How we handle window mastic in Ascot
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for cold air getting in at the frame edge and sealant in the wrong colour for the frame, on composite doors, window sills and patio & French doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ascot is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Do you need window mastic in Ascot?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Draughts coming in around windows and doors
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
Homes close to Church of All Souls include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Honest limits
A few problems are outside what sealant work can do:
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Ascot: your questions answered
Do you cover Ascot for window mastic?
Yes. Our work covers London and the South East, and Ascot is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Ascot?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and businesses?
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.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we’ll choose accordingly.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
How it works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house for a typical job. In a small place like Ascot, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Frames and glazing around Ascot
With historic houses such as St Leonard's Hill (about 4.1 miles north) nearby, there’s older building stock in the area around Ascot as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Ascot station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as South Ascot Village Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Ascot is about 4 miles east of Bracknell, in Windsor and Maidenhead.

What affects the quote in Ascot
For a quick quote, just ask. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Access and height
- When we can work, for business premises
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
To get a quote, call 0345 464 0079 or email us with the location and a short description of the problem. You’ll have a clear quote before work begins.
Why act early in Ascot
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Where a wall is exposed, as many are in small places like Ascot, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
