Window mastic for homes and businesses in Golden Cross
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have gaps between the frame and the inside reveal and cold air getting in at the frame edge, we can put it right, on window sills, uPVC windows and aluminium frames alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Golden Cross is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Look round the frames every year or so
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the 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.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a morning for a couple of windows and a door, depending on how much there is to do. In a small place like Golden Cross, access is generally 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.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Advice
What window mastic looks like in Golden Cross
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Michelham Priory (about 2.3 miles south-east) nearby, there’s older building stock in the area around Golden Cross as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you let a flat or house near Berwick (Sussex) station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Chiddingly Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as The Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Your questions about window mastic in Golden Cross
Is Golden Cross in your area for window mastic?
Yes. Our work covers London and the South East, and Golden Cross is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you get sealant to suit coloured frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Surface by surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that’s a job for a joiner.
When something else is needed
We won’t take on work that will not last, so these are the limits:
- Damp problems in the wall away from the window
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
