Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.

Windows and doors in Goosey
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep paint off silicone joints
- Keep timber frames painted
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
FAQs for Goosey
Do you cover smaller places like Goosey?
Yes. Goosey is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Goosey for window mastic?
Yes, Goosey is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can you get sealant to suit coloured frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How the visit works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a morning for a couple of windows and a door. Somewhere like Goosey needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Related advice
Signs you need window mastic in Goosey
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Keep an eye out for these signs:
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
Homes close to Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
