What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- The problem you’ve noticed
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
How we handle external mastic in Shalford
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. We’re often asked to deal with weeds or debris growing in open joints and gaps where render, brick and frames meet, across joints between brick and frames, brickwork movement joints and concrete & block.
Somewhere as small as Shalford, homes and farm buildings often face open ground, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

External mastic in Shalford: local notes
Historic houses like Guildford Castle (about 1.5 miles north) are a reminder that the area around Shalford has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Shalford station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Shalford Infant School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Mary the Virgin include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Your questions about external mastic in Shalford
Is Shalford within the area you cover?
Yes, Shalford is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Shalford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. We will reseal it with a flexible sealant.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
Why act early in Shalford
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Shalford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Render & cladding joints
- Façade panels
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
Aftercare tips
So the new joints stay in good condition:
- Tell anyone working on the walls about the movement joints
- Make sure movement joints aren’t pointed over
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What the job involves on each surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to several days, depending on the building. For a village or hamlet like Shalford, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
