How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Whether there’s mould to deal with
- Whether the work is at height
- The type of sealant required
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- The rough size of the job
- A few pictures by email, if you can
- What’s wrong with the joints now
- Where the property is
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.
External mastic in Pilgrims Hatch, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on façade panels, copings & trims and render & cladding joints, and common reasons people get in touch are sealant pulling away from one side of the joint and old sealant gone brittle and cracked.
Houses in smaller places like Pilgrims Hatch can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are normally the first to go.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why act early in Pilgrims Hatch
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. In a smaller place like Pilgrims Hatch, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
What you get with us
- Homes, businesses and hotels
- White, clear, grey or another colour, product permitting
- Trusted Arbo and Everbuild sealants
- Tidy, careful work
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Parking around Pilgrims Hatch is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Pilgrims Hatch: your questions answered
Can you do external mastic in Pilgrims Hatch?
Yes, Pilgrims Hatch is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is Pilgrims Hatch within the area you cover?
Yes. Pilgrims Hatch is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Different surfaces, different methods
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.

Aftercare tips
After the cure time, these simple habits help:
- Deal with leaking gutters that soak the joints below
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
- Do not let climbing plants root in the sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Walls and rooflines in Pilgrims Hatch
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Ingatestone Hall (about 4.6 miles north-east) are a reminder that the area around Pilgrims Hatch 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.
If you look after a building such as Larchwood Primary School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Brentwood station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Saint George's church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
