Window mastic in Ducklington
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for rushed sealant from a window installation and whistling draughts around closed windows, across timber windows & doors, window sills and composite doors.
Somewhere as small as Ducklington, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

Why deal with it now?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Around Ducklington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that won’t close properly
- Soft or decayed wood in the frame

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

What affects the quote in Ducklington
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- Access and height
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Frames and glazing around Ducklington
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Minster Lovell Hall (about 3 miles north-west) are a reminder that the area around Ducklington 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.
For an older house near a landmark such as Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Ducklington: your questions answered
Do you cover smaller places like Ducklington?
Yes. Ducklington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on window mastic in Ducklington?
All our work, in Ducklington and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you have insurance?
Yes. We’re fully insured.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
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.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Common problems we fix in Ducklington
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Look out for these signs:
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
Schools such as Ducklington Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work.

- 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.
