Sand mastic in Slough: how it works

Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on timber door frames, stone surrounds and tenement windows, and people most often call us about cracked mastic round a front door frame and crumbling sand mastic round a window.

There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows.

Each surround is checked first.
The joint is raked out and cleaned.
Large voids are packed out.
We point the joint with sand mastic by hand.
The finish is dressed neatly.

What you’ll pay

Doing several joints on 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.

Sand mastic across Slough: local notes

Across Slough, from Cippenham, Chalvey and Britwell outwards, frames range from older timber to modern uPVC and aluminium. The mastic around all of them ages, and it’s generally the first thing to let the weather in.

Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in Slough, surfaces are cleaned back properly before new sealant goes in.

Slough: If you live in an older home near St Michael and All Angels, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Herschel Grammar School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why act early?

Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put.

Common problems we fix in Slough

Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.

The problems people usually mention when they call include:

Wind and rain getting in round a sash window
Silicone on a period window that looks wrong
Gaps where the frame meets the masonry
Gaps round a timber door in stone or brick

What sealant work cannot fix

Before booking, it’s worth knowing the limits too:

Rotten sashes, sills or window boxes (a joiner’s job)
Broken panes
Decisions on consent for listed homes

Common questions in Slough

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Where is Mr Mastic based?

Our base is in Crawley, and we work across South East England, London and Scotland.

When will the new mastic be hard?

The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.

Can I choose the sealant colour?

In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before any work starts.

Do you do commercial work?

Yes. We have worked for hotels, offices and other businesses, and we are fully insured.

Are you fully insured?

Yes. Full insurance covers our work.

Can I paint the new mastic?

Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
