What happens if it’s left?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. In a flat in Luxted, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why Luxted customers choose us
- An ARBOMaster approved applicator
- Over 20 years’ experience

About our window mastic in Luxted
If you can feel air around a shut window, the gap is often at the frame. 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. We work on composite doors, timber windows & doors and patio & French doors, and common reasons people get in touch are leaking joints at the ends of sills and rushed sealant from a window installation.
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.
All our work comes with a 12-month guarantee.

Questions from Luxted
Can you do window mastic in Luxted?
Yes. Our work covers London and the South East, and Luxted is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Is parking an issue for window mastic in Luxted?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
How much does window mastic cost in Luxted?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before we start.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
When something else is needed
To be straight with you, some problems need a different trade:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- A sash or casement that won’t close properly
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- uPVC windows
- Composite doors
- Window sills
Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes most of a day for a typical house, less for a few frames. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Luxted. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Frames and glazing around Luxted
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. With historic houses such as Down House (about 0.5 miles north) nearby, there’s older building stock in the area around Luxted as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Cudham Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in.

When to call us in Luxted
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Damp patches on the reveal after heavy rain
- Cracked or shrunken mastic around the frame
- Cold air getting in at the frame edge
- White mastic on grey or black frames
For landlords with property near Chelsfield station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

- How the joint is cleaned and prepared
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
