Window & door mastic in West End, Kent
Mastic around window and door frames, sills and patio doors for homes and businesses in West End and across Kent. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- A bead that does not match the frame
- Black, perished sealant on frames
- Untidy mastic left by window fitters
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. In a small place like West End, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Advice
Window mastic in West End, done properly
Homes in West End have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on aluminium frames, patio & French doors and composite doors, and people most often call us about cold air getting in at the frame edge and untidy mastic left by window fitters.
Around West End, 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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What affects the quote in West End
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The size of the job
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What we need to know
When you call or email, these details help:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Photos by email, if that’s easy
- Roughly how big the job is
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
Landlords, agents and businesses in West End
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Landlords and agents in West End can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Surfaces we seal

Your questions about window mastic in West End
Do you work for landlords with property near Chestfield & Swalecliffe station?
Yes, rental work is part of what we do. You can call 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 West End?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
How much does window mastic cost in West End?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Windows and doors in West End
West End is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Chestfield & Swalecliffe station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to St Peter include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Common problems we fix in West End
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Look out for these signs:
- A bead that doesn’t match the frame
- Damp patches on the reveal after heavy rain
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
Schools such as Thornden Wood Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
