Window Mastic in Eden Park
Mastic around window and door frames, sills and patio doors for Eden Park, backed by a one-year guarantee. Ask us for a quote.
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
Different surfaces, different methods
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
Window mastic for homes and businesses in Eden Park
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you have cracked sealant at the sill ends and sealant in the wrong colour for the frame, we can put it right, on timber windows & doors, composite doors and uPVC windows alike.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
Each job carries a 12-month guarantee, large or small.

Eden Park: your questions answered
Can parking be tricky for a visit in Eden Park?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you work for landlords with property near Eden Park station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
Do you come to Eden Park?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Eden Park.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Window mastic in Eden Park: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
As a London address, Eden Park can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St John's Eden Park, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you need window mastic in Eden Park?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
If you look after a building such as Langley Park School for Boys, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- What guarantee comes with the work
- Whether you can choose the colour
- When the joint can take water or movement
- Whether VAT is included
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Composite doors
- uPVC windows
- Patio & French doors
- Timber windows & doors

Landlords, agents and businesses in Eden Park
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- The old material and how stubborn it is
- Any mould that needs treating
- How easy the joints are to reach
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Helping us quote
When you contact us, these details help:
- Photos by email, if that is easy
- The type of property
- Any access issues, like height or stairs
- Where the job is, and your postcode

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. 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.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. For a job in Eden Park, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
