What window mastic looks like in Pagham
Pagham 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 is hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Rose Green Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to The Parish Church of St Thomas A Becket include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Bognor Regis station, renewing tired window mastic between tenants heads off draught and damp complaints.
Pagham is about 3 miles south-west of Bognor Regis, in West Sussex. Every kind of property in Pagham can book us for window mastic, old or new, large or small. The work is guaranteed for a year.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Why act early in Pagham
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Pagham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. In a small place like Pagham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, 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
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Related advice
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Pagham: your questions answered
Will you come out to Pagham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Pagham affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee, and we are fully insured.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Pagham, along with the rest of our area.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Walk round the house once a year and look at the joints
- Clear any debris from frame drain holes
- Keep paint off silicone joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
