Canning Town New Build Mastic
We cover Canning Town for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
- Sealant that never bonded to the surface
New build mastic for homes and businesses in Canning Town
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you’re dealing with sealant that never bonded to the surface and shower seals failing in the first year or two, we can help, on plot handovers, kitchens and show homes alike.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

- Mould in or behind the old joints

How to look after the new joints
A little care helps the new joints last. Our advice:
- Wipe joints with warm soapy water
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Questions from Canning Town
Is Canning Town in your area for new build mastic?
Yes, Canning Town is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Is parking an issue for new build mastic in Canning Town?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Show homes
- Windows & doors
- Plot handovers
Signs you need new build mastic in Canning Town
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Keep an eye out for these signs:
- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
Canning Town is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
