How to look after the new joints
So the new joints stay in good condition:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Sand mastic in Pagham
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We are often asked to deal with patchy fillers round a sash window and tired mastic found when preparing windows for paint, on period & listed homes, tenement windows and brick reveals.
Somewhere as small as Pagham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. In a small place like Pagham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear quote for the lot.

Pagham questions
Do you cover smaller places like Pagham?
Yes, Pagham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Pagham 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.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is sand mastic better than silicone for my windows?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later, and we’ll tell you what to expect.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Somewhere as small as Pagham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

What affects the quote in Pagham
There’s no set price list, because no two jobs are the same. What we look at:
- How many areas need sealing
- How much there is to do
- The type of sealant required
- Any mould that needs treating
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- The problem you’ve noticed
- A few photos by email, if you can
- Whether it’s a home or a business
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or email us.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What else we do in Pagham
What sand mastic looks like in Pagham
Pagham is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much 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 Bognor Regis station, any sash windows need sound mastic to keep draughts and rain out. Schools such as Rose Green Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to The Parish Church of St Thomas A Becket include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
Pagham is about 3 miles south-west of Bognor Regis, in West Sussex. Across the PO21 area, our applicators can take on sand mastic. Pagham is one of 371 places in West Sussex we cover for sand mastic. There’s also a page for Portsmouth, about 15 miles away.
