External & façade joints in Penenden Heath, Kent
Movement joints in Penenden Heath need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Plants rooting in failed movement joints
- Water getting into walls through failed joints
- Hard, crazed mastic that has stopped moving
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
External mastic in Penenden Heath
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on render & cladding joints, concrete & block and joints between brick and frames, and people most often call us about rigid filler in a joint that should flex and water getting into walls through failed joints.
Around Penenden Heath, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

When to call us in Penenden Heath
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant
Managing a site like St Paul's Infant School? Then larger buildings have long runs of movement joint that eventually need resealing.
Before booking anyone
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- How the colour is chosen
- How much experience the applicator has
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a smaller place like Penenden Heath, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Landlords, agents and businesses in Penenden Heath
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens on the day
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. For a job in Penenden Heath, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Clear items away from the joints we are working on
- Mention any tricky access
- Tell us about any water getting in

What external mastic looks like in Penenden Heath
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 Stoneacre (about 2.9 miles south-east) are a reminder that the area around Penenden Heath 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.
Homes close to St Paul's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Maidstone East station, split movement joints are easy to miss on a rental until damp shows inside.
