Expansion joint sealing for commercial buildings in Westbourne

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. Site teams most often ask us about debris jammed in movement joints and layers of sealant in a movement joint, on podiums and floor movement joints, precast concrete panel joints and blockwork control joints. Searching for sealant specialists in Westbourne? We have been sealing commercial buildings since 2005.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.

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

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.

Expansion joint sealing in Westbourne: the local picture

Westbourne has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

On industrial estates such as Stable Way Industrial Estate, 1.1 miles west of Westbourne, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Another example is Latimer Industrial Estate, 1.2 miles to the west of Westbourne, where floors and yards would be done in stages around the occupiers. Sites like St Mary's Hospital (to the east of Westbourne) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Westbourne is about 1 mile north of Kensington, in Greater London. Commercial clients in Westbourne can call on us for movement joints. Westbourne is one of 764 places we cover in Greater London.

Sites close to Westbourne are covered too, including Westbourne Green (1 mile north-east), Bayswater (1 mile south), Little Venice (1 mile north-east), Maida Vale (1 mile north) and Paddington Green (1 mile east).

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Keep traffic off new joints until the cure time is up
  • Keep racking legs and heavy point loads off floor joints
  • Keep stones and debris out of open joint lines
  • Keep scrapers and ploughs from dragging across joint sealant

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

If you are not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Blockwork control joints

Leave it or put it right?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

FAQs: Westbourne

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

Can you work on a hospital site such as St Mary's Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped, and the sealing method is much the same.

What happens if it rains on the day?

A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you seal car park deck joints?

Yes. Let us know the opening hours and which levels or bays have to stay available, and we will plan the phasing around it.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. Planning a London job such as one in Westbourne starts with access. Send the building rules and access times with your enquiry.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
