Facade sealing for Cobham sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What happens if it’s left?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. One visit to deal with every failing joint makes more sense than several trips to a place like Cobham. Photos of every joint help us quote for the whole job.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Why appoint us
- 12 months’ guarantee on every job
- Old sealant cut out, never sealed over
- Colour options checked against the specified product
- Work to your specification and the manufacturer’s guidance

Facade sealing for commercial buildings in Cobham
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. The enquiries we see most involve hard, chalky sealant that no longer flexes and previous reseals run over old sealant, on cladding panel joints, coping and flashing joints and shopfront frames. For commercial sealant work in Cobham, you deal with one contact from quote to sign-off, whether it’s one building or several.
Construction in and around smaller places such as Cobham is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What the job involves on each surface
Precast concrete panels
Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported first.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Access and working height
- The product specified
- How much existing material needs removing
- Travel to remote or island sites
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
What we need to price the job
However big the job, these details speed things up:
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- Whether an asbestos survey exists
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or send photos by email to discuss it first.
Contractors’ notes for Cobham
Cobham lies roughly 23 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
Projects at schools like Cobham Primary School work to term dates, so mastic is programmed tightly. Building work at universities like University for the Creative Arts - Rochester, 4.9 miles to the east of Cobham, is often timed for the summer, mastic included. For a contractor working at a hospital such as Gravesham Community Hospital, 3.9 miles to the north-west of Cobham, perimeter and facade sealing is planned around patients and deliveries.
Cobham is about 3 miles south of Gravesend, in Kent. Any commercial site in Cobham is covered, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, Cobham among them. London is covered too, around 23 miles from Cobham.

We also cover Upper Bush (2 miles south-east), Lower Bush (2 miles south-east), Cuxton (2 miles south-east), North Halling (3 miles south-east) and Upper Halling (3 miles south) for facade joints.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Cobham can be grouped with others nearby. A fixed quote is given before anything starts.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Warn occupants and staff about the work
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Advice
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Joints too narrow for the movement they take, which need redesign
- Providing access systems for the work
- Render or concrete edges that have broken away
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
FAQs: Cobham
Is hospital work, at somewhere like Gravesham Community Hospital, something you do?
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.
Does your area include sites such as Bowes Industrial Centre, near Cobham?
Yes. Estates, retail parks and business parks around Cobham, Bowes Industrial Centre among them, are all within reach. Photos and a short description are enough for a first look.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What hours do you work?
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 your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
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.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
