What sets the cost
To price the job, we consider:
- Site requirements such as inductions and permits
- The total length or number of joints
- Joint width, depth and condition
- Distance, for remote addresses
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Any specification or named product
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email drawings and photos.
Facade sealing in Horn Park
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 cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are failed sealant on precast panel joints and failed seals around shopfront and entrance frames. Most enquiries from Horn Park start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in a London area such as Horn Park means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Some joints are best left to specialists: for instance 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.

What else we do in Horn Park
FAQs: Horn Park
Can you work on a hospital site such as Eltham Community Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Horn Park, such as Chiltonian Industrial Estate?
Yes. We cover Horn Park and the area around it, including industrial estates, business parks and retail parks such as Chiltonian Industrial Estate. A few photos and the unit address let us price the work.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How many days will you need on site?
It depends on the scope, but the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Which sealant do you use on facades?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
Signs you need facade sealing in Horn Park
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.
Typical triggers for a call:
- Failed seals around shopfront and entrance frames
- Facade joints cracked through the middle
- Cold air coming in at window perimeters
- Discoloured or dirty facade joints
Hotels like Baring Hall Hotel, 1.1 miles south of Horn Park, rarely close for long, so refurbishment mastic is phased floor by floor.
Comparing quotes
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Cracked or spalling substrates that need repair before sealing
- Arranging specialist high-level access, which is planned with the client
- Damp caused by condensation inside the building
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints
- Shopfront frames
Maintenance after handover
For the best life from the joints:
- Avoid harsh cleaners on facade sealant
- Ask about asbestos in pre-2000 mastic
- Keep sills, gutters and drainage paths clear
- Never let anyone seal over old sealant
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- 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.

Advice
Mastic packages on Horn Park sites
Plenty of hotels sit less than 2 miles from Horn Park. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Horn Park. Delivery slots and scarce storage shape how and when the mastic goes in.
Further education sites such as Hadlow College (to the south of Horn Park) are extended and refurbished from time to time, with mastic often programmed into the summer break. University estates such as University of Greenwich - Avery Hill, 2.2 miles east of Horn Park, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
