About our sand mastic in Tolworth
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on sash and case windows, timber door frames and tenement windows, and people most often call us about draughts and rain around sash boxes and old cement repairs round a window that have failed.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Tolworth.
Whatever the size of the job, you get the same 12-month guarantee in Tolworth and across Greater London.

Windows and doors in Tolworth
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.

Signs you need sand mastic in Tolworth
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Common reasons people contact us are:
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
- Modern sealant on a period surround
- Cracked mastic round a front door frame
Rented homes near Tolworth station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

For landlords and businesses
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How we quote for sand mastic
The quote reflects the job in front of us. We take into account:
- Whether the work is at height
- The number of rooms or windows
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If someone has resealed it before
- The type of property
We quote each job on its own. Just call 0345 464 0079 or email us with the details.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a single window, longer for several. In Tolworth, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- 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
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Related advice
What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. In a flat in Tolworth, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
