How a job runs

- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.

Facade sealing for commercial buildings in Ashington
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. Most enquiries involve perimeter sealant that has split or peeled away and failed seals around shopfront and entrance frames, across cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure.

Facade sealing in Ashington: the local picture
At about 41 miles from central London, Ashington is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Ashington included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Projects at schools like Ashington CofE Primary School work to term dates, so mastic is programmed tightly. Recladding or extending a unit at a site like Wiston Business Park (0.9 miles south-west of Ashington) brings panel joints and frame perimeters into the programme.
Ashington is about 8 miles north of Worthing, in West Sussex. Across the RH20 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our West Sussex coverage takes in 373 places, large and small. Our Brighton page has more on work in that area, about 13 miles away.

FAQs: Ashington
Is Wiston Business Park, near Ashington, within your area?
Yes. Estates, retail parks and business parks around Ashington, Wiston Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is Ashington too small for you to travel to?
Not at all. Ashington is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How is access to upper-level joints handled?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we will plan the work with you.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Joints too narrow for the movement they take, which need redesign
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
What we seal
- Cladding panel joints
- Coping and flashing joints
- Stone and brick facade joints
- Window and door perimeters
- Shopfront frames
- Perimeter joints where frames meet the structure
What we’re called out for in Ashington
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
If one of these sounds familiar, it’s time for a closer look:
- Perimeter sealant that has split or peeled away
- New sealant peeling off old mastic
- Draughts around frames and panels
- Old perimeter mastic that has dried out
Historic houses such as Parham House (to the west of Ashington) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
What your quote should include
- Their approach to joint depth and backing
- How they’ll work around occupants
- The named product and why it was chosen
- What the guarantee covers, and for how long
After the work
For the best life from the joints:
- Add perimeter sealant to planned maintenance checks
- Investigate damp beside windows promptly
- Clear debris that holds water against joints
- Combine resealing with other works that need access
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Why act early in Ashington
Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Around Ashington, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
