Expansion joint sealing near Chartham Hatch

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When to call us in Chartham Hatch

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

It’s worth sending us details if you spot any of the following:

  • Water getting into the wall through a failed joint
  • Leaks through car park deck joints onto the level below
  • Torn sealant in brick or block movement joints
  • Chipped joint edges on forklift routes

University campuses such as University of Kent (2.7 miles north-east of Chartham Hatch) have car parks, paved walkways and building elevations with movement joints.

Our contractor checklist

About our expansion joint sealing in Chartham Hatch

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. We work on podiums and floor movement joints, brickwork movement joints and blockwork control joints, and the failures we’re asked to look at most are debris jammed in movement joints and hardened, cracked sealant on exposed facades. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chartham Hatch, that means joint design, primers and backing rod as standard.

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

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Questions about Chartham Hatch

Do you take on work at healthcare sites like Eastbridge Hospital of St Thomas the Martyr?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Does your area include sites such as CMA Industrial Park, near Chartham Hatch?

Yes. We cover Chartham Hatch and the area around it, including industrial estates, business parks and retail parks such as CMA Industrial Park. Photos and a short description are enough for a first look.

Can you seal car park deck joints?

Yes. Tell us how the car park is used and which areas must stay open.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.

Do you use silicone or polyurethane in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane, and the specification has the final say.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.

Where we work in Chartham Hatch

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Check joints after long freezing spells
  • Plan racking layouts so feet don’t land on a joint
  • Brief car park operatives to protect joint lines during winter clearance
  • Include every elevation and deck joint in periodic inspections

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

What the job involves on each surface

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, normally low-modulus, with backing rod setting the depth.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen in a colour confirmed for that product.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Chartham Hatch, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  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. Every joint is cleared of the failed seal and any grit packed into it.
  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.

Before we start on site

  • Flag any permit to work we will need
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

  • Which sealant the job calls for
  • Access and working height
  • Joint width, depth and condition
  • Whether the work must be split into stages

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