Expansion joint sealing for commercial buildings in Adgestone

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. Most enquiries involve car park joints leaking onto vehicles below and weathered movement joint sealant that no longer flexes, across car park decks and ramps, precast concrete panel joints and podiums and floor movement joints. Looking for mastic applicators who cover Adgestone? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Jobs around smaller places like Adgestone are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Adgestone need work, visits can be combined. You will have a fixed quote before work starts.

  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, 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.

What we need from you

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs

How the job changes by surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows
  • Access and working height
  • Induction, permit and paperwork requirements

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Clear photos of the problem areas
  • Any dates the work must fit around
  • The postcode of the building
  • Any specification or named product

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send photos by email.

Do you need expansion joint sealing in Adgestone?

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way unless width and product are reviewed.

What tends to prompt an enquiry:

  • Water getting into the wall through a failed joint
  • Previous reseals laid over old sealant
  • Movement joints with split or torn sealant
  • Weathered movement joint sealant that no longer flexes

Another example is Langbridge Business Centre (2.2 miles west of Adgestone), where floors and yards would be done in stages around the occupiers.

Before you book anyone

  • How joint depth will be controlled
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Warehouse floors and decks around Adgestone

Adgestone lies within about 2 miles of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. The 3 miles around Adgestone take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

In a school such as Brading Church of England Controlled Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospitals like Arthur Webster Memorial Hospital for Children, 2.7 miles south of Adgestone, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Adgestone: questions and answers

Is Adgestone off your patch?

No. Places such as Adgestone are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can being near the sea in Adgestone affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Why has the sealant in our expansion joints split?

Typically the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.

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. Where it’s visible beforehand, we’ll say so when we quote.

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 we plan with the forecast in mind.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What do you charge?

Every job gets its own fixed quote. To get one, call 01277 525 020 or send details through our quote form.

When something else is needed

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

  • Crumbling edges that would give a new bead nothing sound to grip
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.
