DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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.
Window mastic for homes and businesses in Rusper
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, timber windows & doors and composite doors, and people most often call us about draughts coming in around windows and doors and cracked internal joints between frame and plaster.
In a village or hamlet like Rusper, 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.
Every job comes with our one-year guarantee, wherever you are in West Sussex.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work normally takes a morning for a couple of windows and a door. Somewhere as small as Rusper, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
How to get a quote

Rusper homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Faygate station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Rusper Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Rusper
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The problems people usually mention when they call are:
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
If you live in an older home near St Mary Magdalene church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Different surfaces, different methods
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Quotes for window mastic in Rusper
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Where a wall is exposed, as many are in small places like Rusper, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
What you get with us
- White, clear, grey or another colour, product permitting
- Experience in homes, commercial sites and hotels
- We are fully insured
- Every job guaranteed for a year
Looking after it afterwards
Looking after new joints is easy:
- Do not paint over the silicone
- Keep timber frames painted
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
