About our facade sealing in Soho
External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames, and what we are called in for most is gaps between rainscreen or cladding panels and old perimeter mastic that has dried out. For commercial sealant work in Soho, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around Soho, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Record the product and colour used on each elevation
- Insist on a full cut-out when joints are renewed
- Report water ingress at frames as soon as it shows
- Share access with other external trades
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
Surface by surface
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.
Soho: questions and answers
Can work at a site such as University of Notre Dame fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you cover business parks and estates near Soho, such as Grand Vitesse Industrial Estate?
Yes. Estates, retail parks and business parks around Soho, Grand Vitesse Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Is Soho in your area?
Yes. We take on work across Soho, with one number for every area we cover.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Do you replace failed glazing units?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Providing access systems for the work
- Replacing glass or failed glazing units
- Movement beyond what any sealant can handle
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.

Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- 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.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Move anything stored against the joints
- Arrange parking or a loading space
- Point out any areas we must not close
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email drawings and photos.

New build and refits around Soho
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Soho. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Soho has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor at a hotel such as The Piccadilly London West End Hotel, under half a mile south-west of Soho, the mastic often has to be finished before a reopening date. Building work at universities like University of Notre Dame, less than half a mile to the south of Soho, is often timed for the summer, mastic included. New wings at hospitals like Royal London Hospital for Integrated Medicine, 0.7 miles to the north-east of Soho, bring long runs of window and panel joints to seal.
