Window mastic for homes and businesses in Midgham
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on aluminium frames, uPVC windows and timber windows & doors, and common reasons people get in touch are old mastic that has gone black or come away and white mastic on grey or black frames.
Around Midgham, 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.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Frames and glazing around Midgham
With historic houses such as Shaw House (about 4.9 miles west) nearby, there’s older building stock in the area around Midgham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Matthew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Midgham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Surface by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
What affects the cost of window mastic
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The product the joint needs
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- The rough size of the job
- If someone has resealed it before
- The type of property
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Midgham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- 4.9 on Google from 180+ five-star reviews
- White, clear, grey or another colour, product permitting
- 12-month guarantee on every job
- Any old sealant cut out fully, not covered over

Do you need window mastic in Midgham?
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us include:
- Cracked sealant at the sill ends
- Draughty joints inside around the window
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
Managing a site like Bucklebury C.E. Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

The process
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a morning for a couple of windows and a door for a typical job. Somewhere as small as Midgham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Your questions about window mastic in Midgham
Do you cover Midgham for window mastic?
Yes. We work across London and the South East, and Midgham is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Is Midgham 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.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Can new window sealant be painted?
Most silicone cannot be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not paint over the silicone
- Don’t use solvent cleaners on the joint
- Clear any debris from frame drain holes
- Wipe condensation off the frames
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
