Outside joints around Strood
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. Historic houses like Temple Manor (about 0.5 miles south-east) are a reminder that the area around Strood has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Strood station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Elaine Primary School, larger buildings have long runs of movement joint that eventually need resealing.

External mastic in Strood
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Common call-outs are for movement joints with cracked, split or missing sealant and old sealant gone brittle and cracked, across concrete & block, copings & trims and brickwork movement joints.
Extensions are a common sight on houses around Strood, and the joint where new wall meets old is a classic place for water to get in. Getting the joint depth right matters as much as the sealant itself.

What we’re called out for in Strood
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Damp patches traced to an open external joint
- Panel joints letting water in
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
Homes close to St Francis' Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What the cure time is
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- What happens if the job turns out different
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to several days, depending on the building. In Strood, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any tricky access
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Leave it or put it right?
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, rather than the wall around it. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Strood they get worse with every use. Now is the easy time to put it right.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Your questions about external mastic in Strood
Do you cover Strood for external mastic?

Do you work for landlords with property near Strood station?

What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Have failed joints looked at early
- Point out the joints to other trades
- Keep water from gutters off the wall
- Make sure movement joints are not pointed over
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
When it is not the sealant
A few problems are outside what sealant work can do:
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
