External mastic in Chartham Hatch
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on render & cladding joints, concrete & block and copings & trims, and common reasons people get in touch are failed seals between different materials and brick movement joints where the sealant has split.
External sealant needs dry, clean surfaces, so work around Chartham Hatch is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Walls and rooflines in Chartham Hatch
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as The Canterbury Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

A few problems are outside what sealant work can do:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that’s more than a sealant joint can take
- Render that is blown, hollow or coming away

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building.

Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

When to call us in Chartham Hatch
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
It’s worth asking for a quote if you see:
- Joints pointed up with cement by mistake
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Weathered mastic that no longer stretches
Letting a property close to Chartham station? Then split movement joints are easy to miss on a rental until damp shows inside.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Keep water from gutters off the wall
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
