FAQs for Farthingloe
Is external mastic in a coastal place like Farthingloe any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
External mastic for homes and businesses in Farthingloe
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. If you have panel joints letting water in and gaps where render, brick and frames meet, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Farthingloe is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee.

Signs you need external mastic in Farthingloe
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Common reasons people contact us are:
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
Managing a site like Aycliffe Community Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Farthingloe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Walls and rooflines in Farthingloe
Farthingloe is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
For an older house near a landmark such as Aycliffe Church Centre, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Dover Priory station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Where we work in Farthingloe
- Brickwork movement joints
- Concrete & block
- Façade panels
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. In a small place like Farthingloe, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
