Common questions in East Garston Woodlands
Can you help a landlord with a rental near Hungerford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like East Garston Woodlands?
Yes, East Garston Woodlands is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for a single window, longer for several. We will give you a better idea when we quote.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Are you insured?
Yes. We are fully insured for every job we do.
Why it’s worth doing now in East Garston Woodlands
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around East Garston Woodlands can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

East Garston Woodlands homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St Mary's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.

Advice
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
