Window mastic in Malden Rushett, done properly
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you’re dealing with a bead that doesn’t match the frame and draughty joints inside around the window, we can put it right.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
Whatever the size of the job, it’s backed by our one-year guarantee.

Windows and doors in Malden Rushett
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. Historic houses like Fitznells Manor (about 3.1 miles east) are a reminder that the area around Malden Rushett has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Chessington South station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Chessington Community College, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Malden Rushett
Do you work for landlords with property near Chessington South station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Can parking be tricky for a visit in Malden Rushett?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Where are you based?
We work from Crawley. We cover Malden Rushett and the rest of Greater London.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How long will my window job take?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
What affects the cost of window mastic
We do not publish a price list. What we look at:
- Mould in or behind the old joints
- How easy the joints are to reach
- How many areas need sealing
- The old material and how stubborn it is
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 play a part.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- The type of property
- Where the property is
- The rough size of the job
We quote each job on its own. Simply ring 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.
Common problems we fix in Malden Rushett
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Keep an eye out for any of the following:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
Historic houses such as Fitznells Manor, about 3.1 miles east, show how far back building around Malden Rushett goes, and older homes nearby need a sealant that suits their walls.
What your quote should include
- How long the guarantee is
- Who does the work, and how experienced they are
- Which colour the sealant will be
- What product goes in the joint
Surface by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Landlords, agents and businesses in Malden Rushett
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Landlords and agents in Malden Rushett can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Why act early in Malden Rushett
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Malden Rushett.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Why book with us
- One-year guarantee on every job
- White, clear, grey or another colour, product permitting
- We never seal over old sealant
- 20+ years of sealant experience

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Paint up to the joint, not over it
- Clear any debris from frame drain holes
Most silicone sealants will not take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. In Malden Rushett, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
