Gallows Corner: questions and answers

Do you take on jobs in Gallows Corner where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Is a hospital such as Victoria Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will rain stop the work?

Rain and frost can pause external sealing. We plan for weather and keep you updated.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Facade sealing in Gallows Corner

Managing agents and owners in Gallows Corner ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints, and the usual reasons a site gets in touch are discoloured or dirty facade joints and sealant pulling away from frames or panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Gallows Corner is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction in a London area such as Gallows Corner means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

On site: what to expect

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 move on in phases so staff and visitors can carry on around us. For a job in Gallows Corner, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

Advice

How the job changes by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Quoting for work in Gallows Corner

Your fixed quote is built from the real scope. It takes account of:

  • How much there is to seal
  • The size and state of each joint
  • Whether the work must be split into stages
  • Distance, for remote addresses

Pricing facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • The postcode of the building
  • When you need the work done
  • The product your specification calls for
  • Photos of the joints, close up and from further back

To get a fixed quote, phone 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Water getting in through cracked render or porous masonry
  • Cracked or spalling substrates that need repair before sealing
  • Providing access systems for the work

Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly.

Joints and surfaces we work on

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

Sites and facades in and around Gallows Corner

Gallows Corner has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, Gallows Corner is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

For contractors at a college like New City College (0.9 miles south-east of Gallows Corner), perimeters and internal sealant are timed for the holidays. Units on estates such as Rom Valley Retail Park (2 miles south-west of Gallows Corner) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Hotel extensions and refits, at places such as Park Hotel Essex, which lies south-west of Gallows Corner, typically run between busy periods, so the sealing is squeezed into short windows.
