Window & door mastic in Westmeston, West Sussex
We cover Westmeston for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
How we handle window mastic in Westmeston
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Common call-outs are for water coming in at the bottom corners of a door and old mastic that has gone black or come away, across timber windows & doors, composite doors and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Westmeston is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a one-year guarantee, wherever you are in West Sussex.

Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Windows and doors in Westmeston
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Preston Manor & Gardens (about 4.9 miles south-west) nearby, there’s older building stock in the area around Westmeston as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Ditchling (St Margaret's) Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Hassocks station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around The Parish Church of St Martin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
Silicone cannot generally be painted, so mention any painting plans before we start. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Why act early in Westmeston
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Westmeston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Westmeston questions
Will you come out to Westmeston?
Yes, Westmeston is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Hassocks station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before any work starts.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Westmeston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
