Floor joint sealing for businesses in St Ives

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start.

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. We clear them back to clean concrete and fill them to the depth the product calls for with a flush finish.

Floor joint sealing for commercial buildings in St Ives

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. That tells us whether semi-rigid filler or flexible sealant suits each run, area by area where it needs to be. The enquiries we see most involve joint edges breaking up under truck wheels and cracked and crumbling joint fill, on retail and showroom floors, loading bays and saw-cut induced joints. Facilities teams, main contractors and managing agents in St Ives tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like St Ives have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Every job we finish is backed by a 12-month workmanship guarantee, in St Ives as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Floor joint sealing around St Ives: how the place shapes the job

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. Less than 3 miles from St Ives there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

For an estate such as St Leonards Hospital, which lies south-west of St Ives, the joints in ramps, decks and long building elevations all need attention over time. If you manage units on an estate such as Ashley Heath Industrial Estate, which lies north-west of St Ives, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Another example is Millstream Trading Estate, 1.8 miles to the east of St Ives, where floors and yards would be done in stages around the occupiers.

What affects the price in St Ives

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Which sealant the job calls for
  • Whether the work must be split into stages
  • How much existing material needs removing
  • How accessible the joints are

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email a schedule or drawings.

Commercial clients in St Ives

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in St Ives can sit alongside others in a wider programme.

Why act early in St Ives

Open joints are where dirt collects, out of reach of the floor cleaner. In shops, showrooms and clean production areas that matters for hygiene and appearance. Filled joints are far simpler to keep clean. Older rural buildings around St Ives move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Failed material removed, not covered up
  • Sealing commercial buildings since 2005

When to bring in a specialist

Some joints are best left to specialists: 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Questions about St Ives

Is a smaller place like St Ives outside your area?

Not at all: smaller places are covered as well as 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.

Is Ashley Heath Industrial Estate, near St Ives, within your area?

Yes, sites like Ashley Heath Industrial Estate are within our area, along with the rest of St Ives. Send details of the unit and the work through our quote form for a quick quote.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Why is there a gap next to the joint filler?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near St Ives need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. You get a fixed quote with the product and the phasing set out.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000
  • Tell us your opening times and when work is allowed
