Window mastic in Hunton
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include a bead that doesn’t match the frame and whistling draughts around closed windows, on patio & French doors, window sills and aluminium frames.
In a village or hamlet like Hunton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
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.

When it isn’t the sealant
It helps to know what we can’t do:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- A sash or casement that won’t close properly

How we quote for window mastic
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The number and length of the joints
- Working hours on commercial sites
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. The price is agreed before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- The address or postcode of the job
- Any access issues, like height or stairs
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
Do you need window mastic in Hunton?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
People usually contact us after spotting one of these:
- Gaps left after new windows were fitted
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
- Black, perished sealant on frames
If you live in an older home near Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Hunton
Can you do window mastic in Hunton?
Yes, Hunton is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Micheldever station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. In a small place like Hunton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Every joint is checked before we leave.
How to prepare
- Tell us if parking is tricky
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Landlords, agents and businesses in Hunton
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Why act early in Hunton
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Older cottages and farmhouses around Hunton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- An ARBOMaster approved applicator
- We’re fully insured
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
