Window mastic in Cannon's Green, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We work on aluminium frames, uPVC windows and patio & French doors, and the jobs we see most are hard, cracked sealant around windows and sealant in the wrong colour for the frame.
Around Cannon's Green, 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.
All of our work is guaranteed for twelve months.

What window mastic looks like in Cannon's Green
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 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. Managing a site like The Ongar Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
To keep the joints looking good and working properly:
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
FAQs for Cannon's Green
What guarantee comes with window mastic in Cannon's Green?
All our work, in Cannon's Green and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Cannon's Green?
Yes, Cannon's Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you reach windows above the ground floor?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
How long will my window job take?
A handful of frames is a short visit. We confirm the timing with your quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Surface by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Cannon's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

- Whether it’s a home or a business
There’s no standard price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
What happens on the day
The work is kept neat and contained to the joints we’re treating. The job generally takes a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. In a small place like Cannon's Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
