Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Damaged stone surrounds
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

About our sand mastic in Marden Beech
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. We work on period & listed homes, tenement windows and brick reveals, and people most often call us about modern sealant on a period surround and old cement repairs round a window that have failed.
Mastic can only go onto a dry, clean joint, so window work in Marden Beech is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Marden Beech as everywhere else we work.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Marden Beech: your questions answered
Is Marden Beech within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Marden station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint

- The type of property
- How many joints, rooms or windows are involved

What sand mastic looks like in Marden Beech
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Marden Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Marden station, any sash windows need sound mastic to keep draughts and rain out.

How it works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints. Somewhere like Marden Beech needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Signs you need sand mastic in Marden Beech

Signs it’s time to call us include:
- Gaps between timber frames and stone or brick
- Old cement repairs round a window that have failed
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
For an older house near a landmark such as St Michael and All Angels Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
