Need floor joint sealing in North Mundham?

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

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • Clear photographs of the problem areas
  • The product your specification calls for
  • Any dates the work must fit around

To get a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

About our floor joint sealing in North Mundham

Most industrial slabs are divided into panels with saw cuts and day joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. We work on forklift and pallet-truck routes, retail and showroom floors and loading bays, and what we’re called in for most is chipped and spalling edges along forklift routes and drivers complaining about joints on a route. For commercial sealant work in North Mundham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like North Mundham have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • A floor that is out of level for the racking or trucks
  • Wide or random cracking that suggests a structural issue
  • Unstable slabs moving under traffic

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

Slabs, ramps and loading bays in North Mundham

North Mundham sits close to the coast, within about 3 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. At about 55 miles from central London, North Mundham is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

University campuses such as University of Chichester (to the east of North Mundham) have car parks, paved walkways and building elevations with movement joints. For an occupier at a site such as Quarry Lane Industrial Estate, which lies north of North Mundham, the joints at loading doors and dock levellers normally see the hardest wear.

North Mundham is about 2 miles south-east of Chichester, in West Sussex. Commercial clients in North Mundham can call on us for floor joints. Our West Sussex coverage takes in 373 places, from busy centres to rural villages. For work in that direction, see our Portsmouth page, about 14 miles away.

We cover the PO20 postcode districts for floor joints. For a building on Church Road, Fletcher Place and Palmer Place or nearby, we can quote for floor joints. We also cover Runcton (1 mile east), Hunston (1 mile west), Merston (1 mile east), Donnington (1 mile west) and Lagness (2 miles south-east). Nearby towns on our patch include Bognor Regis (4 miles south-east), Selsey (6 miles south), Littlehampton (10 miles east), Rustington (11 miles east), Storrington (15 miles north-east) and Angmering (12 miles east).

Landmarks near North Mundham

Locally, jobs take us to sites close to The Spotted Cow Public House and Chichester High School For Girls and the streets around them. The nearest railway station is Chichester station, about 1.6 miles north-west of the centre. Other landmarks nearby include St Richard's Hospital (2.1 miles north) and Chichester Cathedral Treasury (1.8 miles north-west).

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes anything from a day for one loading bay to several days for a large floor, split into phases. Jobs in and around smaller places like North Mundham are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Preparing the site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings

Related advice

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

FAQs: North Mundham

Is a smaller place like North Mundham outside your area?

No. Places such as North Mundham are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Quarry Lane Industrial Estate, by North Mundham?

Yes. We cover North Mundham and the area around it, including industrial estates, business parks and retail parks such as Quarry Lane Industrial Estate. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Can the warehouse stay open while you work?

Normally only the zone we are working in has to close. Traffic returns to each zone once it has cured, then we move to the next.

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.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is it normal for joint filler to separate?

Separation typically comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

When to call us in North Mundham

Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

Typical triggers for a call:

  • Soft sealant dragged out of trafficked joints
  • Open saw cuts full of debris
  • Chipped and spalling edges along forklift routes
  • Cracked and crumbling joint fill

At places like City Business Park, 1.6 miles north-west of North Mundham, joints are sealed a section at a time so operations carry on.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Walk the main routes and inspect joint lines on a regular cycle
  • Clear packed debris from open joints regularly
  • Let us know what the floor is cleaned with
  • Plan for a top-up on newer floors

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. Cones or barriers stop the first driver cutting the corner.

Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas and keeps on top of the rest.
