External mastic for homes and businesses in Oak Corner
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we do not skip that step. We work on joints between brick and frames, brickwork movement joints and concrete & block, and common reasons people get in touch are joints with sealant missing in places and rigid filler in a joint that should flex.
In a village or hamlet like Oak Corner, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Landlord and commercial work in Oak Corner
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Oak Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Mention any tricky access

What affects the quote in Oak Corner
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The product the joint needs
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

- Where the property is
- If someone has resealed it before
- The problem you’ve noticed
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job, and photos are welcome.
Oak Corner questions
Do you work for landlords with property near Thorpe-Le-Soken station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Does the coastal weather in Oak Corner affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
When to call us in Oak Corner
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
For landlords with property near Thorpe-Le-Soken station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- Is VAT in the price?
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Oak Corner, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

Oak Corner buildings and the weather
Oak Corner is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Parish Church of St Leonard include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
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.
