Expansion joint sealing in Baker's Cross

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Baker's Cross. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How we handle expansion joint sealing in Baker's Cross

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Baker's Cross. The enquiries we see most involve expansion joints filled with dirt and stones and damp inside where a wall movement joint has failed, across cladding panel joints, brickwork movement joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Baker's Cross, preparation and product choice get the time they need.

Around smaller places such as Baker's Cross, 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Avoid parking heavy plant or pallets on joint lines
  • Keep traffic off new joints until the cure time is up
  • Brief car park operatives to protect joint lines during winter clearance
  • Check joints after long freezing spells

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call the office on 01277 525 020 or email the details over with photographs.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.

Your questions answered

Is Hartley Dyke Business Centre, near Baker's Cross, within your area?

Yes, sites like Hartley Dyke Business Centre are within our area, along with the rest of Baker's Cross. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Benenden Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover Baker's Cross?

Yes. We cover Baker's Cross, and you can give us a call on 01277 525 020 or email a schedule or drawings to get started.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably and the way they’re sealed is similar.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building around Baker's Cross, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email the details over.

Cost factors for movement joints

A fixed quote reflects the actual work. It takes account of:

  • The size and state of each joint
  • Whether the work must be split into stages
  • Location, for remote and island sites
  • The site’s rules and procedures

No two sites price the same: 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

We can often quote from photographs and a few details. It helps to include:

  • The product your specification calls for
  • A wide shot and a close-up of the area
  • The site address and postcode
  • What the building is and how it’s used

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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

Joints that move: notes for Baker's Cross

Less than 3 miles from Baker's Cross there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Baker's Cross lies roughly 39 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

In a school such as Cranbrook School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Across sites such as Hawkhurst Station Business Park, 2.7 miles south-west of Baker's Cross, floor and movement joints can be sealed in phases so units keep working. For an estate such as Benenden Hospital, which lies east of Baker's Cross, the joints in ramps, decks and long building elevations all need attention over time.

Baker's Cross is about 9 miles south-east of Paddock Wood, in Kent. Baker's Cross sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Kent coverage takes in 931 places. Brighton is covered too, some 34 miles away.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Waterproofing layers buried beneath the sealant
  • Crumbling edges that would give a new bead nothing sound to grip
  • Damaged metal nosings or cover plates over a joint

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