Windows and doors in Ashurst
Ashurst 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’s 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.
Schools such as Foxhills Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Colbury Christ Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Window mastic in Ashurst, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. If you’re dealing with water coming in at the bottom corners of a door and leaking joints at the ends of sills, we can help, on aluminium frames, uPVC windows and timber windows & doors alike.
In a village or hamlet like Ashurst, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard.

What we are called out for in Ashurst
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
Look out for these signs:
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
If you let a flat or house near Ashurst New Forest station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Advice
Why it’s worth doing now in Ashurst
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Ashurst, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
