Window Mastic in Bockmer End
Problem with your window and door frames in Bockmer End? We remove the old material, prepare the joints and seal them properly.
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- Rain getting in at the frame or under the sill
What happens if it’s left?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. Around Bockmer End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
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.
Why Bockmer End clients choose us
- Every job guaranteed for a year
- Neat joints and a tidy finish
- Quality sealants from Arbo and Everbuild
- We never seal over old sealant
Window mastic in Bockmer End
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on window sills, patio & French doors and composite doors, and common reasons people get in touch are gaps left after new windows were fitted and draughts coming in around windows and doors.
Mastic can only go onto a dry, clean joint, so window work in Bockmer End is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job.

Advice
Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Frames and glazing around Bockmer End
Historic houses like Harleyford Manor (about 1 mile south-east) are a reminder that the area around Bockmer End 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Danesfield School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Marlow station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we’re called out for in Bockmer End
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The problems people generally mention when they call are:
- A bead that does not match the frame
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
Homes close to Church of St Peter and St Paul include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How long the guarantee is
- How the surfaces are prepared before sealing
- What the quote includes, VAT included or not
- How long to leave it before use
Looking after it afterwards
To keep the joints looking good and working properly:
- Wipe condensation off the frames
- Paint up to the joint, not over it
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What we can’t put right
We won’t take on work that will not last, so these are the limits:
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
If in doubt, call 0345 464 0079 or email us and we will say what we think.
