Sand mastic for homes and businesses in Aldington
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We work on tenement windows, period & listed homes and sash and case windows, and the jobs we see most are draughty sash windows at the surround and window mastic to renew ahead of painting.
In a village or hamlet like Aldington, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Every job is covered by a 12-month guarantee, wherever you are in Kent.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a single window, longer for several, depending on how much there is to do. Somewhere as small as Aldington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

What sand mastic looks like in Aldington
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. Historic houses like Westenhanger Castle (about 3.9 miles east) are a reminder that the area around Aldington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of St Martin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Ham Street station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How to look after the new joints
Aftercare is simple:
- Ask the planning authority about consent for listed or conservation-area homes
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Aldington: your questions answered
Will you come out to Aldington?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do sand mastic in Aldington?
Yes, Aldington is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long will you be here?
Most jobs take a few hours per window, depending on the condition of the joints, including preparation and clearing up. We’ll confirm how long when we quote.
What guarantee comes with the work?
All our work has a 12-month guarantee.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

Look out for these signs:
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
