Facade sealing in Nunhead, 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 on commercial buildings in Nunhead. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve draughts around frames and panels and cladding panel joints that have opened up, on shopfront frames, perimeter joints where frames meet the structure and cladding panel joints. Whoever orders the work in Nunhead, 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 Nunhead must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.

Surface by surface
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, and mask the edges carefully.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Facades, frames and programmes in Nunhead
As part of Greater London, Nunhead is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. The area within 2 miles of Nunhead holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Work at a hotel such as Peckham Rooms Hotel, 1 mile north-west of Nunhead, tends to be programmed around bookings, mastic included. When units on a site such as Goose Green Trading Estate (to the west of Nunhead) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Nunhead is about 1 mile south-west of New Cross, in Greater London. Across the SE15 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Greater London, 764 places are covered, including Nunhead.

Commercial clients in Nunhead
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
What we are called out for in Nunhead
Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.
Things that normally lead to an enquiry:
- Patch repairs that keep failing
- Failed seals around shopfront and entrance frames
- Staining on stone next to old sealant
- Facade joints cracked through the middle
For contractors at a college like Christ the King: Aquinas Sixth Form College, which lies north-east of Nunhead, perimeters and internal sealant are timed for the holidays.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Replacing glass or failed glazing units
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. Planning a London job such as one in Nunhead starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
