Sand Mastic in Wimbledon Chase
Specialist sand mastic for Wimbledon Chase: careful preparation, the right product and tidy work. Call for a quick quote.
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
- Mastic that needs renewing before redecorating
Looking after it afterwards
After the cure time, these simple habits help:
- Avoid heavy scraping on the mastic joint
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Sand mastic in Wimbledon Chase, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have draughty sash windows at the surround and silicone on a period window that looks wrong, we can put it right.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Wimbledon Chase as anywhere.
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.

Wimbledon Chase homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
As a London address, Wimbledon Chase can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Homes close to St Mary's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Advice
Common questions in Wimbledon Chase
I let a flat near Wimbledon Chase station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is parking a problem for a job in Wimbledon Chase?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
How long does the job take?
That depends on the amount of work, but most jobs take anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick generally suit sand mastic and newer frames generally get a flexible sealant.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.

Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.

Surface by surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.

- If it’s domestic, commercial or a hotel
- Where the property is

When to call us in Wimbledon Chase
Rain on the window surround works into any crack and pushes it out. Exposed elevations usually fail first.
If you can see any of these, it’s time to have the joints looked at:
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
- Patchy fillers round a sash window
- Open joints round the window box
Rented homes near Wimbledon Chase station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
