How we handle window mastic in Stuppington
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on uPVC windows, timber windows & doors and window sills, and people most often call us about old mastic that has gone black or come away and gaps where the sill meets the wall.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stuppington is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by a one-year guarantee, wherever you are in Kent.

Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a small place like Stuppington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Colour agreed with you before work begins
- Neat joints and a tidy finish
- Old sealant always removed completely
- Anti-fungal silicone where joints get wet

What window mastic looks like in Stuppington
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Simon Langton Grammar School for Boys? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Canterbury East station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Your questions about window mastic in Stuppington
I let a flat near Canterbury East station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Stuppington?
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.
Do you have insurance?
Yes, we’re fully insured.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Clean frames with a soft cloth and soapy water
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
- Do not paint over the silicone
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
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.
What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- Which sealant suits the joint
- The number of rooms or windows
- Access and height
- Whether old sealant or filler has to be cut out
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

- uPVC windows
