Sand mastic in South Bersted, done properly
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Typical jobs include silicone on a period window that looks wrong and window mastic to renew ahead of painting, across brick reveals, period & listed homes and sash and case windows.
Houses in smaller places like South Bersted can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
What we can’t put right
It helps to know what we cannot do too:
- Timber that has rotted
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or will not open
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Where we work in South Bersted
- Period & listed homes
- Timber door frames
- Sash and case windows
- Tenement windows
- Stone surrounds
- Brick reveals
What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints for a typical job. Parking around South Bersted is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
How the job changes by surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.

Questions from South Bersted
Will you come out to South Bersted?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Bognor Regis station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
How long does sand mastic take to go off?
Not right away. It skins first and hardens fully later and we will give you an idea for your job.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In an older home around South Bersted, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

- 20+ years of sealant experience

What sand mastic looks like in South Bersted
South Bersted is close to 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. 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 generally the first place rain gets in. Letting a property close to Bognor Regis station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as South Bersted CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
