About our window mastic in Dover
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, timber windows & doors and aluminium frames, and common reasons people get in touch are black, perished sealant on frames and whistling draughts around closed windows.
Around Dover, many houses have gained conservatories, French doors or replacement windows over time. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
Each job carries a 12-month guarantee.
Signs you need window mastic in Dover
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Black, perished sealant on frames
For an older house near a landmark such as Parish Church of St Andrew Buckland, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.

Questions from Dover
Is Dover in your area for window mastic?
Yes, Dover is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Is window mastic in a coastal place like Dover any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Are you insured?
Yes. We are fully insured for every job we do.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Frames and glazing around Dover
Dover is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Dover Priory station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Shatterlocks Infant School, its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Dover
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Dover they get worse with every use. Replacing the sealant now is the simplest fix.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes most of a day for a typical house, less for a few frames. Parking in a town like Dover is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

Landlords, agents and businesses in Dover
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate rooms so frames don’t stay wet inside
- Clear any debris from frame drain holes
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
