Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
New build mastic for homes and businesses in Whyteleafe
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We work on show homes, windows & doors and kitchens, and the jobs we see most are gaps between new skirting and floors and sealant that never bonded to the surface.
Older homes in small places like Whyteleafe often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
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.

Do you need new build mastic in Whyteleafe?
Sealant applied onto damp surfaces doesn’t bond well. Site programmes do not always leave time for joints to dry before the sealant goes on.
Most people get in touch after spotting one of these:
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
Around Whyteleafe, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Whyteleafe 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.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Looking after it afterwards
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Plumbing faults behind the sealant
- Movement caused by a poorly fitted tray or bath
- Cracked trays, tiles or worktops
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
