How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. 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.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
Getting a quote
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.

Window mastic in Vauxhall, done properly
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on composite doors, aluminium frames and patio & French doors, and the jobs we see most are old mastic that has gone black or come away and cracked sealant at the sill ends.
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 Vauxhall is something to talk through when you book.
All our work is covered by a one-year guarantee.

Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Window mastic in Vauxhall: local notes
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 Benjamin Franklin House (about 1.2 miles north) nearby, there’s older building stock in the area around Vauxhall as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Peter's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Vauxhall Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Vauxhall is about 1 mile south-west of London, in Greater London. Across the SE11 area, we can carry out window mastic at your property. Vauxhall is one of 764 places in Greater London we cover for window mastic.
All of SE11, SW1P and SW8 is within our area for window mastic, from the main roads to the quietest streets. Local streets include Gibson Road, Langley Lane and Randall Road, and we cover them all. Vauxhall sits on or near the A3203 and A3204, which makes travel easy. Nearby, we also carry out window mastic in Lambeth (1 mile north), Kennington (1 mile south), Oval (1 mile south), Newington Butts (1 mile east) and St George's Fields (1 mile north-east). Within a short drive, we also cover Kensington (4 miles west), Shoreditch (3 miles north-east), Walthamstow (8 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles north-east) and Hampstead (5 miles north-west).

You’ll also find Old Paradise Gardens (less than half a mile north) and The Jolly Gardeners pub (less than half a mile north-east). Vauxhall has its own railway station: Vauxhall station.

When it is not the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
- Condensation trapped between the panes

What else we do in Vauxhall
Common questions in Vauxhall
Do you cover Vauxhall for window mastic?
Yes. Our work covers London and the South East, and Vauxhall is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Can you help a landlord with a rental near Vauxhall station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
What we’re called out for in Vauxhall
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Common reasons people contact us include:
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
- A bead that does not match the frame
- Black, perished sealant on frames
Letting a property close to Vauxhall station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- Is VAT in the price?
- Whether they’re fully insured
Landlords, agents and businesses in Vauxhall
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. 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.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
