Window & door mastic in Rush Green, Greater London
Our applicators work in Rush Green on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
Window mastic in Rush Green
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Common call-outs are for sealant in the wrong colour for the frame and mastic that’s falling out in pieces, across patio & French doors, composite doors and aluminium frames.
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.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

How we quote for window mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- The amount of work
- Whether the work is at height
- Whether there’s mould to deal with
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is
- Any access issues, like height or stairs
- The address or postcode of the job
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job.
When to call us in Rush Green
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
People generally contact us after spotting something like this:
- Leaking joints at the ends of sills
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
Managing a site like Rush Green Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Landlord and commercial work in Rush Green
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

Window mastic in Rush Green: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Hare Hall (about 2.1 miles north-east) are a reminder that the area around Rush 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.
Rush Green 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 Augustine of Canterbury Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames do not stay wet inside
- Clear any debris from frame drain holes
Silicone cannot usually be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
