Advice
Window mastic for homes and businesses in Royal Tunbridge Wells
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with mastic that has split away from the wall and old mastic that has gone black or come away, on timber windows & doors, patio & French doors and composite doors.
Plenty of homes in a town like Royal Tunbridge Wells have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What window mastic looks like in Royal Tunbridge Wells
London and the South East are among the drier parts 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 Groombridge Place (about 3.6 miles west) nearby, there’s older building stock in the area around Royal Tunbridge Wells as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St Barnabas CofE VA Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Parish Church of St Barnabas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Do you need window mastic in Royal Tunbridge Wells?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
If you let a flat or house near Tunbridge Wells station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Your questions about window mastic in Royal Tunbridge Wells
Is Royal Tunbridge Wells in your area for window mastic?
Yes, Royal Tunbridge Wells is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Tunbridge Wells station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
