External Mastic in Buttsbury
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Buttsbury and across Essex. Fully insured, ARBOMaster approved and guaranteed for a year.

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. In a small place like Buttsbury, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- Mention any tricky access

External mastic for homes and businesses in Buttsbury
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We’re often asked to deal with joints pointed up with cement by mistake and plants rooting in failed movement joints, on concrete & block, copings & trims and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Buttsbury is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, you get the same one-year guarantee.

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
What affects the quote in Buttsbury
Call for a quick quote. What matters most is:
- Access and height
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Where the job is, and your postcode
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Why it’s worth doing now in Buttsbury
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Buttsbury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot 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, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Other services in Buttsbury
Walls and rooflines in Buttsbury
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. With historic houses such as Ingatestone Hall (about 0.8 miles north) nearby, there’s older building stock in the area around Buttsbury as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Ingatestone station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Brightside Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Giles include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Honest limits
New sealant can’t fix everything, and we’ll tell you before any work starts. It will not solve:
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
