About our window mastic in Ladywell
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have black, perished sealant on frames and leaking joints at the ends of sills, we can help, whatever the surface.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
There’s a 12-month guarantee on every job.

- Mastic that has split away from the wall
- Water coming in at the bottom corners of a door

FAQs for Ladywell
Is parking an issue for window mastic in Ladywell?
Parking in Ladywell, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Ladywell station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The type of sealant required
- Whether there’s mould to deal with
- The number of rooms or windows
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Why it’s worth doing now in Ladywell
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why book with us
- We leave the area clean and tidy

Ladywell homes and the weather
Historic houses like Queen's House (about 2 miles north) are a reminder that the area around Ladywell has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
In the older streets around Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Ladywell station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Surfaces we seal
- uPVC windows
- Window sills
- Timber windows & doors
- Composite doors
- Patio & French doors
- Aluminium frames
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Do not paint over the silicone
- Keep paint and stain on wooden frames in good order
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

Advice
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
