About our sand mastic in Shreding Green
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We are often asked to deal with a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, on stone surrounds, sash and case windows and timber door frames.
Somewhere as small as Shreding Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You get a one-year guarantee, the same in Shreding Green as everywhere else we work.

Looking after it afterwards
So the new joints stay in good condition:
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
- 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.
Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Windows and doors in Shreding Green
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. With historic houses such as Windsor Castle (about 4 miles south-west) nearby, there’s older building stock in the area around Shreding Green 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.
In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as The Iver Village Junior School, its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Shreding Green
Common problems we fix in Shreding Green
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
Keep an eye out for any of the following:
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
For landlords with property near Langley station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- Which colour the sealant will be
- What guarantee comes with the work
- Whether VAT is included
- What happens if they find a problem under the old sealant
What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. Somewhere like Shreding Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
