Your questions about window mastic in Newington Butts
Is parking an issue for window mastic in Newington Butts?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Elephant & Castle station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Window mastic in Newington Butts
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. If the draught is through the window seals instead, we will tell you. If you have damp patches on the reveal after heavy rain and draughts coming in around windows and doors, we can help.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Newington Butts is something to talk through when you book.

Frames and glazing around Newington Butts
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Benjamin Franklin House (about 1.4 miles north-west) nearby, there’s older building stock in the area around Newington Butts as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Metropolitan Tabernacle, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Elephant & Castle station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Honest limits
In fairness, some problems need a different trade:
- Draughts through the window seals rather than the frame
- A sash or casement that won’t close properly
- Damp coming through the wall itself rather than the frame joint
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
- Window sills
- Aluminium frames

Your quote is based on your job. We take into account:

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business

- What’s wrong with the joints now
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or drop us an email.
Do you need window mastic in Newington Butts?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
The most common problems we see are:
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Cracked sealant at the sill ends
As a London address, Newington Butts can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How it 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 and we leave things clean and tidy. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Newington Butts. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
