Floor joint sealing across Warsash

Floor joint sealing in Warsash

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them so the rest of the operation keeps going. If you are dealing with drivers complaining about joints on a route and joint edges breaking up under truck wheels, we can put it right, whatever the surface. Looking for mastic applicators who cover Warsash? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around Warsash, most floor and movement joint jobs are single buildings or yards. That way the right materials come on the day and the job is done in one visit where possible.

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.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Phasing around occupants
  • The site’s rules and procedures
  • Travel to remote or island sites
  • Access and working height

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or use the quote form.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What the job involves on each surface

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filling them early keeps them tidy and protects the edges.

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start so nothing has to move unexpectedly.

Your questions answered

Would you work within a site like Fareham Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Does your area include sites such as Park Gate Business Centre, near Warsash?

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

Are you fully insured?

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

What guarantee do you give on joint filling?

A 12-month guarantee covers the work we do. It applies to our workmanship rather than structural movement or accidental damage.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Floor joint sealing around Warsash: what changes locally

The sea is no more than about 1 mile from Warsash. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Warsash lies roughly 68 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

Schools like Hook-With-Warsash Church of England Academy often have long brick elevations with movement joints that age quietly. Another example is Ensign Way Business Park (1.7 miles west of Warsash), where floors and yards would be done in stages around the occupiers.

Signs you need floor joint sealing in Warsash

Loading bay joints are exposed to wind, wet tyres and bigger temperature swings, as well as the tightest turning loads. That is usually where joint failure starts.

Typical triggers for a call:

  • Chipped and spalling edges along forklift routes
  • Brittle joint filler breaking up
  • Unfilled floor joints collecting dirt and grit
  • Sealant pulled out along a truck route

Hospitals like Fareham Community Hospital, 1.1 miles north-east of Warsash, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants

Choosing a commercial sealant contractor

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For a site in Warsash, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. You get a fixed quote with the product and the phasing set out.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Arrange parking or a loading space
  • Tell staff and tenants when we will be in

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
