About our window mastic in Detling
Homes in Detling have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on timber windows & doors, aluminium frames and patio & French doors, and people most often call us about whistling draughts around closed windows and old mastic that has gone black or come away.
In a village or hamlet like Detling, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
- Don’t paint over the silicone
- Look round the frames every year or so
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
Your questions about window mastic in Detling
Will you come out to Detling?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Detling in your area for window mastic?
Yes. Our work covers London and the South East, and Detling is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Detling.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
How long does it take to reseal the windows on a house?
Allow a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. For a village or hamlet like Detling, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

Advice
What window mastic looks like in Detling
Historic houses like Stoneacre (about 3 miles south) are a reminder that the area around Detling has older buildings as well as new. 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Valley Park School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Martin of Tours Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When to call us in Detling
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. When that sealant fails, water gets into the wall or under the frame.
People normally contact us after spotting something like this:
- Cracked or shrunken mastic around the frame
- A bead that does not match the frame
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
Rented homes near Bearsted station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include
- Who does the work, and how experienced they are
- When the joint can take water or movement
- What happens if the job turns out different
- Whether all the old sealant comes out first
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Detling, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
