New build mastic in Plaistow, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for sealant work across a run of new homes and beads laid onto grit and dust from the build, on kitchens, bathrooms & en suites and plot handovers.
Somewhere as small as Plaistow, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Questions from Plaistow
Is there a guarantee on new build mastic in Plaistow?
All our work, in Plaistow and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Plaistow within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Can I do it myself?
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.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope and we will quote.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Signs you need new build mastic in Plaistow
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
The problems people generally mention when they call include:
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Internal frame sealant that has split
- Gaps between new skirting and floors
In and around Plaistow, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. In a small place like Plaistow, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Quotes for new build mastic in Plaistow
Jobs vary more than people expect. What affects the quote:
- The size of the job
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- When we can work, for business premises
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The address or postcode of the job
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Roughly how big the job is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Settlement cracks that need a surveyor
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

What else we do in Plaistow
The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Plaistow, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- 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.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us if parking is tricky
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
