Facade sealing in Cranbrook
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Cranbrook. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve staining on stone next to old sealant and air leaks through failed facade joints, on stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints. Most enquiries from Cranbrook start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Cranbrook 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

What we are called out for in Cranbrook
Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.
Typical triggers for a call:
- Cladding panel joints that have opened up
- Perimeter joints where frames meet the structure
- New sealant peeling off old mastic
- Facade joints cracked through the middle
Extensions at sites like Goodmayes Hospital, 2.2 miles east of Cranbrook, typically sit beside working departments, and the mastic follows strict access rules.

Cranbrook: questions and answers
Will you plan work around the academic year at somewhere like University of East London?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How much does the work cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you cover Cranbrook?
Yes. Cranbrook is in our area. To discuss a job, phone 01277 525 020 or email us.
Different surfaces, different methods
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish.
Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
Facade sealing around Cranbrook: what changes locally
There are a good number of hotels within about 2 miles of Cranbrook. 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 Cranbrook. Deliveries are booked and storage is tight, so mastic materials come in as needed.
When a college such as Mount Rose College, under half a mile north of Cranbrook, builds or refurbishes, the mastic package normally has to fit around students and staff. When units on a site such as Newbury Retail Park (to the north-east of Cranbrook) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Cranbrook is about 2 miles north-east of Forest Gate, in Greater London. Commercial clients in Cranbrook use us for work on facade joints, as part of our coverage of Greater London.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Damp caused by condensation inside the building
- Installing or repairing glazing systems
- Damaged frames that need replacing

How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000

Advice

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Avoid patch repairs on failed facade joints
- Keep pressure washers away from fresh sealant
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
