Expansion joint sealing in Stocks Green, done properly

Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Site teams most often ask us about water getting into the wall through a failed joint and new sealant over old, now failing, across podiums and floor movement joints, car park decks and ramps and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Stocks Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Stocks Green, measurements and photos up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Floors, slabs and movement joints in Stocks Green

Stocks Green is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. At about 24 miles from central London, Stocks Green is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

Schools such as Hildenborough Church of England Primary School have movement joints in their walls and floors that are easy to overlook. For an estate such as Hollanden Park Hospital, which lies north-east of Stocks Green, the joints in ramps, decks and long building elevations all need attention over time.

Stocks Green is about 2 miles north-west of Tonbridge, in Kent. Anywhere in TN11, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Stocks Green is one of 931 places we cover in Kent. London is covered too, some 24 miles away.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Quoting for work in Stocks Green

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

  • The site’s rules and procedures
  • Which sealant the job calls for
  • Phasing around occupants
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email the details over.

Commercial clients in Stocks Green

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Stocks Green: questions and answers

Must our site in Stocks Green stop work while the joints are done?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Can you work on a hospital site such as Hollanden Park Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

What happens if it rains on the day?

A wet joint can’t be sealed properly, so external work waits for suitable conditions. We agree a revised date with you.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Stocks Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Request a quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

What we are called out for in Stocks Green

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.

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

  • Sealant peeling off one face of the joint
  • Leaks through car park deck joints onto the level below
  • Movement joints with split or torn sealant
  • Chipped joint edges on forklift routes

For estates staff at a university like University of Kent - Tonbridge, which lies south-east of Stocks Green, building and paving joints are part of the planned maintenance list.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone
