About our new build mastic in Bocking
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on show homes, bathrooms & en suites and plot handovers, and people most often call us about sealant applied over dusty or wet surfaces and internal frame sealant that has split.
Homes around Bocking range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Our work is backed for twelve months, in Bocking and everywhere else we cover.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.

How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. A visit to Bocking is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
How to get a quote
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.
Related advice
What we’re called out for in Bocking
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Common reasons people contact us include:
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Braintree station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Who does the work, and how experienced they are
- What insurance they hold
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Homes in smaller places like Bocking can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Why book with us
- One-year guarantee on every job
- Any old sealant cut out fully, not covered over

DIY versus a professional finish
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
