What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window mastic for homes and businesses in Stowting Common
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We are often asked to deal with cracked sealant at the sill ends and cold air getting in at the frame edge, across composite doors, window sills and aluminium frames.
Around Stowting Common, 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.

Signs you need window mastic in Stowting Common
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Rushed sealant from a window installation
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
If you let a flat or house near Westenhanger station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Stowting Common: local notes
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. Historic houses like Westenhanger Castle (about 3.7 miles south) are a reminder that the area around Stowting Common has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Stowting Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Stowting Common questions
Can you do window mastic in Stowting Common?
Yes, Stowting Common is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
I let a flat near Westenhanger station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can new window sealant be painted?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you have sealant for grey or black windows?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Keeping the joints in good condition
So the new joints stay in good condition:
- Ventilate rooms so frames don’t stay wet inside
- Keep jet washers away from the mastic
- Keep paint and stain on wooden frames in good order
- Don’t paint over the silicone
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Leave it or put it right?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Stowting Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Stowting Common, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any parking rules near the property
- Mention any tricky access
