How we handle new build mastic in The 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. Common call-outs are for beads laid onto grit and dust from the build and second-fix sealing on new plots, on windows & doors, kitchens and skirting & floors.
In a village or hamlet like The Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same 12-month guarantee.

What we can’t put right

Landlords and agents in The Green can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Your questions about new build mastic in The Green
Do you cover smaller places like The Green?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Cressing station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you work for developers?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope and we’ll quote.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.

Why it’s worth doing now in The Green
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around The Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours in a single home. In a small place like The Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
