How we handle sand mastic in Ardingly
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We’re often asked to deal with modern sealant on a period surround and patchy fillers round a sash window, across brick reveals, stone surrounds and sash and case windows.
Homes in small places like Ardingly often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a one-year guarantee, the same in Ardingly as everywhere else we work.

Why act early in Ardingly
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Ardingly, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- Any old sealant cut out fully, not covered over
- Arbo and Everbuild products
- We leave the area clean and tidy
- Experience in homes, commercial sites and hotels

Do you need sand mastic in Ardingly?
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
These are the problems we are asked about most:
- Gaps round a timber door in stone or brick
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
- Modern sealant on a period surround
Rented homes near Balcombe station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
- How the colour is chosen
- What insurance they hold
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Inspect the joints round the windows every year or so
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
- Have rotten timber repaired before new mastic goes in
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Landlord and commercial work in Ardingly
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Letting agents and landlords in Ardingly can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere as small as Ardingly, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

What sand mastic looks like in Ardingly
Historic houses like Priest House (about 2.2 miles north-east) are a reminder that the area around Ardingly 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as St Peter's CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Peter's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
