Facade sealing for commercial buildings in Harrietsham
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. We will tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve gaps between rainscreen or cladding panels and air leaks through failed facade joints, across shopfront frames, stone and brick facade joints and window and door perimeters. A single leaking joint is often how a building in Harrietsham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions around smaller places like Harrietsham often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.
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.
New build and refits around Harrietsham
Harrietsham sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. At about 38 miles from central London, Harrietsham is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
For contractors refurbishing units at places like Roebuck Business Park, under half a mile to the west of Harrietsham, the mastic covers cladding panels, roller-door and window perimeters. University estates such as Canterbury Christ Church University, 1.7 miles to the north of Harrietsham, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. With historic properties like Leeds Castle, 2.2 miles west of Harrietsham, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Cost factors for facade joints
To price the job, we consider:
- Whether old sealant has to be cut out first
- How accessible the joints are
- The site’s rules and procedures
- How much there is to seal
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- The postcode of the building
- A wide shot and a close-up of the area
- Drawings or a marked-up plan, if available
- Any dates the work must fit around

Why deal with it now?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. For buildings in places like Harrietsham, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

FAQs: Harrietsham
Is Harrietsham too small for you to travel to?
No. Places such as Harrietsham are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Roebuck Business Park, near Harrietsham?
Yes. We cover Harrietsham and the area around it, including industrial estates, business parks and retail parks such as Roebuck Business Park. Photos and a short description are enough for a first look.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
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.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you seal facades in winter?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a job in Harrietsham, the main thing is a clear picture of the work. A fixed quote follows.
- 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.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Let building users know which areas are affected
- Send any specification or drawings in advance
