Window mastic for homes and businesses in Winchfield
Around Winchfield we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on patio & French doors, composite doors and window sills, and common reasons people get in touch are cold air getting in at the frame edge and sealant in the wrong colour for the frame.
Around Winchfield, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a one-year guarantee, the same in Winchfield as everywhere else we work.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes most of a day for a typical house, less for a few frames. Somewhere like Winchfield needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Leave it or put it right?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Older cottages and farmhouses around Winchfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Soft or decayed wood in the frame
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Window mastic in Winchfield: local notes
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.
Homes close to Church of St Mary the Virgin include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Winchfield station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Winchfield: your questions answered
Will you come out to Winchfield?
Yes. Winchfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Winchfield station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Do you need window mastic in Winchfield?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Look out for these signs:
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
If you look after a building such as Oakwood Infant School, larger buildings have plenty of frames, and the mastic around each one ages.
