About our window mastic in Ibsley
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for gaps left after new windows were fitted and white mastic on grey or black frames, across window sills, timber windows & doors and composite doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ibsley is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere like Ibsley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Ibsley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Paint up to the joint, not over it
- Look round the frames every year or so
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Common problems we fix in Ibsley
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
These are the problems we’re asked about most:
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
In the older streets around Church of St Martins, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
