How we handle facade sealing in Bow

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you have perimeter joints where frames meet the structure and patch repairs that keep failing, we can help, on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints alike. One point of contact handles commercial sealant work in Bow from the first photos to the final walk-round, whether it’s one building or several.

Sites around smaller places like Bow can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

Work we carry out in Oxfordshire comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Bow need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand
  • Move anything stored against the joints

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

What affects the price in Bow

The price varies from site to site. Expect it to depend on:

  • Any access equipment needed
  • Removal of failed or old sealant
  • Phasing around occupants
  • The total length or number of joints

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • Specification clauses that apply
  • Whether an asbestos survey exists
  • The postcode of the building
  • Drawings or a marked-up plan, if available

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Installing or repairing glazing systems
  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

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

Questions we are asked in Bow

Is Bow too small for you to travel to?

No. Places such as Bow are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can work at a site such as University of Oxford fit around teaching?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.

Commercial clients in Bow

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Looking after the joints

Once the work is signed off, these steps help:

  • Never let anyone seal over old sealant
  • Avoid harsh cleaners on facade sealant
  • Walk the elevations once or twice a year
  • Investigate damp beside windows promptly

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facade sealing in Bow: the local picture

Bow is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. At about 61 miles from central London, Bow is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

When a school such as Stanford in the Vale Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. With historic properties like Longworth House, 4.3 miles north-east of Bow, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Signs you need facade sealing in Bow

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

It’s worth sending us details if you spot any of the following:

  • Staining on stone next to old sealant
  • Water coming in around window frames
  • Sealant pulling away from frames or panels
  • Failed sealant on precast panel joints

For a contractor working at a hospital such as Longworth Hospital (3.9 miles west of Bow), perimeter and facade sealing is planned around patients and deliveries.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?
