Expansion joint sealing for Colt's Hill sites

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

Expansion joint sealing in Colt's Hill

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. If you have brittle, chalky sealant on external joints and water dripping through deck or ramp joints, we can help, on podiums and floor movement joints, blockwork control joints and cladding panel joints alike. Facilities teams, main contractors and managing agents in Colt's Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Slabs, ramps and loading bays in Colt's Hill

At about 30 miles from central London, Colt's Hill 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. Colt's Hill has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Across sites such as Forstal Business Park, which lies north-east of Colt's Hill, floor and movement joints can be sealed in phases so units keep working. For estates staff at a university like University of Kent - Tonbridge, 4.1 miles west of Colt's Hill, building and paving joints are part of the planned maintenance list. Hospitals like Tunbridge Wells Hospital at Pembury (2.7 miles south-west of Colt's Hill) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Colt's Hill is about 4 miles south-east of Tonbridge, in Kent. Anywhere in TN12, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Colt's Hill is one of 931 places we cover in Kent. London is covered too, around 30 miles from Colt's Hill.

Questions about Colt's Hill

Is Colt's Hill too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you take on work at estates like Eldon Way Industrial Estate, close to Colt's Hill?

Yes, sites like Eldon Way Industrial Estate are within our area, along with the rest of Colt's Hill. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work so external dates keep some flexibility.

What causes movement joint sealant to fail?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.

Will your applicators have CSCS cards?

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

Can a joint be sealed if the edges are broken?

A bond is only as strong as the material behind it, so we’ll tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

How the job changes by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal

If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

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

Why it’s worth doing now in Colt's Hill

Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme. Urgent joints now, the rest later, is often the sensible plan. One visit to deal with every failing joint makes more sense than several trips to a place like Colt's Hill. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Why clients in Colt's Hill choose us

  • Standard and matched colours in many product ranges
  • Fully insured
  • A Constructionline member, so easy to vet
  • Colours chosen to suit frames, cladding or finishes where possible

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Jobs in and around smaller places like Colt's Hill are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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.

Before we start on site

  • Arrange parking or a loading space
  • Make sure the joints can be reached
  • Tell staff and tenants when we’ll be in
