New Build Mastic in Broomhall
New-build sealant joints in Broomhall need attention? We cut out the old, prepare the joints and apply the right sealant.
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
New build mastic in Broomhall, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on windows & doors, bathrooms & en suites and kitchens, and people most often call us about second-fix sealing on new plots and cracked sealant around new window and door frames.
In smaller places like Broomhall, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
A one-year guarantee comes as standard.

When it is not the sealant

Do you need new build mastic in Broomhall?
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Signs it’s time to call us include:
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
For new homes near Sunningdale station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints
To keep the joints looking good and working properly:
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
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.
