How we handle expansion joint sealing in Gillingham

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. We work on podiums and floor movement joints, blockwork control joints and brickwork movement joints, and what we’re called in for most is brittle, chalky sealant on external joints and torn sealant in brick or block movement joints. Looking for mastic applicators who cover Gillingham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Large places such as Gillingham typically have industrial estates and business parks with warehouse and trade-counter floors. Their floor joints take forklifts, pallet trucks and cars every day, and the right filler or sealant depends on the traffic and the movement.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Gillingham clients

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

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you cover business parks and estates near Gillingham, such as Gillingham Business Park?

Yes. Estates, retail parks and business parks around Gillingham, Gillingham Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you work on car park ramps and decks?

Yes, we do. These joints take wheels, salt and water, so product choice matters, and we will tell you if any edges need repairing first.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

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.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Include photographs or drawings if you have them.

Cost factors for movement joints

The price varies from site to site. Expect it to depend on:

  • Backing rod, priming and other preparation
  • How accessible the joints are
  • Location, for remote and island sites
  • Which sealant the job calls for

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • The type of building and who uses it
  • Your programme or deadline
  • The product your specification calls for
  • Photos of the joints, close up and from further back

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or send details through our quote form.

Different surfaces, different methods

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, usually low-modulus laid over backing rod at the correct depth.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Town-centre jobs in Gillingham can mean limited parking and loading, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints

Floors, slabs and movement joints in Gillingham

Gillingham is within about 2 miles of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Gillingham 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.

Hospital campuses such as Medway Maritime Hospital, 1.6 miles to the west of Gillingham, grow in stages, leaving movement joints wherever new blocks meet old. Phasing is what makes joint work possible on busy sites such as Beechings Way Industrial Centre (0.6 miles north of Gillingham): one bay, aisle or car park row at a time. Business parks such as Gillingham Business Park, 0.5 miles to the south of Gillingham, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Gillingham is about 30 miles east of London, in Medway. Looking for expansion joint sealing in Gillingham? We can help. We work across 54 places in Medway, large and small. There’s a separate page for London, roughly 30 miles from Gillingham.

We take on movement joints across the ME8, ME7, ME4 and ME5 postcode area, for business premises of every kind. For a building on Leeds Square, London Road and Dorset Square or nearby, send details and we’ll quote for movement joints. Gillingham sits on or close to the A2 and A231. Close to Gillingham, our area also takes in Twydall (1 mile east), Lower Twydall (1 mile north-east), Grange (1 mile north), Darland (1 mile south-west) and Hale (1 mile south-west). Bigger towns within reach include Rochester (4 miles west), Strood (4 miles west), Lordswood (3 miles south-west), Hoo St Werburgh (4 miles north), Rochester Riverside (3 miles north-west) and Frindsbury (4 miles north-west).

Commercial clients in Gillingham

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Why it’s worth doing now in Gillingham

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Businesses in Gillingham often have several buildings with joints of a similar age. Renewing them in one programme saves time later.

Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
