Facade sealing in Bishopsgate, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. If you have patch repairs that keep failing and staining on stone next to old sealant, we can put it right, on window and door perimeters, shopfront frames and stone and brick facade joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Bishopsgate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Bishopsgate, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Do you need facade sealing in Bishopsgate?
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
It’s worth sending us details if you spot any of the following:
- Failed seals around shopfront and entrance frames
- Cladding panel joints that have opened up
- Water coming in around window frames
- Unsightly perimeter sealant on a visible elevation
For contractors on a campus like Royal Holloway University, 1.3 miles south-east of Bishopsgate, facade and perimeter sealing has to fit around students and term dates.
What to look for in a quote
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Will failed sealant be removed rather than covered?
Why act early in Bishopsgate
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. One visit to deal with every failing joint makes more sense than several trips to a place like Bishopsgate. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

- Fully insured
- CHAS accredited
- One phone line for London, the South East and Scotland

Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Joints whose design needs changing by the specifier
- Specialist high-level access methods
- Render or concrete edges that have broken away
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Window and door perimeters
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Stone and brick facade joints
- Shopfront frames
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Confirm the survey covers external sealants in older buildings
- Insist on a full cut-out when joints are renewed
- Share access with other external trades
- Keep pressure washers away from fresh sealant
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
Contractors’ notes for Bishopsgate
At about 22 miles from central London, Bishopsgate is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. There are several hotels within about 2 miles of Bishopsgate. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For a contractor working at a hospital such as King Edward VII Hospital (2.7 miles north-west of Bishopsgate), perimeter and facade sealing is planned around patients and deliveries. Hotels like The Lodge Hotel (0.8 miles south-east of Bishopsgate) rarely close for long, so refurbishment mastic is phased floor by floor.

What affects the price in Bishopsgate
Quotes vary with the job. Expect it to depend on:
- Quantities, in metres or numbers
- The product specified
- Location, for remote and island sites
- Site requirements such as inductions and permits
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Your questions answered
Can you work on a hospital site such as King Edward VII Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as The Green Business Centre, by Bishopsgate?
Yes. We cover Bishopsgate and the area around it, including industrial estates, business parks and retail parks such as The Green Business Centre. Photos and a short description are enough for a first look.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What will the job cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or email a schedule or drawings with a description of the work.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
