External & façade joints in Nonington, Kent
Professional external mastic in and around Nonington, with every bit of old sealant taken out first.
- Old sealant gone brittle and cracked
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, 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.
How we handle external mastic in Nonington
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. Common call-outs are for cracked joints where brick meets render or frames and weeds or debris growing in open joints, on copings & trims, concrete & block and façade panels.
Somewhere as small as Nonington, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Nonington, 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.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

What we’re called out for in Nonington
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
It’s worth asking for a quote if you see:
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
If you let a flat or house near Aylesham station, outside joints that have cracked can let damp into a rental, so check them between lets.

What external mastic looks like in Nonington
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodnestone Park (about 1.4 miles north) are a reminder that the area around Nonington has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Nonington Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
- Do not let climbing plants root in the sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

Where do you work from?

How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll say how long yours will take.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
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. Our work comes with a 12-month guarantee.
Why act early in Nonington
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Nonington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
