Advice
Windows and doors in Herne Common
Herne Common is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Herne Bay station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Herne Church of England Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Martin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Check the mastic once a year
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Should I try it myself first?
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 doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

We will not take on work that will not last, so these are the limits:

What happens if it’s left?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Older cottages and farmhouses around Herne Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Herne Common: your questions answered
Is Herne Common within the area you cover?
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.
Is window mastic in a coastal place like Herne Common any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Different surfaces, different methods
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
