Windows and doors in Wannock
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Alfriston Clergy House (about 3.4 miles west) nearby, there’s older building stock in the area around Wannock as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Wilfrid include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Polegate station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic for homes and businesses in Wannock
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have mastic worn away on windows facing the weather and crumbling sand mastic round a window, we can put it right, whatever the surface.
In a village or hamlet like Wannock, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work is covered by a 12-month guarantee, wherever you are in East Sussex.

When to call us in Wannock
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they generally need raking out.
It’s worth asking for a quote if you see:
- Mastic dropping out of the joint
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
- Silicone on a period window that looks wrong
If you look after a building such as Willingdon Community School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- How long the guarantee is
- How long to leave it before use
- Whether VAT is included
- What insurance they hold
Leave it or put it right?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Wannock, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.

Wannock questions
Do you cover Wannock for sand mastic?
Yes. We work across London and the South East, and Wannock is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Wannock within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across East Sussex.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes a few hours for a single window, longer for several. In a small place like Wannock, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Keep children and pets away from the work area
- Mention if the joints have been sealed before
- Mention any tricky access

What the job involves on each surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is usually favoured.
Looking after it afterwards
So the new joints stay in good condition:
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
- Don’t run silicone over sand mastic
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
