Need expansion joint sealing in Guilton?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work 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. Smaller jobs around Guilton can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work 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.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  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

  • Flag any permit to work we will need
  • Warn occupants and staff about the work
  • Make sure the joints can be reached

Expansion joint sealing for commercial buildings in Guilton

Width, depth and product all have to work together. 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, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on cladding panel joints, podiums and floor movement joints and car park decks and ramps, and the usual reasons a site gets in touch are rain penetration at brick or block movement joints and weathered movement joint sealant that no longer flexes. A single leaking joint is often how a building in Guilton first comes to us: we look at the rest while we’re there and tell you what we find.

For a site near Guilton, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Any access equipment needed
  • The total length or number of joints
  • Working within restricted access windows
  • How much existing material needs removing

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email the details over with what you know.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • A joint that has to be widened or re-detailed before it can work
  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Surfaces we seal

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

Questions we are asked in Guilton

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

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

Is Guilton too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you offer coloured sealant?

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

What timescale should we allow for resealing expansion joints?

Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. We confirm the timescale with the quote, including any phasing.

Are expansion joints and movement joints the same thing?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Why it’s worth doing now in Guilton

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Older rural buildings around Guilton move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Floors, slabs and movement joints in Guilton

Guilton has two named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

For a school such as Ash Cartwright and Kelsey Church of England Primary School, playground and building joints can be done in the holidays. Across sites such as Wingham Industrial Estate, 2.2 miles west of Guilton, floor and movement joints can be sealed in phases so units keep working.

When to call us in Guilton

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

If one of these sounds familiar, it’s time for a closer look:

  • Layers of sealant in a movement joint
  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Rain penetration at brick or block movement joints

Office parks like Birnham Farm Business Centre (1.6 miles south-east of Guilton) have decks, ramps and clad elevations whose joints take movement every day.
