Window mastic in Abbey Wood, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on patio & French doors, composite doors and window sills, and the jobs we see most are draughty joints inside around the window and cracked or shrunken mastic around the frame.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Abbey Wood.
All our work comes with our one-year guarantee.

Signs you need window mastic in Abbey Wood
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- Cold air getting in at the frame edge
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
Homes close to Saint Michael and All Angels include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Why act early in Abbey Wood
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Abbey Wood.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
Why us?
- 20+ years of sealant experience
- Experience in homes, commercial sites and hotels
- Neat joints and a tidy finish
- Sanitary silicone with an anti-fungal additive in wet areas

Frames and glazing around Abbey Wood
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Danson House (about 2.1 miles south) are a reminder that the area around Abbey Wood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Alexander McLeod Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. As a London address, Abbey Wood can be tricky for parking: let us know about parking bays, permits or a driveway.

What’s near Abbey Wood
Locally, jobs take us to homes and businesses close to St Paul's Academy, Abbey Wood Park and The Plume Of Feathers Public House and the streets around them.

Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall and tooled smooth.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames don’t stay wet inside
- Keep solvents and bleach off the sealant
Silicone can’t normally be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The product the joint needs
- How many rooms, windows or areas are involved
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 the work is at height. Your quote takes all of that into account.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. In Abbey Wood, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
