Expansion joint sealing for Ewell sites

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

Expansion joint sealing in Ewell, done properly

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you’re dealing with damp inside where a wall movement joint has failed and chipped joint edges on forklift routes, we can help, whatever the surface. A single leaking joint is often how a building in Ewell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Towns such as Ewell usually have an industrial estate or a few business units, with warehouse floors and loading areas. Small units are often busy, so joints are done at times that suit the occupier.

A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we will arrange a return visit.

When to call us in Ewell

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

What tends to prompt an enquiry:

  • Previous reseals laid over old sealant
  • Leaks through car park deck joints onto the level below
  • Sealant peeling off one face of the joint
  • Damp inside where a wall movement joint has failed

At a retail site such as The Ashley Centre, 1.6 miles to the south of Ewell, trolleys, cages and cars run over floor and slab joints all day.

Questions to ask before you book

  • How the existing material will be dealt with
  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. In a town such as Ewell, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • Warn occupants and staff about the work

How the quote is worked out

To price the job, we consider:

  • The site’s rules and procedures
  • Any access equipment needed
  • The product specified
  • Whether the work must be split into stages

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • The asbestos register, for older buildings
  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • When you need the work done

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or send details through our quote form to discuss it first.

Questions about Ewell

Must our site in Ewell stop work while the joints are done?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Is Longmead Industrial Estate, near Ewell, within your area?

Yes. Estates, retail parks and business parks around Ewell, Longmead Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

What sealant do you use in movement joints?

Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.

What do you charge?

Each job is quoted on its own details. For yours, call 01277 525 020 or email a schedule or drawings with a description of the work.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Joints that move: notes for Ewell

Ewell is about 12 miles from central London. The roads out of London are lined with trade parks and distribution sheds. The 3 miles around Ewell take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Campuses like University for the Creative Arts, 1.7 miles south of Ewell, mix old and new buildings, with movement joints wherever they meet. A healthcare site such as St. Ebba's Hospital (to the west of Ewell) depends on car parks, ramps and service yards whose joints take traffic all day.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Damaged metal nosings or cover plates over a joint
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Changing the joint layout or spacing of a structure

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.

Surfaces we seal

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

Different surfaces, different methods

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
