Window & door mastic in Ashurst, Kent
Window mastic for Ashurst and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
Common problems we fix in Ashurst
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
People normally contact us when they notice something like this:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
If you let a flat or house near Ashurst Kent station, renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic for homes and businesses in Ashurst
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have gaps between the frame and the inside reveal and water coming in at the bottom corners of a door, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ashurst is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Ashurst as everywhere else we work.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on how much there is to do. For a village or hamlet like Ashurst, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Ashurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Window mastic in Ashurst: local notes
With historic houses such as Groombridge Place (about 1.6 miles south-east) nearby, there’s older building stock in the area around Ashurst as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Martin of Tours include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
