You can also give us a call on 01277 525 020 or email us to talk the joints through.

Around smaller places such as Upper Upnor, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we’ll come back to it.

How the job changes by surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. For a building around Upper Upnor, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers
  • Distance, for remote addresses

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule
  • The product your specification calls for
  • Any dates the work must fit around

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or send photos by email.

Do you need expansion joint sealing in Upper Upnor?

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Clients normally get in touch after noticing something like this:

  • Previous reseals laid over old sealant
  • Weathered movement joint sealant that no longer flexes
  • Chipped joint edges on forklift routes
  • Joints where the bead has lost adhesion

Another example is Gun Lane Business Centre, 1.4 miles south-west of Upper Upnor, where floors and yards would be done in stages around the occupiers.

Before you book anyone

  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Expansion joint sealing around Upper Upnor: what changes locally

With the shore within about 2 miles, Upper Upnor counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. 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 winter de-icing salt on car parks and ramps works into any open joint.

In a school such as Wainscott Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For estates staff at a university like University of Kent - Medway Campus (0.9 miles south-east of Upper Upnor), building and paving joints are part of the planned maintenance list.

Upper Upnor is about 2 miles north-east of Rochester, in Medway.

General trades versus a specialist

Certain joints really need a specialist: for instance 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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we’re asked in Upper Upnor

Is a smaller place like Upper Upnor outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Castle View Business Centre, near Upper Upnor?

Yes. Our area takes in Upper Upnor and its surroundings, with estates and business parks such as Castle View Business Centre included. Photos and a short description are enough for a first look.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Movement on a scale no sealant is meant to absorb
  • Damaged metal nosings or cover plates over a joint
  • Crumbling edges that would give a new bead nothing sound to grip

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