Expansion joint sealing near Heaverham

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

What happens if it’s left?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. For buildings around smaller places like Heaverham, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What you get with us

  • Constructionline member for supplier checks
  • A fixed quote before work starts
  • Joints cleaned back to sound surfaces
  • Sealing commercial buildings since 2005

Expansion joint sealing in Heaverham, done properly

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on blockwork control joints, cladding panel joints and precast concrete panel joints, and the failures we are asked to look at most are sealant pulling off the joint face and weathered movement joint sealant that no longer flexes. Whoever orders the work in Heaverham, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a site near Heaverham, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

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

Heaverham: questions and answers

Can you work at a site such as Chaucer Business Park, by Heaverham?

Yes. We cover Heaverham and the area around it, including industrial estates, business parks and retail parks such as Chaucer Business Park. A few photos and the unit address let us price the work.

Is Heaverham too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Looking after the joints

For the best life from the joints:

  • Leave barriers in place until fresh joint sealant has cured
  • Avoid parking heavy plant or pallets on joint lines
  • Brief car park operatives to protect joint lines during winter clearance
  • Put movement joints on the planned maintenance inspection round

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Resealing early limits the damage.

Traffic, movement and joints around Heaverham

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Heaverham lies roughly 20 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Large sites such as Cygnet Hospital Godden Green, 2.5 miles south-west of Heaverham, have car parks, service roads and long elevations with movement joints in brick and panels. Schools like Kemsing Primary School often have long brick elevations with movement joints that age quietly. Parks like Chaucer Business Park, 0.5 miles to the south-west of Heaverham, combine paved areas, car parks and building elevations, each with joints that move.

Heaverham is about 3 miles north-east of Sevenoaks, in Kent. Heaverham sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Kent coverage takes in 931 places. There’s a separate page for London, roughly 20 miles from Heaverham.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Heaverham may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  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

  • Flag any permit to work we will need
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Related advice

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Proprietary pre-formed expansion joint systems
  • Leaks coming from the membrane rather than the joint seal
  • Concrete or masonry repairs along the arrises

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Surfaces we seal

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

Surface by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.
