Facade sealing in South Bermondsey

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and what we are called in for most is air leaks through failed facade joints and perimeter sealant that has split or peeled away. A specialist sealant contractor works differently from a general builder: on jobs in South Bermondsey, preparation and product choice get the time they need.

Construction in a London area such as South Bermondsey means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Facade sealing around South Bermondsey: what changes locally

Plenty of hotels sit less than 2 miles from South Bermondsey. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in South Bermondsey falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

On a campus such as Northeastern University London, 1.5 miles to the north-west of South Bermondsey, new teaching buildings and residences are normally built and refurbished around the academic year. Extensions at sites like Guy's Hospital, 1.7 miles to the north-west of South Bermondsey, normally sit beside working departments, and the mastic follows strict access rules.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.

Your questions answered

Can work at a site such as Northeastern University London fit around teaching?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you work in South Bermondsey?

Yes. Sites across South Bermondsey are covered, with one number for every area we cover.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

Do you install glazing systems?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in South Bermondsey, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Advice

Do you need facade sealing in South Bermondsey?

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Look out for the following:

  • Sealant pulling away from frames or panels
  • Draughts around frames and panels
  • Previous reseals run over old sealant
  • Weathered joints at frame-to-structure perimeters

For a contractor at a hotel such as Peckham Rooms Hotel, which lies south of South Bermondsey, the mastic often has to be finished before a reopening date.

Comparing quotes

  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed
  • Will failed sealant be removed rather than covered?
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Why deal with it now?

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, often turning up far from the joint. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • 12-month guarantee on workmanship
  • Failed material removed, not covered up
  • CSCS-carded applicators
  • CHAS accredited contractor
