About our window mastic in Pett Bottom
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you are dealing with gaps between the frame and the inside reveal and gaps where the sill meets the wall, we can help, on patio & French doors, aluminium frames and window sills alike.
Around Pett Bottom, 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.
You get a 12-month guarantee, the same in Pett Bottom as everywhere else we work.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Avoid harsh chemicals near the mastic
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Common problems we fix in Pett Bottom
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
Any of these means the joints need attention:
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
For landlords with property near Bekesbourne station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- What insurance they hold
- How long the guarantee is
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Pett Bottom needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What window mastic looks like in Pett Bottom
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Simon Langton Grammar School for Boys, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
