About our new build mastic in Monk Street
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on windows & doors, show homes and plot handovers, and common reasons people get in touch are new-build shower sealant that has already split and joints pulling apart as timber shrinks.
Around Monk Street, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a 12-month guarantee, the same in Monk Street as everywhere else we work.

New build mastic in Monk Street: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Stansted Airport station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
Do you need new build mastic in Monk Street?
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Most people get in touch when they notice one of these:
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
Around Monk Street, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- When the joint can take water or movement
- What preparation is included
- How much experience the applicator has
- Whether VAT is included
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you’re unsure which you have, ring 0345 464 0079 or email us with pictures. Older cottages and farmhouses around Monk Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Monk Street, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
