Window mastic in Holloway Down, done properly
Frames and walls do not move together. 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. If you have gaps left after new windows were fitted and rain getting in at the frame or under the sill, we can help, on uPVC windows, timber windows & doors and window sills alike.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Holloway Down as anywhere.
Our work is backed for twelve months, in Holloway Down and everywhere else we cover.

Window mastic in Holloway Down: local notes
Historic houses like Sutton House (about 2.4 miles west) are a reminder that the area around Holloway Down has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
If you look after a building such as The Jenny Hammond Primary School, its window and door frames need their mastic kept sound, just like a home’s. Holloway Down is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Is parking a problem for a job in Holloway Down?
Parking in Holloway Down, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is the work guaranteed?
Yes, for 12 months. A yearly look at the joints helps them last.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you do upstairs windows?
Normally, yes. Access is planned before work begins.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Why act early in Holloway Down
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Holloway Down, the repair is bigger than a sealant job.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Landlords, agents and businesses in Holloway Down
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams in Holloway Down and across Greater London. We can quote a run of properties together, and we’re fully insured for the work.
When to call us in Holloway Down
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
The most common problems we see are:
- A bead that does not match the frame
- Black, perished sealant on frames
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
Letting a property close to Maryland station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from an hour or two to a full day, depending on how many frames there are. In a London area like Holloway Down, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Clear the area around the work

What the job involves on each surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
When something else is needed
New sealant cannot fix everything, and we will tell you before we start. It will not solve:
- Worn gaskets, brush seals or a door that has dropped
- Penetrating damp from a failed cavity tray or render
- A failed sealed unit that has misted up
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Composite doors
- Aluminium frames
- uPVC windows
- Window sills
- Patio & French doors
- Timber windows & doors
Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
