance?
Yes. Full insurance covers our work.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In a flat in Acton Vale, 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What you get with us
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work
- You choose the colour before work begins

What new build mastic looks like in Acton Vale
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. 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.
If you’ve bought a new home near Acton Central station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Report sealant problems to your builder during the snagging period
- Don’t wait for the house to settle if water is getting through
- Keep photos and emails about snagging items
- Use the extractor fan every time you shower
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
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.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours in a single home, depending on the size of the job.

- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
