About our new build mastic in North Fambridge
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first. Typical jobs include internal frame sealant that has split and joints pulling apart as timber shrinks, across windows & doors, plot handovers and show homes.
For a small place like North Fambridge, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Somewhere like North Fambridge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- 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.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors to the agreed spec.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Joints and finishes in North Fambridge homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near North Fambridge station, it’s worth checking the sealant early, while snags are still fresh.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few photos and we will give you a straight answer. Older cottages and farmhouses around North Fambridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover North Fambridge and the rest of Essex, along with the rest of our area.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
