External mastic in Totford
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for moss and dirt in joints with no sealant left and weathered mastic that no longer stretches, on render & cladding joints, façade panels and brickwork movement joints.
Older homes in small places like Totford may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Totford: your questions answered
Do you cover Totford for external mastic?
Yes. Our work covers London and the South East, and Totford is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you cover smaller places like Totford?
Yes. Totford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
How do I get a quote for external mastic in Totford?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.

Why act early in Totford
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a small place like Totford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Landlords, agents and businesses in Totford
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
How the job changes by surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Common problems we fix in Totford
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
For landlords with property near Micheldever station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Totford buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St John the Evangelist include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens on the day
At the end, we look at the finished work together. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. In a small place like Totford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
