How we handle sand mastic in Loosley Row
Across Loosley Row, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for crumbling sand mastic round a window and gaps where the frame meets the masonry, on period & listed homes, timber door frames and tenement windows.
Homes in small places like Loosley Row often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Loosley Row and everywhere else we cover.

Why it’s worth doing now in Loosley Row
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Loosley Row, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Frames and glazing around Loosley Row
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as West Wycombe Park House (about 3.9 miles south) nearby, there’s older building stock in the area around Loosley Row 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.
For an older house near a landmark such as Church of St John the Evangelist, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Saunderton station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as St John's Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before we start.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you have insurance?
Yes. Mr Mastic is fully insured.

- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.

Advice
Landlord and commercial work in Loosley Row
Landlords and letting agents in Loosley Row can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Surface by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
