Contractors’ notes for Turnpike Lane

The area within 2 miles of Turnpike Lane holds a good number of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. As part of Greater London, Turnpike Lane is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed.

Units on estates such as Arena Shopping Park, 1 mile south-east of Turnpike Lane, 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 White Lodge Hotel (0.5 miles south-west of Turnpike Lane), normally run between busy periods, so the sealing is squeezed into short windows.

Turnpike Lane is about 3 miles north of Highbury, in Greater London. Across the N8 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 764 places across Greater London fall within our area, including Turnpike Lane.

Facade sealing for commercial buildings in Turnpike Lane

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with cold air coming in at window perimeters and new sealant peeling off old mastic, we can put it right, on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure alike. For commercial sealant work in Turnpike Lane, you deal with one contact from quote to sign-off, whether it’s one building or several.

Every London site, Turnpike Lane included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email the details over and we will come back to it.

Leave it or put it right?

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. In Turnpike Lane, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For a job in Turnpike Lane, access comes first: 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. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  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.

Before we start on site

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Advice

How the job changes by surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Questions we’re asked in Turnpike Lane

Can you work at a site such as Arena Shopping Park, by Turnpike Lane?

Yes, sites like Arena Shopping Park are within our area, along with the rest of Turnpike Lane. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like St Ann's Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

After the work

Once the work is signed off, these steps help:

  • Don’t wait for a second leak before calling
  • Plan facade sealing alongside redecoration
  • Ask about asbestos in pre-2000 mastic
  • Keep pressure washers away from fresh sealant

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Signs you need facade sealing in Turnpike Lane

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

Site and facilities staff are often the first to spot these:

  • Previous reseals run over old sealant
  • Discoloured or dirty facade joints
  • Failed sealant on precast panel joints
  • Water coming in around window frames

On a campus such as American University in London, which lies south of Turnpike Lane, new teaching buildings and residences are typically built and refurbished around the academic year.
