Window mastic in Notting Dale: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Sambourne House (about 1.1 miles south-east) nearby, there’s older building stock in the area around Notting Dale as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Notting Dale can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Thomas Jones Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Window mastic for homes and businesses in Notting Dale
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, window sills and composite doors, and common reasons people get in touch are hard, cracked sealant around windows and gaps between the frame and the inside reveal.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
Every job is covered by our 12-month guarantee, wherever you are in Greater London.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a morning for a couple of windows and a door, depending on the size of the job. 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 check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

FAQs for Notting Dale
Is parking a problem for a job in Notting Dale?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Shepherds Bush station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as that is a job for a joiner.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

What we’re called out for in Notting Dale
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
Keep an eye out for any of the following:
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- White mastic on grey or black frames
Rented homes near Shepherds Bush station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Whether you can choose the colour
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- The length of the guarantee

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Wash the frames with mild soapy water
- Check the mastic once a year
- Keep timber frames painted
- Keep jet washers away from the mastic
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
