How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning for a couple of windows and a door. In Burlington Estate, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by checking each window and door with you.
- 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.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

Window mastic in Burlington Estate, done properly
Around Burlington Estate we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include hard, cracked sealant around windows and black, perished sealant on frames, on uPVC windows, composite doors and aluminium frames.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Quotes for window mastic in Burlington Estate
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- Any mould that needs treating
- Any working-time requirements on site
- How easy the joints are to reach
Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- How we’d reach the joints
- Whether it has been sealed before
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Why act early in Burlington Estate
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. In a flat in Burlington Estate, 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.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
Why us?
- Full insurance on every job
- An ARBOMaster approved applicator
- Neat joints and a tidy finish
- We never seal over old sealant

Burlington Estate questions
Can parking be tricky for a visit in Burlington Estate?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you cover Burlington Estate for window mastic?
Yes, Burlington Estate is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Are you insured?
Yes, we’re fully insured.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Surface by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
When to call us in Burlington Estate
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
People usually contact us after spotting something like this:
- Cracked internal joints between frame and plaster
- A bead that does not match the frame
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
Letting a property close to Bond Street station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Frames and glazing around Burlington Estate
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. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep timber frames painted
- Clean frames with a soft cloth and soapy water
- Walk round the house once a year and look at the joints
- Don’t use solvent cleaners on the joint
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
