Facade sealing in Enfield Lock

Managing agents and owners in Enfield Lock ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. If you’re dealing with perimeter sealant that has split or peeled away and previous reseals run over old sealant, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Enfield Lock is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Every London site, Enfield Lock included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing
  • Specialist high-level access methods

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Joints and surfaces we work on

  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Cladding panel joints
  • Shopfront frames
  • Coping and flashing joints
  • Stone and brick facade joints

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

When to call us in Enfield Lock

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Most enquiries start with one or more of the following:

  • Old perimeter mastic that has dried out
  • Gaps between rainscreen or cladding panels
  • Perimeter sealant that has split or peeled away
  • Patch repairs that keep failing

Older buildings in the area around Enfield Lock, such as Forty Hall (1.8 miles west of Enfield Lock), need care when sealed: the product has to suit soft or historic materials.

Questions to ask before you book

  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?
  • How the existing material will be dealt with
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

Common questions from Enfield Lock clients

Is hospital work, at somewhere like Cheshunt Community Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Will you take on work at estates like Waterways Business Centre, close to Enfield Lock?

Yes. Estates, retail parks and business parks around Enfield Lock, Waterways Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we will price the work around it.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Planning a London job such as one in Enfield Lock starts with access. Send the building rules and access times with your enquiry.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Make sure the joints can be reached
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work
