Expansion joint sealing in Priestwood

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on precast concrete panel joints, podiums and floor movement joints and cladding panel joints, and the failures we’re asked to look at most are debris jammed in movement joints and brittle, chalky sealant on external joints. For commercial sealant work in Priestwood, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a site near Priestwood, 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 are clear about what is covered before work starts.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Priestwood are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints

Common questions from Priestwood clients

Does your area include sites such as Bowes Industrial Centre, near Priestwood?

Yes. Our area takes in Priestwood and its surroundings, with estates and business parks such as Bowes Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.

Do we have to stop operations in Priestwood while the joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

How much does the work cost?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

Why do our movement joints keep failing?

Usually the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Why act early in Priestwood

A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. For buildings around smaller places like Priestwood, 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.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What you get with us

  • Workmanship guaranteed for 12 months
  • One number for every site we cover
  • Specification-led, product-correct work
  • Fully insured

Take a look at our cost guide and our accreditations.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.

Joints and surfaces we work on

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

How the job changes by surface

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.

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.

Slabs, ramps and loading bays in Priestwood

Priestwood is about 22 miles from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Priestwood is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

In a school such as Meopham School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Priestwood is about 5 miles south of Gravesend, in Kent. Commercial clients in Priestwood use us for work on movement joints, as part of our coverage of Kent. Our Kent coverage takes in 931 places. London is covered too, some 22 miles away.

If you need expansion joint sealing in DA13, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

We also cover Priestwood Green (1 mile south-west), Harvel (1 mile south), South Street (1 mile west), Foxendown (1 mile north) and Culverstone Green (1 mile south-west).

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

What we’re called out for in Priestwood

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

If one of these sounds familiar, it’s time for a closer look:

  • Car park joints leaking onto vehicles below
  • Sealant pulling off the joint face
  • Joints packed with grit and debris
  • New sealant over old, now failing

Warehouse floors on estates like Bowes Industrial Centre (to the north-west of Priestwood) carry pallet trucks and forklifts over every saw-cut joint.

Comparing quotes

  • How the joint faces will be prepared and primed
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • Is the sealant right for the movement and the substrate?
