Facade sealing for Seven Dials sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Cost factors for facade joints
Each job is priced on its own details. The things that drive the figure:
- Site requirements such as inductions and permits
- How much there is to seal
- Joint width, depth and condition
- Travel to remote or island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Whether the building will be occupied during the work
- Any specification or named product
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Facade sealing for commercial buildings in Seven Dials
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on coping and flashing joints, perimeter joints where frames meet the structure and window and door perimeters, and the usual reasons a site gets in touch are new sealant peeling off old mastic and hard, chalky sealant that no longer flexes. A single leaking joint is often how a building in Seven Dials first comes to us: we look at the rest while we’re there and tell you what we find.
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.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. All of Greater London is in the ULEZ, and kerbside space in Seven Dials can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies 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
- Share your working hours and any access restrictions
- Flag any permit to work we will need
- Send any specification or drawings in advance

Facade sealing in Seven Dials: the local picture
There are plenty of hotels within about 2 miles of Seven Dials. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Seven Dials. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Units on estates such as Grand Vitesse Industrial Estate (1.3 miles south-east of Seven Dials) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Hospital estates such as Royal London Hospital for Integrated Medicine (to the north of Seven Dials) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Seven Dials is about 1 mile east of City of Westminster, in Greater London. Our applicators travel to Seven Dials for work on facade joints, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places, large and small.

Do you need facade sealing in Seven Dials?
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.
Things that usually lead to an enquiry:
- Water coming in around window frames
- New sealant peeling off old mastic
- Discoloured or dirty facade joints
- Weathered joints at frame-to-structure perimeters
Projects at colleges like Scott's College, under half a mile north-west of Seven Dials, tend to run to term dates, so the mastic is planned tightly.

Questions about Seven Dials
Does your area include sites such as Grand Vitesse Industrial Estate, near Seven Dials?
Yes. We cover Seven Dials and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Do you take on work at healthcare sites like Royal London Hospital for Integrated Medicine?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect the work?
It can, when the joints are outside. 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.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you use silicone for external joints?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Looking after the joints
After handover, a little attention goes a long way:
- Keep sills, gutters and drainage paths clear
- Avoid patch repairs on failed facade joints
- Note when each elevation was last resealed
- Confirm the survey covers external sealants in older buildings
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
