Is Denton within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
Do you hold any approvals?

How long should I leave it?

Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
External mastic in Denton
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on brickwork movement joints, façade panels and render & cladding joints, and common reasons people get in touch are damp patches traced to an open external joint and movement joints filled with mortar instead of sealant.
External sealant needs dry, clean surfaces, so work around Denton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
- Make sure movement joints are not pointed over
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
Should I try it myself first?
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, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Denton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

What external mastic looks like in Denton
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Acrise Place (about 3.4 miles south-west) are a reminder that the area around Denton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Shepherds Well station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Common problems we fix in Denton
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
The most common problems we see are:
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
If you live in an older home near Church of St Mary Magdalene, older walls, gutters and the joints where extensions meet them need a flexible sealant.
