How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Window mastic for homes and businesses in Enfield Lock
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Typical jobs include sealant in the wrong colour for the frame and black, perished sealant on frames, across window sills, composite doors and patio & French doors.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Enfield Lock.

Why it’s worth doing now in Enfield Lock
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Enfield Lock, the repair is bigger than a sealant job.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
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.
The process
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes most of a day for a typical house, less for a few frames from start to finish. In a London area like Enfield Lock, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Advice
What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Windows and doors in Enfield Lock
Historic houses like Forty Hall (about 1.8 miles west) are a reminder that the area around Enfield Lock 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 is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Ss Peter and Paul Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Enfield Lock 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 Lock is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
