How we handle sand mastic in Bulls Cross
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 are often asked to deal with modern sealant on a period surround and mastic dropping out of the joint, on timber door frames, period & listed homes and brick reveals.
In a village or hamlet like Bulls Cross, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

What else we do in Bulls Cross
Frames and glazing around Bulls Cross
Historic houses like Forty Hall (about 0.7 miles south-west) are a reminder that the area around Bulls Cross 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 is 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.
Schools such as Capel Manor Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Turkey Street station, any sash windows need sound mastic to keep draughts and rain out.

Different surfaces, different methods
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Decayed frames that need repair
- Broken panes
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Stone surrounds
- Sash and case windows
- Tenement windows
- Brick reveals
- Timber door frames
- Period & listed homes
Should I try it myself first?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens on the day
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. In a small place like Bulls Cross, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Do not run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Do you need sand mastic in Bulls Cross?
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Patchy fillers round a sash window
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
For an older house near a landmark such as Jesus Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
