Facade sealing for commercial buildings in Dagenham Dock

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. If you’re dealing with cold air coming in at window perimeters and previous reseals run over old sealant, we can put it right, on coping and flashing joints, window and door perimeters and shopfront frames alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dagenham Dock is the same: the right product in a properly prepared joint.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.

Every job we finish is backed by a 12-month workmanship guarantee, in Dagenham Dock as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, 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 Dagenham Dock 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.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. 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.

What we need from you

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work

Advice

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. 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: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we’re asked in Dagenham Dock

Does your area include sites such as Merrielands Retail Park, near Dagenham Dock?

Yes. Estates, retail parks and business parks around Dagenham Dock, Merrielands Retail Park among them, are all within reach. Photos and a short description are enough for a first look.

Do you take on jobs in Dagenham Dock where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

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 cover Dagenham Dock?

Yes. We cover Dagenham Dock. To discuss a job, speak to us on 01277 525 020 or use the quote form.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Water getting in through cracked render or porous masonry
  • Providing access systems for the work
  • Replacing glass or failed glazing units

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

What we seal

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

When to call us in Dagenham Dock

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

What tends to prompt an enquiry:

  • New sealant peeling off old mastic
  • Weathered joints at frame-to-structure perimeters
  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters

When units on a site such as Merrielands Retail Park (to the north of Dagenham Dock) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • Their public liability cover

Our contractor checklist

What happens if it’s left?

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. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • One number for every site we cover
  • Coloured sealants to suit the setting, where available
  • CHAS accredited contractor
  • Failed material removed, not covered up

Read how commercial sealant jobs are priced and how we’re accredited.

What sets the cost

These are the things that shape the price:

  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • How much there is to seal
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The type of building and who uses it
  • Clear photographs of the problem areas
  • Any specification or named product
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or email us.
