Window & door mastic in Ebbsfleet, Kent
Window mastic for Ebbsfleet, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
- Old mastic that has gone black or come away
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep paint and stain on wooden frames in good order
- Ventilate rooms so frames don’t stay wet inside
- Avoid harsh chemicals near the mastic
- Make sure the drainage slots are not blocked
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
About our window mastic in Ebbsfleet
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have mastic that’s falling out in pieces and draughty joints inside around the window, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Ebbsfleet is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Frames and glazing around Ebbsfleet
Ebbsfleet is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Thanet Parkway station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Questions from Ebbsfleet
Can you help a landlord with a rental near Thanet Parkway station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is window mastic in a coastal place like Ebbsfleet any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Can you get sealant to suit coloured frames?
Usually, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Where do you work from?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Window sills
- Aluminium frames
- Patio & French doors
- Timber windows & doors
- Composite doors
- uPVC windows
What we’re called out for in Ebbsfleet
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Signs it’s time to call us include:
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
Quex Park, about 3.8 miles north, is one of the historic houses in the wider area around Ebbsfleet, and older homes nearby need a sealant that suits their walls.
What your quote should include
- How much experience the applicator has
- How long the guarantee is
- What happens if the job turns out different
- How the surfaces are prepared before sealing
What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.

What else we do in Ebbsfleet
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Older cottages and farmhouses around Ebbsfleet can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- White, clear, grey or another colour, product permitting
- More than 20 years in sealant work
- Any old sealant cut out fully, not covered over
- Fully insured

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. For a village or hamlet like Ebbsfleet, 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on
