The process
At the end, we look at the finished work together. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on how much there is to do. For a village or hamlet like Petteridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

About our window mastic in Petteridge
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include sealant in the wrong colour for the frame and gaps left after new windows were fitted, on timber windows & doors, composite doors and window sills.
Somewhere as small as Petteridge, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes as standard, so you are covered after we have gone.

Honest limits
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How the job changes by surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
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 suits the frame.
Why deal with it now?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Petteridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Do you need window mastic in Petteridge?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Most people get in touch when they notice one of these:
- Whistling draughts around closed windows
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
For an older house near a landmark such as Ebenezer Church (Matfield), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Petteridge homes and the weather
With historic houses such as Scotney Castle (about 3.8 miles south) nearby, there’s older building stock in the area around Petteridge 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. 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 Brenchley and Matfield Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Paddock Wood station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Does the work come with a guarantee?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
