About our window mastic in Elephant and Castle
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with leaking joints at the ends of sills and mastic that has split away from the wall, we can help, whatever the surface.
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, which is when draughts and damp patches appear in homes in Elephant and Castle.
There’s a 12-month guarantee on every job, large or small.

Common questions in Elephant and Castle
Is Elephant and Castle in your area for window mastic?
Yes, Elephant and Castle is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Elephant & Castle station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A failed sealed unit that has misted up
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Elephant and Castle. It helps if you can point us to a visitor permit or a bay close to the door.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Advice
Quotes for window mastic in Elephant and Castle
Call for a quick quote. What matters most is:
- The number and length of the joints
- The type of sealant required
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
- Do not paint over the silicone
- Clear any debris from frame drain holes
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Window mastic in Elephant and Castle: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.

Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
