Window mastic for homes and businesses in Bucks Green
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Common call-outs are for mastic that has split away from the wall and gaps between the frame and the inside reveal, across patio & French doors, window sills and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in Bucks Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with our one-year guarantee, wherever you are in West Sussex.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Faulty window hardware
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

Signs you need window mastic in Bucks Green
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.
Keep an eye out for any of the following:
- Leaking joints at the ends of sills
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
Schools such as Pennthorpe School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
So the new joints stay in good condition:
- Do not use solvent cleaners on the joint
- Do not aim a pressure washer at the joints
- Make sure the drainage slots aren’t blocked
- Use gentle cleaners on frames and sealant
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What affects the cost of window mastic
You will get a clear quote before work begins. It takes into account:
- Any mould that needs treating
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
When you contact us, these details help:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Bucks Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky

Bucks Green homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Christs Hospital station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to St John the Baptist include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about window mastic in Bucks Green
Is Bucks Green in your area for window mastic?

Do you cover smaller places like Bucks Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I paint over the new sealant?
Most silicone can’t be painted. Let us know beforehand, and we’ll use a paintable product where it suits.

Why act early in Bucks Green
Failed mastic is not 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. Where a wall is exposed, as many are in small places like Bucks Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
