External mastic in Street End, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. Common call-outs are for gaps where render, brick and frames meet and old sealant gone brittle and cracked, across concrete & block, façade panels and joints between brick and frames.
Around Street End, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Whatever the size of the job, you get the same one-year guarantee.

Outside joints around Street End
Street End is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Chichester station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Sidlesham Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What else we do in Street End
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- The number and length of the joints
- The number of rooms or windows
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- A few photos by email, if you can
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
We do not publish a price list. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or drop us an email.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Render & cladding joints
- Copings & trims
- Façade panels
- Joints between brick and frames

FAQs for Street End
Does living near the coast affect external mastic in Street End?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Chichester station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. We will confirm how long when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
For landlords and businesses
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Why it’s worth doing now in Street End
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Street End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Advice
What we’re called out for in Street End
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch after spotting one of these:
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
In the older streets around St Mary Our Lady Sidlesham, the joints between older walls, newer extensions and the roofline need a sealant that can move.
