How we handle facade sealing in Northfleet Green
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. The enquiries we see most involve discoloured or dirty facade joints and new sealant peeling off old mastic, on coping and flashing joints, stone and brick facade joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: in Northfleet Green, that means joint design, primers and backing rod as standard.
Around smaller places like Northfleet Green, building work usually 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Building and refurbishing in Northfleet Green
Rainfall across the South East, Northfleet Green included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. At about 19 miles from central London, Northfleet Green is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
On a healthcare site such as Gravesham Community Hospital, 2.3 miles to the north-east of Northfleet Green, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a college like North West Kent College, 2.8 miles north-east of Northfleet Green, perimeters and internal sealant are timed for the holidays.

What the job involves on each surface
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Northfleet Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- 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.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- Let us know about inductions and permits
- Tell us which areas need to stay in use

Signs you need facade sealing in Northfleet Green
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Most enquiries start with something like this:
- Failed seals around shopfront and entrance frames
- Weathered facade joints that have lost their grip
- Air leaks through failed facade joints
- Facade joints cracked through the middle
University estates such as University of Greenwich, 3.4 miles north-west of Northfleet Green, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
What to look for in a quote
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- Will CSCS-carded applicators be on site?
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Work on the window or framing system itself
- Cracked or spalling substrates that need repair before sealing
- Joints too narrow for the movement they take, which need redesign
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Shopfront frames
- Coping and flashing joints
- Cladding panel joints
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Report water ingress at frames as soon as it shows
- Share access with other external trades
- Inspect facade joints on a regular cycle
- Confirm the survey covers external sealants in older buildings
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
