About our facade sealing in Finsbury
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. If you’re dealing with facade joints cracked through the middle and draughts around frames and panels, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Finsbury is the same: the right product in a properly prepared joint.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Do you need facade sealing in Finsbury?
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Site and facilities staff are often the first to spot these:
- Hard, chalky sealant that no longer flexes
- Patch repairs that keep failing
- Sealant pulling away from frames or panels
- Failed seals around shopfront and entrance frames
For contractors refurbishing units at places like Southwark Bridge Business Centre, which lies south of Finsbury, the mastic covers cladding panels, roller-door and window perimeters.
What your quote should include
- Their plan for phasing and protecting the area

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- Any access equipment needed

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What else we do in Finsbury
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Building and refurbishing in Finsbury
The area within 2 miles of Finsbury holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The ULEZ covers the whole of Greater London, Finsbury included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For contractors on a campus like The University of Law (less than half a mile east of Finsbury), facade and perimeter sealing has to fit around students and term dates. New wings at hospitals like Moorfields Eye Hospital (City Road campus), less than half a mile north of Finsbury, bring long runs of window and panel joints to seal.

What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Arranging specialist high-level access, which is planned with the client
- Joints too narrow for the movement they take, which need redesign
- Damaged frames that need replacing
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
What we seal
- Shopfront frames
- Cladding panel joints
- Coping and flashing joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a job in Finsbury, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Send your site hours and access windows
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

Advice
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
