From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Planning a London job such as one in Noak Hill starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- 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.
Before we start on site
- Point out any areas we must not close
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work

Facade sealing for commercial buildings in Noak Hill
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. Site teams most often ask us about leaks at window and door perimeters and failed sealant on precast panel joints, across perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints. One point of contact handles commercial sealant work in Noak Hill from the first photographs to the final walk-round, whether it’s one building or several.
Construction in a London area such as Noak Hill means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

FAQs: Noak Hill
Would you work within a site like Hartswood Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can work at a site such as Havering Technical College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
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.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.
What we’re called out for in Noak Hill
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Things that usually lead to an enquiry:
- Cladding panel joints that have opened up
- Leaks at window and door perimeters
- Patch repairs that keep failing
- Perimeter sealant that has split or peeled away
Historic houses such as Hare Hall, 2.5 miles south-west of Noak Hill, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Add perimeter sealant to planned maintenance checks
- Record the product and colour used on each elevation
- Brief window cleaners about newly sealed joints
- Insist on a full cut-out when joints are renewed
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly with a compatible product.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.
New build and refits around Noak Hill
The ULEZ covers the whole of Greater London, Noak Hill included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in.
When a college such as Havering Technical College, under half a mile south of Noak Hill, builds or refurbishes, the mastic package usually has to fit around students and staff. On a healthcare site such as Hartswood Hospital (2.9 miles south-east of Noak Hill), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

When to bring in a specialist
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Different surfaces, different methods
Precast concrete panels
Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.
