Landlords, agents and businesses in Westdene
Landlords and agents in Westdene can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Window mastic in Westdene
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 deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Typical jobs include cracked or shrunken mastic around the frame and gaps between the frame and the inside reveal, on timber windows & doors, aluminium frames and composite doors.
In smaller places like Westdene, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house. For a job in Westdene, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Homes in smaller places like Westdene can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit usually 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 quote for the lot.

Looking after it afterwards
So the new joints stay in good condition:
- Keep paint and stain on wooden frames in good order
- Wipe condensation off the frames
- Clear any debris from frame drain holes
- Look round the frames every year or so
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

When to call us in Westdene
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Mastic that is falling out in pieces
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
If you let a flat or house near Preston Park station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Westdene: local notes
Westdene 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of 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 look after a building such as Westdene Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of the Ascension include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Westdene: your questions answered
Does the coastal weather in Westdene affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Preston Park station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is the new sealant paintable?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
