Facade sealing near Mildmay
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
What we need from you
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings

Advice
Facade sealing in Mildmay, done properly
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. If you have weathered joints at frame-to-structure perimeters and sealant pulling away from frames or panels, we can put it right. For commercial sealant work in Mildmay, you deal with one contact from quote to sign-off, whether it’s one building or several.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Mildmay can form part of a wider programme across Greater London.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
What the job involves on each surface
Precast concrete panels
Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported first.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.
Sites and facades in and around Mildmay
Site traffic in Mildmay falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are plenty of hotels within about 2 miles of Mildmay. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Further education sites such as City & Islington College (1.3 miles north-west of Mildmay) are extended and refurbished from time to time, with mastic often programmed into the summer break. Extensions at sites like Mildmay Mission Hospital, 1.5 miles to the south of Mildmay, normally sit beside working departments, and the mastic follows strict access rules. Units on estates such as Frogmore Industrial Estate, 0.6 miles north-west of Mildmay, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Mildmay is about 1 mile north of Hoxton, in Greater London. We cover commercial sites throughout Mildmay, whether it’s a single job or part of a planned programme. 764 places across Greater London fall within our area, Mildmay among them.
We cover the N1, N16 and E8 postcode districts for facade joints. Buildings on Dove Road, Essex Road and Burma Road are within our area for facade joints. You will find Mildmay on or near the A1199. We also cover Newington Green (1 mile north), De Beauvoir Town (1 mile south), Canonbury (1 mile south-west), Kingsland (1 mile south-east) and Highbury (1 mile west). Nearby towns on our patch include London (3 miles south), City of Westminster (4 miles south-west), Marylebone (3 miles south-west), Kensington (6 miles south-west), Walthamstow (4 miles north-east) and Hampstead (4 miles west).
What’s near Mildmay
We work on buildings around City of London Academy Highbury Grove, Highbury Fields and Army and Navy pub, among other places. Mildmay has its own railway station: Dalston Kingsland station. A little further out are Clowns Gallery-Museum (0.6 miles south-east) and Hackney Walk (1.5 miles east). The countryside around Mildmay includes Gillespie Park and Ludgate Hill.
Leave it or put it right?
Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds. Getting scaffold, permits or access booked in Mildmay takes effort, so it makes sense to deal with every failing joint while access is in place.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Questions we are asked in Mildmay
Can you work at a site such as Frogmore Industrial Estate, by Mildmay?
Yes. Our area takes in Mildmay and its surroundings, with estates and business parks such as Frogmore Industrial Estate included. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Mildmay Mission Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The total length or number of joints
- Removal of failed or old sealant
- Any access equipment needed
- Travel to remote or island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
We can often quote from photographs and a few details. Please tell us:
- When you need the work done
- Anything awkward about access or site hours
- The postcode of the building
- Photos of the joints, close up and from further back
For a fixed quote, give us a call on 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
