Facade sealing for commercial buildings in New Cross
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. We work on coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure, and the failures we are asked to look at most are water coming in around window frames and unsightly perimeter sealant on a visible elevation. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in New Cross, that means joint design, primers and backing rod as standard.
Around New Cross, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why act early in New Cross
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Getting scaffold, permits or access booked in New Cross takes effort, so it makes sense to deal with every failing joint while access is in place.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Why appoint us
- A Constructionline member, so easy to vet
- Health and safety: CHAS accredited
- Public liability insurance in place
- Colours chosen to suit frames, cladding or finishes where possible

Facades, frames and programmes in New Cross
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in New Cross. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around New Cross takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Extensions at sites like University Hospital Lewisham (to the south-east of New Cross) typically sit beside working departments, and the mastic follows strict access rules. Work at a hotel such as Peckham Rooms Hotel, 1.3 miles west of New Cross, tends to be programmed around bookings, mastic included. New units and refits on sites such as New Cross Gate Retail Park, 0.5 miles north-west of New Cross, need their panel and perimeter joints sealed to the specification.

Your questions answered
Could you schedule work at a campus like University of Greenwich - Greenwich Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is New Cross Gate Retail Park, near New Cross, within your area?
Yes. We cover New Cross and the area around it, including industrial estates, business parks and retail parks such as New Cross Gate Retail Park. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. That is what makes the new joint last.
What do you charge?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you install glazing systems?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
Maintenance after handover
For the best life from the joints:
- Check that rainwater leaves the facade the way it was designed to
- Walk the elevations once or twice a year
- Share access with other external trades
- Avoid patch repairs on failed facade joints
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
How the job changes by surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

From enquiry to sign-off
Working in a building that stays open takes some planning. 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 are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Access, site rules and timing are settled with the client up front.
- 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.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Flag any permit to work we will need
- Point out any areas we must not close
- Send asbestos survey details if the building is pre-2000
