Window & door mastic in Hawkenbury, Kent
We cover Hawkenbury for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
How we handle window mastic in Hawkenbury
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on window sills, uPVC windows and composite doors, and people most often call us about water coming in at the bottom corners of a door and mastic that’s falling out in pieces.
Many houses in smaller places like Hawkenbury have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Big or small, you get the same 12-month guarantee.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

How it works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. Parking around Hawkenbury is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Advice
Landlords, agents and businesses in Hawkenbury
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Hawkenbury, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Common problems we fix in Hawkenbury
Sills take more water than any other part of a window, 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.
These are the problems we’re asked about most:
- Gaps left after new windows were fitted
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
Managing a site like Claremont Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about window mastic in Hawkenbury
Do you cover Hawkenbury for window mastic?

Is there any odour?

Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
How much does window mastic cost in Hawkenbury?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Windows and doors in Hawkenbury
London and the South East are among 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 Groombridge Place (about 3.9 miles west) nearby, there’s older building stock in the area around Hawkenbury 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 St Peter's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Tunbridge Wells station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Aftercare tips
After the cure time, these simple habits help:
- Keep timber frames painted
- Keep paint off silicone joints
- Wipe condensation off the frames
- Check the mastic once a year
Most silicone sealants won’t take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
