Common questions from Westbourne clients

Is Westbourne too small for you to travel to?

Not at all. Westbourne is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Spire Hospital Portsmouth?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

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.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Are expansion joints and movement joints the same thing?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Expansion joint sealing in Westbourne, done properly

Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you have weathered movement joint sealant that no longer flexes and rain penetration at brick or block movement joints, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Westbourne it comes down to the same thing: the right product in a properly prepared joint.

Smaller community and commercial buildings around Westbourne have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Do you need expansion joint sealing in Westbourne?

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Things that normally lead to an enquiry:

  • Sealant peeling off one face of the joint
  • Arrises breaking up along floor joints
  • Previous reseals laid over old sealant
  • Debris jammed in movement joints

For buildings at a park such as Hambrook Business Park, which lies east of Westbourne, brick and panel movement joints are easy to forget until one leaks.

Before you book anyone

  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

What we can’t put right

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

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint
  • Concrete or masonry repairs along the arrises

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think before you book.

Surfaces we seal

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

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Westbourne, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Flag any permit to work we’ll need
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Advice

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites around Westbourne. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

How the job changes by surface

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.

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.

Joints that move: notes for Westbourne

Westbourne lies within about 2 miles of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Hospitals like Spire Hospital Portsmouth, 1.4 miles west of Westbourne, have multi-storey or surface car parks whose joints carry vehicles round the clock. In a school such as Westbourne Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Westbourne is about 3 miles east of Havant, in West Sussex. We send applicators to Westbourne for movement joints. 373 places across West Sussex fall within our area, Westbourne among them. We also cover Portsmouth, some 8 miles away.
