Facade sealing for Sprat's Down sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Building and refurbishing in Sprat's Down
Sprat's Down lies within about 1 mile of the sea. 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. Sprat's Down sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
New wings at hospitals like Coldeast (to the north-east of Sprat's Down) bring long runs of window and panel joints to seal. When units on a site such as Glenmore Business Park, 2.9 miles north-west of Sprat's Down, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Facade sealing in Sprat's Down
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. Site teams most often ask us about air leaks through failed facade joints and leaks at window and door perimeters, on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints. One point of contact handles commercial sealant work in Sprat's Down from the first photographs to the final walk-round, whether it’s one building or several.
Around smaller places like Sprat's Down, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- The total length or number of joints
- Access and working height
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:

- Anything awkward about access or site hours
- Whether an asbestos survey exists

What we are called out for in Sprat's Down
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
Site and facilities staff are often the first to spot these:
- Previous reseals run over old sealant
- Cold air coming in at window perimeters
- Hard, chalky sealant that no longer flexes
- Leaks at window and door perimeters
Historic houses such as Beaulieu Palace House, 4.7 miles west of Sprat's Down, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint

Questions we are asked in Sprat's Down
Does a coastal location like Sprat's Down affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Is Sprat's Down off your patch?
Not at all. Sprat's Down is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you work while the building is occupied?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
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.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Sprat's Down are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance

Surface by surface
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
After the work
For the best life from the joints:
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Record the product and colour used on each elevation
- Insist on a full cut-out when joints are renewed
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
