How we handle external mastic in Leavenheath
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We are often asked to deal with joints pointed up with cement by mistake and movement joints with cracked, split or missing sealant, across copings & trims, brickwork movement joints and concrete & block.
Somewhere as small as Leavenheath, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes as standard.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Honest limits
To be straight with you, some problems need a different trade:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Brickwork movement joints

- Copings & trims
- Joints between brick and frames
Why act early in Leavenheath
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Leavenheath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Aftercare tips
Looking after new joints is easy:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
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. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The number and length of the joints
- Working hours on commercial sites
- Access and height
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. In a small place like Leavenheath, 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.
Before we arrive
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
