Window mastic in Friday Street, done properly
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with white mastic on grey or black frames and rushed sealant from a window installation, we can put it right.
Homes in small places like Friday Street often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard.

Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Friday Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
- Do not use solvent cleaners on the joint
- Do not paint over the silicone
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 a cold room gets colder. A new joint closes it up.
What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- Draughts through the window seals rather than the frame
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

What else we do in Friday Street
What we’re called out for in Friday Street
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
People usually contact us when they notice something like this:
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
Letting a property close to Gomshall station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- Is VAT in the price?
- What insurance they hold
- How long to leave it before use
- What happens if they find a problem under the old sealant
Questions from Friday Street
Do you cover Friday Street for window mastic?
Yes. Our work covers London and the South East, and Friday Street is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is Friday Street within the area you cover?
Yes, Friday Street is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.

Yes. We work for householders, landlords, letting agents, businesses and hotels in Friday Street.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.

Windows and doors in Friday Street
Historic houses like Polesden Lacey (about 4.2 miles north) are a reminder that the area around Friday Street has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
For an older house near a landmark such as Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Belmont Prep School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
