External mastic in Garlinge Green
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We’re often asked to deal with cracked joints where brick meets render or frames and sealant pulling away from one side of the joint, across façade panels, copings & trims and concrete & block.
In a village or hamlet like Garlinge Green, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, you get the same 12-month guarantee.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
Aftercare is simple:
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
- Make sure movement joints are not pointed over
- Avoid pressure-washing directly into sealant joints
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted and spoil the finish.
Once a joint cannot move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

How it works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Garlinge Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

What affects the quote in Garlinge Green
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- The old material and how stubborn it is
- The number and length of the joints
- When we can work, for business premises
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Roughly how big the job is
- A few pictures by email, if you can
- Whether it’s a home or a business
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear price.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Garlinge Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
