How the visit works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. For a village or hamlet like Weavers Down, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.

Window mastic in Weavers Down
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on uPVC windows, window sills and aluminium frames, and people most often call us about draughts coming in around windows and doors and a bead that doesn’t match the frame.
Mastic can only go onto a dry, clean joint, so window work in Weavers Down is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

Windows and doors in Weavers Down
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Liphook Church of England Controlled Junior School, larger buildings have plenty of frames, and the mastic around each one ages.

Do you need window mastic in Weavers Down?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Gaps left after new windows were fitted
- Damp patches on the reveal after heavy rain
For landlords with property near Liphook station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Which sealant they’ll use, and why
- How much experience the applicator has
- Whether VAT is included
- When the joint can take water or movement
Why act early in Weavers Down
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Weavers Down, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.

Your questions about window mastic in Weavers Down
Will you come out to Weavers Down?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Liphook station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
Silicone can’t normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- The number and length of the joints
- Whether there’s mould to deal with
- How many areas need sealing
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
When you contact us, it’s useful to know:
- How many joints, rooms or windows are involved
- Where the property is
- Access, such as stairs, a lift or height
- A few photos by email, if you can

How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
