How we handle window mastic in Townhill Park
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with rain getting in at the frame or under the sill and untidy mastic left by window fitters, across aluminium frames, composite doors and uPVC windows.
In a smaller place like Townhill Park, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Make sure the drainage slots aren’t blocked
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

Windows and doors in Townhill Park
Historic houses like South Stoneham House (about 0.9 miles north-west) are a reminder that the area around Townhill Park has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as Townhill Junior School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Swaythling station, renewing tired window mastic between tenants heads off draught and damp complaints.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. Parking around Townhill Park is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear items away from the joints we are working on
- Mention any tricky access
- Try not to wet indoor joints just before the visit

When it is not the sealant
New sealant can’t fix everything, and we will tell you before any work starts. Sealant won’t put right:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Signs you need window mastic in Townhill Park
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That is what backing rod is for.
People generally contact us after spotting something like this:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- A bead that doesn’t match the frame
- Rushed sealant from a window installation
For an older house near a landmark such as St. Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
