About our window mastic in Binscombe
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. We work on patio & French doors, window sills and composite doors, and the jobs we see most are cracked sealant at the sill ends and mastic that’s falling out in pieces.
In a village or hamlet like Binscombe, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Binscombe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Common problems we fix in Binscombe
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Most people get in touch when they notice one of these:
- Whistling draughts around closed windows
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Mastic that is falling out in pieces
Homes close to St John the Evangelist Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Window mastic in Binscombe: local notes
With historic houses such as Loseley Park (about 0.7 miles north-east) nearby, there’s older building stock in the area around Binscombe as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Farncombe station? Then 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 Loseley Fields Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- Mould in or behind the old joints
- How many areas need sealing
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
When you call or email, these details help:
- Pictures of the joints, sent by email
- The type of property
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or send us an email.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- Faulty window hardware
- Draughts through the window seals rather than the frame
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Binscombe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- 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.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
