Window & door mastic in Bicknor, Kent
Problem with your window and door frames in Bicknor? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
Window mastic in Bicknor, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have gaps where the sill meets the wall and rain getting in at the frame or under the sill, we can put it right, whatever the surface.
Homes in small places like Bicknor often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job comes with our 12-month guarantee.

What window mastic looks like in Bicknor
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. With historic houses such as Leeds Castle (about 3.7 miles south-west) nearby, there’s older building stock in the area around Bicknor as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St James, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
So the new joints stay in good condition:
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Quotes for window mastic in Bicknor
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- Access and height
- Any working-time requirements on site
- Which sealant suits the joint
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Your questions about window mastic in Bicknor
Will you come out to Bicknor?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Hollingbourne station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work on first-floor windows?
Generally, yes. We plan safe access before the job.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you guarantee window mastic?
Yes. Our one-year guarantee covers every job, inside or out.
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. We remove it all first.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Do you need window mastic in Bicknor?
Water runs down the glass onto the sill, 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.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
For landlords with property near Hollingbourne station, renewing tired window mastic between tenants heads off draught and damp complaints.

- The length of the guarantee
- What product goes in the joint
- What the quote includes, VAT included or not
When it is not the sealant
It helps to know what we cannot do too:
- Condensation trapped between the panes
- Broken hinges, locks or handles
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Composite doors
- uPVC windows
- Patio & French doors
- Window sills
- Aluminium frames
- Timber windows & doors
How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a few frames, or a day or more for a whole house. In a small place like Bicknor, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
