Sand mastic for sash & case windows in Woodford, Greater London
We cover Woodford for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
- Draughty sash windows at the surround
How we handle sand mastic in Woodford
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have weathered mastic on the most exposed windows and old cement repairs round a window that have failed, we can help, on stone surrounds, timber door frames and brick reveals alike.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Stone surrounds
We take care not to mark the stone when the old mastic comes out.
What sand mastic looks like in Woodford
With historic houses such as Valentines Mansion (about 2.7 miles south-east) nearby, there’s older building stock in the area around Woodford 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Highams Park station change hands often, and any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Barnabas' Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Woodbridge High School, its window and door frames need their mastic kept sound, just like a home’s.

Questions from Woodford
Do you cover Woodford for sand mastic?
Yes, Woodford is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is parking a problem for a job in Woodford?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Sashes that need overhauling
- Putty and glazing repairs
- Decayed frames that need repair
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Brick reveals
- Period & listed homes
- Sash and case windows
- Timber door frames
How to look after the new joints
So the new joints stay in good condition:
- Sort the mastic before the decorators arrive
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
