Need expansion joint sealing in Puddledock?

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

General trades versus a specialist

Certain joints really need a specialist: 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.

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

Expansion joint sealing in Puddledock, done properly

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. If you are dealing with hardened, cracked sealant on exposed facades and new sealant over old, now failing, we can put it right, on blockwork control joints, brickwork movement joints and podiums and floor movement joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Puddledock is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller community and commercial buildings around Puddledock have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Work we carry out comes with a 12-month guarantee. 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

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability.

Building owners, agents and FMs in Puddledock

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Puddledock can form part of a wider programme.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a building around Puddledock, 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. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

Advice

Puddledock: questions and answers

Is a smaller place like Puddledock outside your area?

No. Places such as Puddledock are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work at a site such as Pembroke Business Centre, by Puddledock?

Yes. Estates, retail parks and business parks around Puddledock, Pembroke Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane, and the specification has the final say.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Expansion joint sealing around Puddledock: what changes locally

At least three named trading, business or retail sites lie within about 3 miles of Puddledock. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Rainfall across the South East, Puddledock included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Large sites such as West Hill Hospital (to the north-east of Puddledock) have car parks, service roads and long elevations with movement joints in brick and panels. Campuses like University of Greenwich (4.3 miles east of Puddledock) mix old and new buildings, with movement joints wherever they meet. At places like Park Road Industrial Estate, which lies south of Puddledock, joints are sealed a section at a time so operations carry on.

Puddledock is about 1 mile north of Swanley, in Kent. If you are looking for expansion joint sealing in Puddledock, we can help. Puddledock is one of 931 places we cover in Kent. For work in that direction, see our London page.

Cost factors for movement joints

We price every job individually. The things that drive the figure:

  • Phasing around occupants
  • Site requirements such as inductions and permits
  • Location, for remote and island sites
  • How much there is to seal

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • Specification clauses that apply

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

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A joint that has to be widened or re-detailed before it can work
  • Concrete or masonry repairs along the arrises
  • Movement on a scale no sealant is meant to absorb

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