Hursley Window Mastic
Window and door frames in Hursley need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Mastic that is falling out in pieces
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
How we handle window mastic in Hursley
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have untidy mastic left by window fitters and draughty joints inside around the window, we can help, on uPVC windows, patio & French doors and aluminium frames alike.
Mastic can only go onto a dry, clean joint, so window work in Hursley is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. 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 Hursley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

FAQs for Hursley
Will you come out to Hursley?
Yes. Hursley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Hursley?
Yes, Hursley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How much does window mastic cost in Hursley?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Hursley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip 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.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear the area around the work
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
- Composite doors
- Window sills
- Timber windows & doors
Do you need window mastic in Hursley?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Any of these means the joints need attention:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
For landlords with property near Shawford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include
- Whether you can choose the colour
- What preparation is included
- Whether VAT is included
- When the joint can take water or movement
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid blasting the frames with a pressure washer
- Do not paint over the silicone
- Make sure the drainage slots aren’t blocked
- Keep timber frames painted
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What else we do in Hursley
Window mastic in Hursley: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as John Keble Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
