Tooting Window Mastic
Window and door frames in Tooting need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
Window mastic in Tooting
Homes in Tooting have every kind of window: 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. If you are dealing with gaps left after new windows were fitted and mastic that has split away from the wall, we can put it right, whatever the surface.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

How we quote for window mastic
The quote reflects the job in front of us. We take into account:
- Mould in or behind the old joints
- The type of sealant required
- Whether the work is at height
- The size of the job
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- A few photos by email, if you can
- Whether it has been sealed before
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.

For anyone letting property in or around Tooting, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Tooting, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on how much there is to do. In Tooting, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Yes, in most cases. Mention the frame colour when you ask for a quote and we will use the nearest match.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
What window mastic looks like in Tooting
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. 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.
Tooting is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you let a flat or house near Tooting station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to St Augustine include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
