About our floor joint sealing in Guston

For sites in Guston and across Kent, the process is short: send details, get a fixed quote, we seal, and the work is guaranteed. A rough length of joint, photographs of the worst areas and a site plan let us give a quick quote, or we can arrange a site visit. We work on forklift and pallet-truck routes, retail and showroom floors and joints along racking aisles, and what we are called in for most is broken arrises where pallet trucks cross and loading bay joints breaking down. For commercial sealant work in Guston, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller community and commercial buildings around Guston have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Traffic, movement and joints around Guston

Guston sits close to the coast, within about 2 miles. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. Guston is in the South East, one of the UK’s drier regions. 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.

Schools like Duke of York's Royal Military School often have long brick elevations with movement joints that age quietly. Business parks such as White Cliffs Business Park (0.9 miles west of Guston) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Guston is about 2 miles north-east of Dover, in Kent. We cover commercial sites throughout Guston, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places, from busy centres to rural villages. Sites around London have their own page, roughly 66 miles from Guston.

We also cover East Langdon (1 mile north-east), Church Whitfield (1 mile north-west), West Cliffe (1 mile east), Martin Mill (2 miles north-east) and Charlton-in-Dover (2 miles south-west) for floor joints.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Put loading bays at the top of the list
  • Mention any aggressive cleaning regime at quote stage
  • Keep grit out of unfilled joints in the meantime
  • Plan for a top-up on newer floors

Keep traffic off fresh joints until the time we give you and it pays to stick to it. In a busy building, barriers keep early traffic away.

Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • A floor that rocks at the joints, which needs a structural fix
  • Worn screed or surface finishes

If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What we seal

  • Loading bays
  • Joints along racking aisles
  • Construction joints
  • Retail and showroom floors
  • Forklift and pallet-truck routes
  • Saw-cut induced joints

When to call us in Guston

Small, hard wheels put a lot of load through a very small area. Crossing an open joint, the wheel drops and knocks the opposite arris and those knocks chip the edge apart bit by bit.

It’s worth sending us details if you spot any of the following:

  • Flexible sealant torn out by wheels
  • Broken arrises where pallet trucks cross
  • Grimy joint lines spoiling a showroom floor
  • Loading bay joints breaking down

Hospital campuses such as Buckland Hospital (to the south-west of Guston) grow in stages, leaving movement joints wherever new blocks meet old.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

Guston: questions and answers

Do you take on work at healthcare sites like Buckland Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Guston too small for you to travel to?

Not at all. Guston is within our area. 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.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Why is there a gap next to the joint filler?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We diagnose the cause before suggesting a fix.

What do you need from us to quote?

Send details through our quote form or by email, with the traffic on each area. A fixed quote follows that shows the products and zones.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For bigger or phased jobs, we will set out a timescale 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. Treat them as maintenance items and inspect them regularly.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Guston, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

What we need from you

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Make sure the joints can be reached

Getting a fixed quote

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 use the quote form to discuss it first.

Advice

Quoting for work in Guston

We price every job individually. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • How accessible the joints are
  • The total length or number of joints

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 quote and we will explain how it’s made up.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building

To get a fixed quote, call the office on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.
