- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.

About our new build mastic in Barking Riverside
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We’re often asked to deal with smeared, uneven beads picked up at snagging and gaps opening as the house dries out and settles, on show homes, plot handovers and bathrooms & en suites.
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, in Barking Riverside and beyond.
Each job carries a 12-month guarantee, whatever its size.

New build mastic around Barking Riverside
Rainfall in the South East is lower than in much of the UK, 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.
For new homes near Barking Riverside station, it’s worth checking the sealant early, while snags are still fresh.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check bath and shower seals every few months as the house settles
- Avoid running a DIY bead over the old one
- Clean sealant with mild detergent, not abrasives
- Record problems with dated photos
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Baths and trays that move too much for sealant to cope with
- Disputes or warranty claims with your builder
- Broken tiles or a split tray
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

Barking Riverside questions
Is parking a problem for a job in Barking Riverside?
Parking in Barking Riverside, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Barking Riverside station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Why has my new-build shower seal failed already?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
When to call us in Barking Riverside
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Signs it’s time to call us include:
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Internal frame sealant that has split
As a London address, Barking Riverside can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- How much experience the applicator has
- Whether the sealant suits the joint
- The length of the guarantee
- What happens if the job turns out different
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Barking Riverside, the repair is bigger than a sealant job.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Barking Riverside
- Anti-fungal silicone where joints get wet
- Sealant colour chosen to suit
- We agree the colour with you first
- Arbo and Everbuild products

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
