Facade sealing in Southwick, done properly
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. The enquiries we see most involve patch repairs that keep failing and draughts around frames and panels, on coping and flashing joints, shopfront frames and cladding panel joints. A single leaking joint is often how a building in Southwick first comes to us: we look at the rest while we’re there and tell you what we find.
For a contractor on a smaller site near Southwick, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Several jobs near Southwick can be grouped on one trip. Tell us your site hours and we will plan around them.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Share the asbestos register for older buildings
- Send any specification or drawings in advance
- Point out parking and an unloading spot
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
What sets the cost
Before we quote, we look at:
- The product specified
- Phasing around occupants
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- Approximate linear metres or a joint schedule
- Any specification or named product
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send details through our quote form.
Do you need facade sealing in Southwick?
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.
It’s worth sending us details if you spot any of the following:
- Staining on stone next to old sealant
- Draughts around frames and panels
- Gaps between rainscreen or cladding panels
- Old perimeter mastic that has dried out
Units on estates such as Grange Industrial Estate (0.5 miles south-west of Southwick) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Facade sealing in Southwick: the local picture
Southwick sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Southwick lies roughly 46 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
Extensions at sites like Southlands Hospital (1 mile west of Southwick) typically sit beside working departments, and the mastic follows strict access rules. Older buildings in the area around Southwick, such as Portslade Manor (0.8 miles north-east of Southwick), need care when sealed: the product has to suit soft or historic materials.
Southwick is about 2 miles east of Shoreham-by-Sea, in West Sussex. Businesses, contractors and managing agents in Southwick use us for work on facade joints, as part of our coverage of West Sussex. Our West Sussex coverage takes in 373 places.

Looking after the joints
For the best life from the joints:
- Note when each elevation was last resealed
- Investigate damp beside windows promptly
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

Why deal with it now?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Damp caused by condensation inside the building
- Installing or repairing glazing systems
- Render or concrete edges that have broken away

Questions about Southwick
Is hospital work, at somewhere like Southlands Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Southwick outside your area?
No. Places such as Southwick are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you provide access for facade work?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll plan the work with you.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
