External mastic in Shillinglee, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. If you have plants rooting in failed movement joints and joints where the bead has come unstuck, we can help.
Older homes in small places like Shillinglee may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Big or small, it’s backed by our one-year guarantee in Shillinglee and across Surrey.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Outside joints around Shillinglee
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.
In and around Shillinglee, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What we cannot put right
In fairness, there are a few things sealant will not fix:
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
- Render that’s blown, hollow or coming away

Shillinglee questions
I let a flat near Witley station. Can you help?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Shillinglee for external mastic?
Yes. Our work covers London and the South East, and Shillinglee is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
What information do you need?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Signs you need external mastic in Shillinglee
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
The most common problems we see are:
- Rain getting behind render or cladding at a joint
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
Rented homes near Witley station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- Are they insured?
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint

Why it’s worth doing now in Shillinglee
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. Around Shillinglee, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What you get with us
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
- We leave the area clean and tidy
- Experience in homes, commercial sites and hotels

What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. In a small place like Shillinglee, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Move anything stored near the joints
