About our window mastic in North Fareham
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include sealant in the wrong colour for the frame and rain getting in at the frame or under the sill, across timber windows & doors, composite doors and aluminium frames.
In a village or hamlet like North Fareham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Common problems we fix in North Fareham
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Any of these means the joints need attention:
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
If you let a flat or house near Fareham station, renewing tired window mastic between tenants heads off draught and damp complaints.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Somewhere like North Fareham 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 confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Clear the area around the work
- Mention any tricky access
- Tell us if parking is tricky

Advice
Frames and glazing around North Fareham
North Fareham is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Harrison Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Parish Church of St Peter and St Paul include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Your questions about window mastic in North Fareham
Do you cover smaller places like North Fareham?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in North Fareham?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you seal inside as well as outside?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Air rooms to keep condensation down around windows
- Keep solvents and bleach off the sealant
- Repaint timber before it’s bare
- Avoid blasting the frames with a pressure washer
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
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.
Why it’s worth doing now in North Fareham
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around North Fareham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
