Surface by surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Window mastic in Albany Park
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you’re dealing with black, perished sealant on frames and rushed sealant from a window installation, we can put it right, on patio & French doors, window sills and timber windows & doors alike.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Albany Park.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Signs you need window mastic in Albany Park
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us include:
- A bead that doesn’t match the frame
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
In the older streets around St Lawrence church, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before you book

Windows and doors in Albany Park
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Historic houses like Danson House (about 2.2 miles north) are a reminder that the area around Albany Park has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Albany Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as Birkbeck Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Albany Park
Can you do window mastic in Albany Park?
Yes. Our work covers London and the South East, and Albany Park is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Sidcup station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long will my window job take?
Allow a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
How much does window mastic cost in Albany Park?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and tell us what needs doing and where.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What we do, step by step
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 most of a day for a typical house, less for a few frames. In Albany Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
Ask for a quote
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.

How we quote for window mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- How easy the joints are to reach
- The number of rooms or windows
- Working hours on commercial sites
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
What we need to know
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- If someone has resealed it before
We do not publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
