About our window mastic in Hayes
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for sealant in the wrong colour for the frame and hard, cracked sealant around windows, across composite doors, aluminium frames and patio & French doors.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Windows and doors in Hayes
Historic houses like Bromley Palace (about 2 miles north) are a reminder that the area around Hayes 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 is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Hayes is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.

What we are called out for in Hayes
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
- Gaps where the sill meets the wall
For site and facilities teams at buildings such as Hawes Down Primary School, the mastic around its windows and doors needs looking after like any other building’s.

- Whether the sealant suits the joint
- When the joint can take water or movement

That depends on the sealant used, so please follow the time we give you.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
If you manage several properties in or around Hayes, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Broken hinges, locks or handles
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a flat in Hayes, 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.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

- Full insurance on every job

How the visit works
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 a few hours for a few frames, or a day or more for a whole house from start to finish. In Hayes, 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 how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Let us know about parking restrictions

Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t paint over the silicone
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Make sure the drainage slots are not blocked
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
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.
