Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Facade sealing in Adelphi, done properly
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. We work on cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are weathered facade joints that have lost their grip and facade joints cracked through the middle. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Adelphi is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Every London site, Adelphi included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Adelphi: questions and answers
Do you take on jobs in Adelphi where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Will you plan work around the academic year at somewhere like University of Notre Dame?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Aftercare for building managers
After handover, a little attention goes a long way:
- Add perimeter sealant to planned maintenance checks
- Avoid harsh cleaners on facade sealant
- Plan facade sealing alongside redecoration
- Report water ingress at frames as soon as it shows
Look at perimeter and panel joints as part of routine building checks. 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.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Send any specification or drawings in advance
- Let us know about inductions and permits
- Move anything stored against the joints

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Common problems we fix in Adelphi
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Things that usually lead to an enquiry:
- Leaks at window and door perimeters
- Cold air coming in at window perimeters
- Cladding panel joints that have opened up
- Previous reseals run over old sealant
On a healthcare site such as St Thomas' Hospital, which lies south of Adelphi, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Facades, frames and programmes in Adelphi
The area within 2 miles of Adelphi holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Adelphi. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For a contractor at a hotel such as Hotel Cecil (London) (less than half a mile north-east of Adelphi), the mastic often has to be finished before a reopening date. For contractors refurbishing units at places like Grand Vitesse Industrial Estate, 0.9 miles east of Adelphi, the mastic covers cladding panels, roller-door and window perimeters.

What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Removal of failed or old sealant
- Working within restricted access windows
- The site’s rules and procedures
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Whether an asbestos survey exists
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- The type of building and who uses it
