New build mastic for homes and businesses in Cannon's Green
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Typical jobs include cracks appearing as a new home settles and frame joints opening as the plaster dries, on skirting & floors, show homes and plot handovers.
For a small place like Cannon's Green, the journey and access are planned in advance, and the work itself is the same as on any site.
All our work is covered by our one-year guarantee, wherever you are in Essex.

What else we do in Cannon's Green
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Common problems we fix in Cannon's Green
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
For jobs in and around Cannon's Green, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- What happens if the job turns out different
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- Which sealant they’ll use, and why
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Cannon's Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Why us?
- You choose the colour before work begins
- A 12-month guarantee on all work

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Follow the cure time we give you
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you are covered
- Clean sealant with mild detergent, not abrasives
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.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
