How we handle window mastic in Chartham Hatch
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we will say so. We work on timber windows & doors, patio & French doors and composite doors, and people most often call us about cracked sealant at the sill ends and gaps left after new windows were fitted.
Around Chartham Hatch, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Chartham Hatch
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
People normally contact us when they notice one of these:
- Gaps where the sill meets the wall
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
- Old mastic that has gone black or come away
If you let a flat or house near Chartham station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Somewhere like Chartham Hatch needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

Advice
Why it’s worth doing now in Chartham Hatch
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like Chartham Hatch, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What you get with us
- Neat joints and a tidy finish
- Anti-fungal sanitary silicone in wet areas
- We’re fully insured
- Any old sealant cut out fully, not covered over

What window mastic looks like in Chartham Hatch
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as The Canterbury Academy, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Don’t use solvent cleaners on the joint
- Check the mastic once a year
- Keep jet washers away from the mastic
- Clean frames with a soft cloth and soapy water
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
