How we handle expansion joint sealing in Winterbourne

For movement joints in Winterbourne, photographs and approximate lengths are the best start. We will come and look where photos don’t show enough before issuing a fixed quote. You can also call the office on 01277 525 020 or use the quote form to talk the joints through. Most enquiries involve torn sealant in brick or block movement joints and leaks through car park deck joints onto the level below, on precast concrete panel joints, brickwork movement joints and car park decks and ramps. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Winterbourne, that means joint design, primers and backing rod as standard.

For a site near Winterbourne, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Surface by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Why deal with it now?

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. For buildings around smaller places like Winterbourne, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • CHAS accredited contractor
  • Old sealant cut out, never sealed over
  • Work carried out by CSCS-carded applicators
  • Sealing commercial buildings since 2005

Take a look at what affects the cost or how we’re accredited.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Cracking or settlement that calls for an engineer’s assessment
  • Damaged metal nosings or cover plates over a joint

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Maintenance after handover

After handover, a little attention goes a long way:

  • Report split or peeling joint sealant early
  • Record the sealant used and the date in the O&M file
  • Plan racking layouts so feet don’t land on a joint
  • Keep scrapers and ploughs from dragging across joint sealant

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We will tell you which movement joints need doing now and which can wait.

Our process

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Winterbourne are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Confirm the product named in the specification
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Getting a fixed quote

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email us to discuss it first.

Expansion joint sealing around Winterbourne: what changes locally

Less than 3 miles from Winterbourne there are two named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Winterbourne included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Schools like Boughton-under-Blean and Dunkirk Primary School often have long brick elevations with movement joints that age quietly. For an occupier at a site such as CMA Industrial Park, 2.7 miles to the east of Winterbourne, the joints at loading doors and dock levellers typically see the hardest wear. University campuses such as University of Kent (4.5 miles east of Winterbourne) have car parks, paved walkways and building elevations with movement joints.

Winterbourne is about 4 miles south-east of Faversham, in Kent. Any commercial site in Winterbourne is covered, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places, large and small. For work in that direction, see our London page, about 48 miles away.

Common questions from Winterbourne clients

Is Winterbourne off your patch?

Not at all. Winterbourne is within our area. 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.

Can you take on a job at a hospital such as Eastbridge Hospital of St Thomas the Martyr?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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 usually need a polyurethane, and the specification has the final say.

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, because the fix differs.

What exactly is a movement joint?

They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
