Window mastic in Durley Street, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on timber windows & doors, window sills and uPVC windows, and common reasons people get in touch are white mastic on grey or black frames and damp patches on the reveal after heavy rain.
Mastic can only go onto a dry, clean joint, so window work in Durley Street is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need window mastic in Durley Street?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- White mastic on grey or black frames
- Untidy mastic left by window fitters
If you let a flat or house near Hedge End station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Durley Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure the drainage slots are not blocked
- Clean frames with a soft cloth and soapy water
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
