Window mastic in Shortfield Common
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have cracked internal joints between frame and plaster and mastic that’s falling out in pieces, we can put it right, whatever the surface.
In a village or hamlet like Shortfield Common, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Common problems we fix in Shortfield Common
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Look out for these signs:
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
For an older house near a landmark such as Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Shortfield Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Shortfield Common questions
Is Shortfield Common within the area you cover?
Yes. Shortfield Common 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 Farnham station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can new window sealant be painted?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Shortfield Common needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Let us know about earlier repairs to the joints

Window mastic in Shortfield Common: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Farnham Castle (about 3 miles north) are a reminder that the area around Shortfield Common has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Farnham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Edgeborough School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
When it is not the sealant
In fairness, some problems need a different trade:
- A frame that has rotted at the joint
- Faulty window hardware
- Damp problems in the wall away from the window
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
