What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Bredhurst, 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.
- Where the gap is deep, backing rod goes in first.
- 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.
How to prepare
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Window mastic in Bredhurst
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on patio & French doors, timber windows & doors and aluminium frames, and the jobs we see most are draughts coming in around windows and doors and sealant in the wrong colour for the frame.
Around Bredhurst, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What affects the cost of window mastic
You’ll get a clear quote before we start. It’s based on:
- The number and length of the joints
- Any mould that needs treating
- Access and height
- How many areas need sealing
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.
Window mastic in Bredhurst: local notes
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. With historic houses such as Restoration House (about 5 miles north-west) nearby, there’s older building stock in the area around Bredhurst 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.
For site and facilities teams at buildings such as Deanwood Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Signs you need window mastic in Bredhurst
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Keep an eye out for these signs:
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
If you let a flat or house near Rainham (Kent) station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.

Do you cover smaller places like Bredhurst?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How do I get a quote for window mastic in Bredhurst?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
