About our new build mastic in Brook
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you are dealing with shower seals failing in the first year or two and beads laid onto grit and dust from the build, we can put it right.
Older homes in small places like Brook often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months.

Aftercare tips
To keep the joints looking good and working properly:
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Signs you need new build mastic in Brook
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Common reasons people contact us include:
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Internal frame sealant that has split
- Smeared, uneven beads picked up at snagging
In and around Brook, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal cannot. If you’re unsure which you have, ring 0345 464 0079 or drop us an email with pictures and we will give you a straight answer. Around Brook, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Joints and finishes in Brook homes
Brook is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For jobs in and around Brook, choosing the right material for each joint is as important as a tidy finish.

What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Cracked trays, tiles or worktops

- Structural cracks in walls or ceilings

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. Somewhere as small as Brook, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- 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.
Preparing for the visit
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
