Window & door mastic in Easton, Hampshire
Mastic around window and door frames, sills and patio doors for homes and businesses in Easton and across Hampshire. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps where the sill meets the wall
- Rushed sealant from a window installation
- White mastic on grey or black frames
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep paint and stain on wooden frames in good order
- Wipe condensation off the frames
- Make sure the drainage slots aren’t blocked
- Clean frames with a soft cloth and soapy water
Silicone cannot usually be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Window mastic for homes and businesses in Easton
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. If you’re dealing with gaps where the sill meets the wall and rain getting in at the frame or under the sill, we can help, on composite doors, timber windows & doors and window sills alike.
In a village or hamlet like Easton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

Easton: your questions answered
Do you work for landlords with property near Winchester station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is Easton within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
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 you have sealant for grey or black windows?
Generally, yes. Mention the frame colour when you ask for a quote and we will use the nearest match.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Surface by surface
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Signs you need window mastic in Easton
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Any of these means the joints need attention:
- Cold air getting in at the frame edge
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
For landlords with property near Winchester station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
Good joint work is mostly preparation, so that is 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 few frames, or a day or more for a whole house. Somewhere as small as Easton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Advice
What window mastic looks like in Easton
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.
Managing a site like Peter Symonds College? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
