Window & door mastic in Fishbourne, West Sussex
Our applicators work in Fishbourne on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- A bead that does not match the frame
What we do, step by step
Once we are on site, we check the joints match what you told us. 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. A visit to Fishbourne is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Let us know about parking restrictions
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Advice
Window mastic for homes and businesses in Fishbourne
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have untidy mastic left by window fitters and whistling draughts around closed windows, we can help, on composite doors, uPVC windows and timber windows & doors alike.
In smaller places like Fishbourne, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A door that needs adjusting, rehanging or new seals
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Surfaces we seal

- Composite doors
What we are called out for in Fishbourne
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The most common problems we see are:
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Draughty joints inside around the window
Managing a site like Fishbourne CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- How the joint is cleaned and prepared
- How the colour is chosen
- Whether all the old sealant comes out first
- What guarantee comes with the work
Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Fishbourne homes and the weather
Fishbourne is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Goodwood House (about 3.9 miles north-east) nearby, there’s older building stock in the area around Fishbourne 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.
Homes close to Church of St Peter and St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Fishbourne station, renewing tired window mastic between tenants heads off draught and damp complaints.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Fishbourne: your questions answered
Do you work for landlords with property near Fishbourne station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Does the coastal weather in Fishbourne affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit. We confirm the timing with your quote.
Aftercare tips
To keep the joints looking good and working properly:
- Clear any debris from frame drain holes
- Keep timber frames painted
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
