Window & door mastic in Walthamstow Village, Greater London
Window and door frames in Walthamstow Village need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Window mastic in Walthamstow Village, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. If you’re dealing with draughty joints inside around the window and damp patches on the reveal after heavy rain, we can help.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

- Any old sealant cut out fully, not covered over

What else we do in Walthamstow Village
How we quote for window mastic
There’s no set price list. What we look at:
- Whether there’s mould to deal with
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If someone has resealed it before
- A few pictures by email, if you can
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
Honest limits
Before you book, it’s worth knowing the limits:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Composite doors
- Aluminium frames
- Patio & French doors
- Window sills
- uPVC windows
- Timber windows & doors
Different surfaces, different methods
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 check before we reseal.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We’ll tell you if that is what we find.
Your questions about window mastic in Walthamstow Village
Do you cover Walthamstow Village for window mastic?

Can parking be tricky for a visit in Walthamstow Village?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.

Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Window mastic in Walthamstow Village: local notes
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. 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 how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
