Willey Green questions
Is Willey Green in your area for sand mastic?
Yes. We work across London and the South East, and Willey Green is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Willey Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Are you fully insured?
Yes, we are fully insured.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Sand mastic in Willey Green
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. We work on timber door frames, tenement windows and sash and case windows, and people most often call us about gaps round a timber door in stone or brick and wind and rain getting in round a sash window.
In a village or hamlet like Willey Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Windows and doors in Willey 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 Wanborough Manor (about 1.8 miles south) nearby, there’s older building stock in the area around Willey Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St Mark, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Kings College Guildford, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Wanborough station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

What affects the quote in Willey Green
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- How easy the joints are to reach
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
To help us quote quickly, let us know:
- Roughly how big the job is
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
For sand mastic in Willey Green, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Older cottages and farmhouses around Willey Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

- Whether work needs listed building consent
