FAQs: Sompting
Can you take on a job at a hospital such as Worthing Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Sompting outside your area?
No. Places such as Sompting are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or send photos by email. Include photos or drawings if you have them.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Facade sealing in Sompting
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are staining on stone next to old sealant and new sealant peeling off old mastic. Facilities teams, main contractors and managing agents in Sompting tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a smaller place such as Sompting, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Whether old sealant has to be cut out first
- The product specified
- The total length or number of joints
- Travel to remote or island sites
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- Drawings or a marked-up plan, if available
- The type of building and who uses it
- When you need the work done
- Access details, including height
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email us.
Mastic packages on Sompting sites
The sea is no more than about 2 miles from Sompting. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Sompting is about 47 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like Rectory Farm Road Business Park (to the north of Sompting) brings panel joints and frame perimeters into the programme. School extensions, at buildings such as Sompting Village Primary School, normally run to the summer holidays, mastic included.
Sompting is about 3 miles east of Worthing, in West Sussex. Our applicators travel to Sompting for work on facade joints, handled exactly as we handle every other area.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For a site in Sompting, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Let us know about inductions and permits
- Let building users know which areas are affected
- Arrange parking or a loading space

Related advice
What we’re called out for in Sompting
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Any of the following is a good reason to get the joints checked over:
- Leaks at window and door perimeters
- Previous reseals run over old sealant
- Weathered joints at frame-to-structure perimeters
- Cladding panel joints that have opened up
For a contractor at a hotel such as Beach Green Hotel, which lies south-east of Sompting, the mastic often has to be finished before a reopening date.
What to look for in a quote
- What the guarantee covers, and for how long
- How the existing material will be dealt with
- How they’ll work around occupants
- Which product they’ll use, and why it suits the joint
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Damp caused by condensation inside the building
- Joints too narrow for the movement they take, which need redesign
- Render or concrete edges that have broken away
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
Where we work in Sompting
- Window and door perimeters
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Shopfront frames
- Cladding panel joints
- Coping and flashing joints
What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed.
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
