Expansion joint sealing in Fawley Bottom

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Fawley Bottom can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot
  • Let building users know which areas are affected

About our expansion joint sealing in Fawley Bottom

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 jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve brittle, chalky sealant on external joints and chipped joint edges on forklift routes, across precast concrete panel joints, cladding panel joints and blockwork control joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Fawley Bottom, that means joint design, primers and backing rod as standard.

Halls, schools and small commercial buildings near places like Fawley Bottom have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

FAQs: Fawley Bottom

Is a smaller place like Fawley Bottom outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will our site in Fawley Bottom have to close for joint sealing?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

How much does the work cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

What happens if it rains on the day?

A wet joint can’t be sealed properly, so external work waits for suitable conditions. We agree a revised date with you.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long will the new sealant last?

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

Can you seal car park deck joints?

Yes. Let us know the opening hours and which levels or bays have to stay available.

Warehouse floors and decks around Fawley Bottom

At about 36 miles from central London, Fawley Bottom is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Fawley Bottom sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.

A healthcare site such as Townlands Memorial Hospital, 2.6 miles to the south of Fawley Bottom, depends on car parks, ramps and service yards whose joints take traffic all day. For floors and slabs around Fawley Bottom, the product is chosen for the traffic and the movement at each joint.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly.

Joints and surfaces we work on

  • Brickwork movement joints
  • Blockwork control joints
  • Cladding panel joints
  • Podiums and floor movement joints
  • Car park decks and ramps
  • Precast concrete panel joints

For managing agents and facilities managers

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The product specified
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits

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

Before you send an enquiry

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

  • The product your specification calls for
  • When you need the work done
  • Anything awkward about access or site hours
  • Clear photos of the problem areas

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Surface by surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

When to bring in a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
