Freezywater buildings and the weather
With historic houses such as Forty Hall (about 1.7 miles west) nearby, there’s older building stock in the area around Freezywater as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Enfield Lock station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Ss Peter and Paul Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Your questions about external mastic in Freezywater
Do you work for landlords with property near Enfield Lock station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Freezywater?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need external mastic in Freezywater
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
These are the problems we are asked about most:
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Joints with sealant missing in places
Schools such as Keys Meadow Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Why it’s worth doing now in Freezywater
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Freezywater, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

How to look after the new joints
Aftercare is simple:
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
- Point out the joints to other trades
- Wash walls gently around the sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
