Window mastic for homes and businesses in Beggar's Bush
Around Beggar's Bush we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have draughts coming in around windows and doors and black, perished sealant on frames, we can help.
Around Beggar's Bush, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep jet washers away from the mastic
- Wash the frames with mild soapy water
- Keep timber frames painted
- Air rooms to keep condensation down around windows
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What window mastic looks like in Beggar's Bush
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as St Leonard's Hill (about 4.3 miles north) nearby, there’s older building stock in the area around Beggar's Bush as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Holy Trinity CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Sunningdale station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
- Soft or decayed wood in the frame
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Why it’s worth doing now in Beggar's Bush
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Beggar's Bush, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
