Floor joint sealing for Marlow sites

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. 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.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

About our floor joint sealing in Marlow

Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so we will tell you if the joint edges need repairing first and explain how it affects the programme. We work on saw-cut induced joints, joints along racking aisles and construction joints, and what we are called in for most is unfilled floor joints collecting dirt and grit and joint edges breaking up under truck wheels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Marlow, preparation and product choice get the time they need.

In Marlow, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How the quote is worked out

We price every job individually. The main factors are:

  • Access and working height
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • When you need the work done
  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.

Common questions from Marlow clients

Does a site in Marlow have to shut while its joints are sealed?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

Will you take on work at estates like Globe Business Park, close to Marlow?

Yes. We cover Marlow and the area around it, including industrial estates, business parks and retail parks such as Globe Business Park. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

Do you use semi-rigid filler or flexible sealant on floor joints?

The answer comes from the traffic and the joint’s movement. Trafficked joints on truck routes normally need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is the floor joint work guaranteed?

A 12-month guarantee covers the work we do. It covers our workmanship, not later slab movement or damage from impacts.

How the job changes by surface

Construction joints

Day joints on busy routes are prone to edge damage. Movement and traffic are both checked before we decide what goes in.

Saw-cut induced joints

A sawn joint left open soon packs with debris and chips at the edges. Filled in good time, they stay narrow and neat.

When something else is needed

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

  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Cracks across panels caused by settlement or overload
  • A floor that is out of level for the racking or trucks

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Do you need floor joint sealing in Marlow?

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

Any of the following is a good reason to get the joints checked over:

  • Failing joints at loading bays and dock doors
  • A gap opening alongside old joint filler
  • Sealant pulled out along a truck route
  • Brittle joint filler breaking up

In a school such as Holy Trinity Church of England (Aided) School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a town like Marlow, we try to group jobs for the same client into one visit. Give us your access times and we’ll fit the work in.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Share the asbestos register for older buildings
  • Agree which areas must stay open
  • Move anything stored against the joints
