How we handle facade sealing in Cock Marling
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. If you’re dealing with discoloured or dirty facade joints and water coming in around window frames, we can help, on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Cock Marling, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Cock Marling bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Aftercare for building managers
To get the most from the new sealant:
- Don’t wait for a second leak before calling
- Keep the sealant details on the building file
- Confirm the survey covers external sealants in older buildings
- Clear debris that holds water against joints
Keep a note of which product went in and when. Future work can then match the product and colour.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
Sites and facades in and around Cock Marling
The sea is no more than about 3 miles from Cock Marling. 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. Cock Marling is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
Historic houses such as Lamb House (to the east of Cock Marling) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Installing or repairing glazing systems
- Joints whose design needs changing by the specifier
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.

What the job involves on each surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Cock Marling need work, visits can be combined. You will have a fixed quote before work starts.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- 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.
What we need from you
- Tell us which areas need to stay in use
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs

What we’re called out for in Cock Marling
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.
What tends to prompt an enquiry:
- Cold air coming in at window perimeters
- Old perimeter mastic that has dried out
- Facade joints cracked through the middle
- Previous reseals run over old sealant
New units and refits on sites such as Jempson Trading Estate (2.3 miles east of Cock Marling) need their panel and perimeter joints sealed to the specification.

Cock Marling: questions and answers
Is a smaller place like Cock Marling outside your area?
No. Places such as Cock Marling are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Our building in Cock Marling is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
What do you charge?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
