Facade sealing in Blackgang
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure, and what we’re called in for most is water coming in around window frames and draughts around frames and panels. Facilities teams, main contractors and managing agents in Blackgang tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a site near Blackgang, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Your questions answered
Is Blackgang too small for you to travel to?
No. Places such as Blackgang are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work on a hospital site such as Whitecroft Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
How long does a job like this take?
It depends on the scope, but the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Do you need facade sealing in Blackgang?
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Most enquiries start with something like this:
- Leaks at window and door perimeters
- Perimeter sealant that has split or peeled away
- Failed seals around shopfront and entrance frames
- Staining on stone next to old sealant
On a healthcare site such as Whitecroft Hospital, which lies north of Blackgang, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- Their plan for phasing and protecting the area
- Will RAMS and insurance details be available?
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
Cost factors for facade joints
Each job is priced on its own details. The things that drive the figure:
- Access and working height
- Distance, for remote addresses
- Phasing around occupants
- Whether old sealant has to be cut out first
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Access details, including height
- Your programme or deadline
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
For a fixed quote, call 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Movement beyond what any sealant can handle
- Specialist high-level access methods
Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Shopfront frames
- Cladding panel joints
- Window and door perimeters
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
Owners, agents and contractors
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Blackgang may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- 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.
- We walk the finished joints with you before handing over.
Getting the site ready
- Send any specification or drawings in advance
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

What happens if it’s left?
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Halls, stores and units around places like Blackgang may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Contractors’ notes for Blackgang
Blackgang is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Blackgang included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
When a school such as Niton Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Historic houses such as Wolverton Manor, 4.1 miles to the north-west of Blackgang, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
