What we are called out for in Fenn Street
When the sealant tears down its centre, it has usually been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
It’s worth sending us details if you spot any of the following:
- Failed seals around shopfront and entrance frames
- Discoloured or dirty facade joints
- Facade joints cracked through the middle
- Hard, chalky sealant that no longer flexes
For contractors at a school such as High Halstow Primary Academy, sealing has to be finished before term starts.
Questions to ask before you book
- The named product and why it was chosen
- How they’ll work around occupants
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
Facade sealing for commercial buildings in Fenn Street
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Fenn Street. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve new sealant peeling off old mastic and cladding panel joints that have opened up, across stone and brick facade joints, cladding panel joints and coping and flashing joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Fenn Street it comes down to the same thing: the right product in a properly prepared joint.
Conversions of older rural buildings near smaller places such as Fenn Street 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Fenn Street: questions and answers
Is hospital work, at somewhere like Medway Maritime Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as University of Greenwich - Medway fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can you work on upper floors?
That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will plan the work with you.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Which sealant do you use on facades?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Cost factors for facade joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The size and state of each joint
- How much there is to seal
- Working within restricted access windows
- Location, for remote and island sites
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- The postcode of the building
- Drawings or a marked-up plan, if available
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Surface by surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. For work around Fenn Street, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- 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.
Before we start on site
- Point out any areas we must not close
- Move anything stored against the joints
- Let us know about inductions and permits

What else we do in Fenn Street
Maintenance after handover
After handover, a little attention goes a long way:
- Ask about asbestos in pre-2000 mastic
- Plan facade sealing alongside redecoration
- Report water ingress at frames as soon as it shows
- Keep pressure washers away from fresh sealant
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
Contractors’ notes for Fenn Street
With the shore within about 2 miles, Fenn Street counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. At about 29 miles from central London, Fenn Street is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
Extensions at sites like Medway Maritime Hospital (to the south of Fenn Street) usually sit beside working departments, and the mastic follows strict access rules. For contractors on a campus like University of Greenwich - Medway, 3.9 miles to the south-west of Fenn Street, facade and perimeter sealing has to fit around students and term dates.
Fenn Street is about 5 miles north of Gillingham, in Medway. Our applicators travel to Fenn Street for work on facade joints. Our Medway coverage takes in 54 places, from busy centres to rural villages. Sites around London have their own page, roughly 29 miles from Fenn Street.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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 usually costs more in the end than doing them right.
