Window mastic in Stambourne
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before any work starts. To get one, phone 0345 464 0079 or email us with the number of frames and any access details. We work on composite doors, uPVC windows and timber windows & doors, and people most often call us about a bead that doesn’t match the frame and rain getting in at the frame or under the sill.
Around Stambourne, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Common questions in Stambourne
Is Stambourne in your area for window mastic?
Yes, Stambourne is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Stambourne within the area you cover?
Yes, Stambourne 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.
Do you guarantee window mastic?
Yes. Our one-year guarantee covers every job, inside or out.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we’ll choose accordingly.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

What else we do in Stambourne
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Window mastic in Stambourne: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hedingham Castle (about 4.6 miles south-east) are a reminder that the area around Stambourne has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Around Stambourne, as everywhere, window mastic is only as good as the preparation behind it. For an older house near a landmark such as Parish Church of St Peter and St Thomas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that’s a job for a joiner.
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
For anyone letting property in or around Stambourne, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure the drainage slots aren’t blocked
- Ventilate rooms so frames do not stay wet inside
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
Why it’s worth doing now in Stambourne
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Stambourne 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 a few questions first and agree the price before starting.
