Can you help a landlord with a rental near Wokingham station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Yes, Holme Green is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Why act early in Holme Green
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around Holme Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Letting a property close to Wokingham station? Then any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Sebastian's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Advice
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need sand mastic in Holme Green
Rain on the window surround works into any crack and pushes it out. Exposed elevations generally fail first.
Any of these means the joints need attention:
- Draughts and rain around sash boxes
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
Schools such as Floreat Montague Park Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- What happens if the job turns out different
- Whether all the old sealant comes out first
- How much experience the applicator has
- What insurance they hold

When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Timber that has rotted
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
