Signs you need window mastic in Bedford Park
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
These are the problems we are asked about most:
- Water coming in at the bottom corners of a door
- Mastic that’s falling out in pieces
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
Homes close to St Peter's include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle window mastic in Bedford Park
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We’re often asked to deal with damp patches on the reveal after heavy rain and a bead that doesn’t match the frame, across aluminium frames, timber windows & doors and composite doors.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
All of our work is guaranteed for twelve months, in Bedford Park and everywhere else we cover.

What happens on the day
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. For a job in Bedford Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

What else we do in Bedford Park
How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we can’t put right
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Faulty window hardware
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Questions from Bedford Park
Is Bedford Park in your area for window mastic?
Yes. Our work covers London and the South East, and Bedford Park is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can you help a landlord with a rental near South Acton station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Frames and glazing around Bedford Park
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. Historic houses like Hogarth's House (about 0.9 miles south) are a reminder that the area around Bedford Park 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’s traditional sand mastic.
If you let a flat or house near South Acton station, renewing tired window mastic between tenants heads off draught and damp complaints. As a London address, Bedford Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Why act early in Bedford Park
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. 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 you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
