Sand mastic in Wiggonholt: local notes
With historic houses such as Parham House (about 1.5 miles south) nearby, there’s older building stock in the area around Wiggonholt as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Rented homes near Pulborough station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

About our sand mastic in Wiggonholt
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you’re dealing with a silicone bead on a sash window that spoils the look and draughty sash windows at the surround, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Wiggonholt is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with our one-year guarantee, wherever you are in West Sussex.

Should I try it myself first?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
- Don’t run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Do you need sand mastic in Wiggonholt?
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.
If you can see any of these, it’s time to have the joints looked at:
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
For an older house near a landmark such as Wiggonholt Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wiggonholt, 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it possible to paint over sand mastic?

Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is the work guaranteed?

Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Why it’s worth doing now in Wiggonholt
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Wiggonholt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
