External mastic in Selsted, done properly
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. We work on copings & trims, façade panels and render & cladding joints, and the jobs we see most are sealant that has lost its bond to the brick or render and plants rooting in failed movement joints.
External sealant needs dry, clean surfaces, so work around Selsted is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How the job changes by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
When to call us in Selsted
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
If you let a flat or house near Shepherds Well station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- How long the guarantee is
- Is VAT in the price?
- Who turns up on the day
- When the joint can take water or movement
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. In a small place like Selsted, access is usually the main thing to plan. 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.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

What affects the quote in Selsted
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- How many areas need sealing
- The number and length of the joints
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Roughly how big the job is
- Photos by email, if that is easy
- What’s wrong with the joints now
- Where the job is, and your postcode
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
Why it’s worth doing now in Selsted
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Selsted, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Should I try it myself first?
