How we handle new build mastic in Crockham Heath
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include new-build shower sealant that has already split and cracks appearing as a new home settles, on skirting & floors, show homes and kitchens.
Older homes in small places like Crockham Heath often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

Why act early in Crockham Heath
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a small place like Crockham Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Is Crockham Heath within the area you cover?

Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long does the job take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.

Advice
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Landlord and commercial work in Crockham Heath

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
- Don’t seal over failed sealant yourself
- Record problems with dated photos
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
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.
