About our window mastic in Enfield Highway
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with damp patches on the reveal after heavy rain and mastic that has split away from the wall, we can put it right, whatever the surface.
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, and access in Enfield Highway is something to talk through when you book.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of frames, longer for a whole house from start to finish. In Enfield Highway, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Mention any parking rules near the property

Keeping the joints in good condition
So the new joints stay in good condition:
- Check the mastic once a year
- Don’t use solvent cleaners on the joint
- Keep jet washers away from the mastic
- Wipe condensation off the frames
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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.
Landlords, agents and businesses in Enfield Highway
We also work for property managers and facilities teams. Several sites can go on one quote.
Letting agents and landlords in Enfield Highway can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window mastic in Enfield Highway: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Brimsdown 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. Enfield Highway is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like Enfield Heights Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in Enfield Highway
We quote each job individually. These are the things that affect it:
- How easy the joints are to reach
- Working hours on commercial sites
- How many areas need sealing
- How much there is to do
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The rough size of the job
- Whether it has been sealed before
- The type of property
- The problem you’ve noticed
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and pictures are welcome.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- A sash or casement that will not close properly
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
What we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
- Timber windows & doors

Enfield Highway: your questions answered
Is Enfield Highway in your area for window mastic?
Yes, Enfield Highway is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Is parking an issue for window mastic in Enfield Highway?
Parking in Enfield Highway, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can resealing stop a draught around my window?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee, and we are ARBOMaster approved applicators.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before work begins.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
