What the job involves on each surface
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Sand mastic in Tongham, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We are often asked to deal with old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, on period & listed homes, timber door frames and brick reveals.
In smaller places like Tongham, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Keep modern sealant off the mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. In a smaller place like Tongham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Common problems we fix in Tongham
Timber frames move with the seasons. The movement cracks the mastic little by little.
Look out for any of the following:
- Window mastic to renew ahead of painting
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
For an older house near a landmark such as Church of St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Windows and doors in Tongham
With historic houses such as Wanborough Manor (about 3.1 miles east) nearby, there’s older building stock in the area around Tongham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as St Paul's CofE Infant School & Nursery, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Ash station, any sash windows need sound mastic to keep draughts and rain out.

Your questions about sand mastic in Tongham
Is Tongham within the area you cover?
Yes, Tongham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Ash station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
What guarantee comes with the work?
All our work has a one-year guarantee.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic and newer frames normally get a flexible sealant.

Leave it or put it right?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Tongham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
