Facade sealing in Angell Town, done properly
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, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. Most enquiries involve leaks at window and door perimeters and cladding panel joints that have opened up, across perimeter joints where frames meet the structure, shopfront frames and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Angell Town, that means joint design, primers and backing rod as standard.
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, so tidy, well-planned work matters.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we will come back to it.

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
When to call us in Angell Town
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
Any of the following is a good reason to get the joints checked over:
- Discoloured or dirty facade joints
- Previous reseals run over old sealant
- Weathered joints at frame-to-structure perimeters
- Weathered facade joints that have lost their grip
When a college such as William Booth College (to the east of Angell Town) builds or refurbishes, the mastic package normally has to fit around students and staff.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
- What site paperwork they can supply
- Whether old or failed sealant will be cut out, not overlaid
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What sets the cost
We price every job individually. The things that drive the figure:
- Location, for remote and island sites
- How accessible the joints are
- The size and state of each joint
- How much there is to seal
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Any dates the work must fit around
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or ring 01277 525 020 or send details through our quote form if you’d rather talk the job through.
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Angell Town can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- Flag any permit to work we’ll need
- Confirm the product named in the specification

Facade sealing in Angell Town: the local picture
As part of Greater London, Angell Town is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Angell Town takes in a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For a contractor at a hotel such as Loughborough Hotel (under half a mile north-east of Angell Town), the mastic often has to be finished before a reopening date. Units on estates such as KCH Business Park (to the east of Angell Town) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Angell Town is about 1 mile east of Stockwell, in Greater London. Any commercial site in Angell Town is covered, whether it’s a single job or part of a planned programme. Angell Town is one of 764 places in Greater London on our list.

Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Can work at a site such as King's College London fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
How many days will you need on site?
It depends on the scope, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Check the asbestos register before old mastic is disturbed
- Keep the sealant details on the building file
- Report water ingress at frames as soon as it shows
- Avoid harsh cleaners on facade sealant
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
