About our sand mastic in Bognor Regis
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. Typical jobs include tired mastic found when preparing windows for paint and cracked mastic round a front door frame, across brick reveals, sash and case windows and period & listed homes.
Plenty of homes in Bognor Regis are rented, and windows are easy to overlook between tenancies. Gaps around a frame let in draughts and water, and tenants notice.
We stand behind the work with a 12-month guarantee.

How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Commercial jobs in Bognor Regis can be planned out of hours where a building can’t close, and homes are booked within our usual hours, Monday to Saturday.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Mention if the joints have been sealed before

Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sand mastic in Bognor Regis: local notes
Bognor Regis 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. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Mary Magdalene, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Bognor Regis station? Then any sash windows need sound mastic to keep draughts and rain out.

What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It will not solve:
- Masonry that needs repairing
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Sash and case windows
- Tenement windows
- Period & listed homes
- Stone surrounds
- Brick reveals
- Timber door frames
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Get any rot dealt with first
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Common problems we fix in Bognor Regis
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
Managing a site like The Regis School? Then its window and door frames need their mastic kept sound, just like a home’s.
