Why it’s worth doing now in Blake End
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a small place like Blake End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

External mastic in Blake End
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. Common call-outs are for failed seals between different materials and leaking joints around cladding and façade panels, on façade panels, concrete & block and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Blake End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Blake End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What external mastic looks like in Blake End
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.
Letting a property close to Braintree station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Around Blake End, as everywhere, external mastic is only as good as the preparation behind it.

What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
There’s no need for technical detail. Just tell us:
- Where the property is
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Roughly how big the job is
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Check external joints each spring
- Have failed joints looked at early
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer

What we seal
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Façade panels
- Render & cladding joints
- Joints between brick and frames
Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
