Around South Ascot we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills.

Homes around South Ascot range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.

Common questions in South Ascot
Do you cover South Ascot for window mastic?
Yes, South Ascot is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Will you come out to South Ascot?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like South Ascot, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Tell us if parking is tricky

Surface by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Why act early in South Ascot
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Around South Ascot, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Why us?

Signs you need window mastic in South Ascot
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Keep an eye out for any of the following:
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
Homes close to Church of All Souls include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone
- Whether they seal over old material or remove it
- When the joint can take water or movement
- Whether they’re fully insured

South Ascot homes and the weather
Historic houses like St Leonard's Hill (about 4.8 miles north) are a reminder that the area around South Ascot has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Ascot station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as St Francis Catholic Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
