Facade sealing for commercial buildings in Arkley
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about old perimeter mastic that has dried out and previous reseals run over old sealant, on window and door perimeters, shopfront frames and coping and flashing joints. Whoever orders the work in Arkley, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Every London site, Arkley included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance
Quotes

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Avoid patch repairs on failed facade joints
- Combine resealing with other works that need access
- Keep sills, gutters and drainage paths clear
- Walk the elevations once or twice a year
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
Arkley: questions and answers
Do you take on jobs in Arkley where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Could you schedule work at a campus like Middlesex University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Facade sealing in Arkley: the local picture
Site traffic in Arkley falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. A 2-mile radius around Arkley takes in several hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
With historic properties like Wyllyotts Manor, 3.7 miles north-east of Arkley, in the area, refurbishment work often meets old masonry that needs compatible sealants. Building work at universities like Middlesex University (3.6 miles south of Arkley) is often timed for the summer, mastic included.
Arkley is about 2 miles west of Barnet, in Greater London. We send applicators to Arkley for facade joints, handled exactly as we handle every other area. Across Greater London, 764 places are covered, including Arkley. Our London page has more on work in that area (12 miles or so).

What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Installing or repairing glazing systems
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If you’re not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer.
Joints and surfaces we work on
- Window and door perimeters
- Shopfront frames
- Coping and flashing joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- Phasing around occupants
- Site requirements such as inductions and permits
- How accessible the joints are
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Any specification or named product
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- What the building is and how it’s used
To get a fixed quote, ring 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
What we’re called out for in Arkley
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.
What tends to prompt an enquiry:
- Failed seals around shopfront and entrance frames
- Facade joints cracked through the middle
- Staining on stone next to old sealant
- Cladding panel joints that have opened up
For a contractor working at a hospital such as Barnet Hospital, 0.7 miles to the east of Arkley, perimeter and facade sealing is planned around patients and deliveries.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- How long is the guarantee, and what does it include?

How the job changes by surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.
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, as the specification sets out.
