How we handle window mastic in South Alkham
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you are dealing with hard, cracked sealant around windows and draughty joints inside around the window, we can help, whatever the surface.
Homes in small places like South Alkham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, whatever its size.

When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Faulty window hardware
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render

Your questions about window mastic in South Alkham
Will you come out to South Alkham?
Yes. South Alkham 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.
Do you work for landlords with property near Kearsney station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like South Alkham, 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.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises

Frames and glazing around South Alkham
South Alkham is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Acrise Place (about 3.5 miles west) nearby, there’s older building stock in the area around South Alkham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Kearsney station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Anthony the Martyr, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Nearby places to South Alkham
Also in South Alkham
Surface by surface
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
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.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around South Alkham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
