Window mastic in Gidea Park
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we will say so. We work on window sills, aluminium frames and uPVC windows, and the jobs we see most are leaking joints at the ends of sills and old mastic that has gone black or come away.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Gidea Park.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a flat in Gidea Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Air rooms to keep condensation down around windows
- Don’t use solvent cleaners on the joint
- Make sure the drainage slots are not blocked
- Keep paint and stain on wooden frames in good order
Silicone can’t generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Gidea Park homes and the weather
With historic houses such as Hare Hall (about 0.6 miles south-east) nearby, there’s older building stock in the area around Gidea Park as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
If you let a flat or house near Gidea Park station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Gidea Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Common problems we fix in Gidea Park
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:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Damp patches on the reveal after heavy rain
Managing a site like Royal Liberty School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include

What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are.

- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any tricky access
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
