Expansion joint sealing across Rochester

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Honest limits

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

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Cracking or settlement that calls for an engineer’s assessment
  • Broken or spalled joint edges, which need repairing before any sealant goes in

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

Joints and surfaces we work on

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

Expansion joint sealing in Rochester

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. We will tell you if the edges need repairing before sealing. We work on brickwork movement joints, precast concrete panel joints and cladding panel joints, and the failures we are asked to look at most are sealant pulling off the joint face and chipped joint edges on forklift routes. Looking for mastic applicators who cover Rochester? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

In Rochester, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. A split or hardened joint lets rain into the wall, and it can no longer take up the movement.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Cost factors for movement joints

What shapes the price:

  • The product specified
  • How accessible the joints are
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or use the quote form.

Where floor joints take the most wear near Rochester

With the shore within about 3 miles, Rochester counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Rochester sits in one of the drier corners of the country, the South East. 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.

Retail sites such as Strood Retail Park, under half a mile to the north-west of Rochester, have car park, service yard and shop floor joints under constant traffic. Across sites such as Castle View Business Centre (less than half a mile east of Rochester), floor and movement joints can be sealed in phases so units keep working.

Rochester is about 27 miles east of London, in Medway. Across the ME2 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Medway, 54 places are covered, Rochester among them. There’s a separate page for London, about 27 miles away.

Anyone looking for expansion joint sealing in ME2, ME1, ME3 and ME4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on High Street, Gundolph Square and Station Road. You’ll find Rochester on or near the A2 and A226. If your building is just outside Rochester, we cover Strood (1 mile west), Borstal (1 mile south-west), Cuxton (2 miles south-west), Lower Bush (3 miles west) and North Halling (3 miles south-west). Further afield, our area takes in Gillingham (4 miles east), Chatham (3 miles south-east), Rainham (5 miles south-east), Park Wood (5 miles south-east), Lordswood (4 miles south-east) and Twydall (4 miles east). Among the larger centres in Medway is Rochester, and its commercial and public buildings are all within our area.

Local landmarks in Rochester

Also close by are Temple School (1.2 miles north) and Royal Crown Hotel (less than half a mile east). Rochester has its own railway station: Rochester station.

Do you need expansion joint sealing in Rochester?

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Clients usually get in touch after noticing something like this:

  • Water dripping through deck or ramp joints
  • Chipped joint edges on forklift routes
  • Previous reseals laid over old sealant
  • Weathered movement joint sealant that no longer flexes

A campus such as University for the Creative Arts - Rochester (to the south-east of Rochester) has long runs of movement joint in its buildings, decks and paving.

How to choose a sealant contractor

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Parking and loading for town-centre jobs in Rochester are worth mentioning when you send details. Industrial and business units typically have yard or car park space.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

Advice

Questions about Rochester

Do you cover business parks and estates near Rochester, such as Strood Retail Park?

Yes, sites like Strood Retail Park are within our area, along with the rest of Rochester. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Our building in Rochester is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can you seal joints in cold or wet weather?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.

Can you seal car park deck joints?

Yes. We use a sealant designed for wheel loads and the expected movement.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

Looking after the joints

Once the work is signed off, these steps help:

  • Inspect exposed joints once the cold weather has passed
  • Keep traffic off new joints until the cure time is up
  • Keep racking legs and heavy point loads off floor joints
  • Raise snow-clearing blades over deck joints where possible

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.

Surface by surface

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, normally low-modulus.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.
