How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows.

Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

Advice
Sand mastic for homes and businesses in Cryers Hill
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, brick reveals and timber door frames, and people most often call us about a silicone bead on a sash window that spoils the look and cement or filler used on old window joints that has cracked.
Somewhere as small as Cryers Hill, 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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Different surfaces, different methods
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Do you need sand mastic in Cryers Hill?
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice one of these:
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
For landlords with property near High Wycombe station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before you book
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Who does the work, and how experienced they are
- When the joint can take water or movement
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Cryers Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Sand mastic in Cryers Hill: local notes
Historic houses like Hughenden Manor (about 1.3 miles south-west) are a reminder that the area around Cryers Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
For site and facilities teams at buildings such as Great Kingshill Church of England Combined School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of the Good Shepherd, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Do the sealants smell?

Is it possible to take out silicone and use sand mastic instead?
Generally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
