Facade sealing in St George's Fields
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you’re dealing with unsightly perimeter sealant on a visible elevation and leaks at window and door perimeters, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in St George's Fields it comes down to the same thing: the right product in a properly prepared joint.
Construction in a London area such as St George's Fields means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How the job changes by surface
Window and door perimeters
Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Damp caused by condensation inside the building
- Movement beyond what any sealant can handle
- Damaged frames that need replacing
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer.
Surfaces we seal
- Window and door perimeters
- Cladding panel joints
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Shopfront frames
What we’re called out for in St George's Fields
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
If one of these sounds familiar, it’s time for a closer look:
- Weathered facade joints that have lost their grip
- Discoloured or dirty facade joints
- Patch repairs that keep failing
- Draughts around frames and panels
For a contractor working at a hospital such as Evelina London Children's Hospital, which lies west of St George's Fields, perimeter and facade sealing is planned around patients and deliveries.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In St George's Fields, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Move anything stored against the joints

Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Hotels like The Bridge Hotel, less than half a mile east of St George's Fields, rarely close for long, so refurbishment mastic is phased floor by floor.

Quoting for work in St George's Fields
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Removal of failed or old sealant
- Travel to remote or island sites
- Induction, permit and paperwork requirements
Pricing facade joints depends on quantities, condition and access. Call for a quote.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- Any specification or named product
- Anything awkward about access or site hours
- Clear photos of the problem areas
- Whether an asbestos survey exists
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Add perimeter sealant to planned maintenance checks
- Don’t wait for a second leak before calling
- Clear debris that holds water against joints
- Share access with other external trades
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.
