New build mastic in Poyle
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for shower seals failing in the first year or two and gaps behind new kitchen upstands, on skirting & floors, windows & doors and plot handovers.
Older homes in small places like Poyle often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with our one-year guarantee, wherever you are in Slough.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Check bath and shower seals every few months as the house settles
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you are covered
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Advice
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Poyle, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

Signs you need new build mastic in Poyle
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Keep an eye out for these signs:
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
For new homes near Heathrow Terminal 5 Rail station, it’s worth checking the sealant early, while snags are still fresh.

Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish.
My new home is still under warranty. Should I contact you?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
