Facade sealing in Holloway
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. The enquiries we see most involve staining on stone next to old sealant and patch repairs that keep failing, across window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure. Whoever orders the work in Holloway, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for facade joints
Each job is priced on its own details. The main factors are:
- Whether old sealant has to be cut out first
- How much there is to seal
- Whether the work must be split into stages
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs

New build and refits around Holloway
As part of Greater London, Holloway is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. The area within 2 miles of Holloway holds a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Projects at colleges like City and Islington College (under half a mile west of Holloway) tend to run to term dates, so the mastic is planned tightly. Building work at universities like American University in London (less than half a mile north-east of Holloway) is often timed for the summer, mastic included.
Holloway is about 2 miles north-west of Hoxton, in Greater London. Looking for facade sealing in Holloway? We can help, as we do across Greater London. Holloway is one of 764 places in Greater London on our list for facade joints.

Holloway: questions and answers
Is a hospital such as The Whittington Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Can work at a site such as American University in London fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Do you cover Holloway?
Yes. We cover Holloway. To discuss a job, call the office on 01277 525 020 or email us.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, saving a second set-up. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Commercial clients in Holloway
We work for building owners and managing agents on everything from one building to a spread of sites around Holloway. Several sites can go on one quote, which keeps the paperwork simple.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Holloway can form part of a wider programme across Greater London.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Don’t wait for a second leak before calling
- Insist on a full cut-out when joints are renewed
- Confirm the survey covers external sealants in older buildings
- Keep pressure washers away from fresh sealant
After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
When to call us in Holloway
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
Most enquiries start with one or more of the following:
- Facade joints cracked through the middle
- Patch repairs that keep failing
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
New wings at hospitals like The Whittington Hospital (1.2 miles north-west of Holloway) bring long runs of window and panel joints to seal.
