External mastic in Hornestreet
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on joints between brick and frames, render & cladding joints and concrete & block, and the jobs we see most are rain getting behind render or cladding at a joint and movement joints with cracked, split or missing sealant.
In a village or hamlet like Hornestreet, older cottages and farm buildings often stand in the open, 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.
All our work comes with our one-year guarantee.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid pressure-washing directly into sealant joints
- Walk round the building once a year and look at the joints
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the quote in Hornestreet
There’s no set price list, because no two jobs are the same. What we look at:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Whether the work is at height
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- What’s wrong with the joints now
- The type of property
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or email us.
What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Hornestreet, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Walls and rooflines in Hornestreet
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Castle House (about 2.4 miles east) are a reminder that the area around Hornestreet has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Colchester station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Langham Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

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.
How much does external mastic cost in Hornestreet?
Size, access and the old material all affect the cost. Call for a quick quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Common problems we fix in Hornestreet
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
Historic houses such as Castle House, about 2.4 miles east, show how far back building around Hornestreet goes, and older homes nearby need a sealant that suits their walls.

Why it’s worth doing now in Hornestreet
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Hornestreet, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
