Facade sealing in Barnsbury
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. The enquiries we see most involve old perimeter mastic that has dried out and water coming in around window frames, on window and door perimeters, coping and flashing joints and shopfront frames. Whoever orders the work in Barnsbury, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Barnsbury must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
What we need from you
- Point out parking and an unloading spot
- Send your site hours and access windows
- Tell staff and tenants when we’ll be in

Related advice
Keeping the joints sound
For the best life from the joints:
- Insist on a full cut-out when joints are renewed
- Brief window cleaners about newly sealed joints
- Confirm the survey covers external sealants in older buildings
- Add perimeter sealant to planned maintenance checks
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Joints whose design needs changing by the specifier
- Cracked or spalling substrates that need repair before sealing
- Water getting in through cracked render or porous masonry
Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly before you book.
What we seal

When to bring in a specialist
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.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What the job involves on each surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Can you work at a site such as Roman Way Industrial Estate, by Barnsbury?
Yes. Estates, retail parks and business parks around Barnsbury, Roman Way Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Do you take on work at healthcare sites like St. Pancras Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can give us a call on 01277 525 020 or send photos by email to arrange a visit. Many frame leaks are sealant failures, though not all, and we will tell you which.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you work in cold or wet weather?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things throughout the job.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
