How we handle window mastic in Hurst Green
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 deep gaps get backing rod first. The sealant then grips the two sides it should. We work on aluminium frames, uPVC windows and timber windows & doors, and common reasons people get in touch are damp patches on the reveal after heavy rain and mastic that’s falling out in pieces.
Around Hurst Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What happens on the day
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes anything from an hour or two to a full day, depending on how many frames there are, and we tell you how long to leave it before we go. Somewhere like Hurst Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

What sealant work can’t fix

- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint

Do you need window mastic in Hurst Green?
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.
If you can see any of these, it’s time to have the joints looked at:
- Rushed sealant from a window installation
- Cold air getting in at the frame edge
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Hurst Green Infant School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Whether the sealant suits the joint
- How much experience the applicator has
- Which colour the sealant will be
- How the joint is cleaned and prepared
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Frames and glazing around Hurst Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Titsey Place (about 2.3 miles north) are a reminder that the area around Hurst Green 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.
Homes close to St Agatha's Hall include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Hurst Green station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
