Floor joint sealing for commercial buildings in Blackboys

Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. We work on loading bays, construction joints and saw-cut induced joints, and the failures we’re asked to look at most are broken arrises where pallet trucks cross and old filler gone hard, cracked or loose. Looking for mastic applicators who cover Blackboys? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Halls, schools and small commercial buildings near places like Blackboys have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Leave it or put it right?

Some runs only need partial renewal or topping up. Where existing filler is well bonded and the gap beside it is small, a full strip-out isn’t always needed and the quote shows which approach suits each run. Halls, stores and units around places like Blackboys may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Our applicators hold CSCS cards

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

On site: what to expect

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a day for smaller units, with bigger warehouse floors programmed over several visits. Jobs in and around smaller places like Blackboys 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. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Before we start on site

  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached
  • Flag any permit to work we will need

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Access and working height
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

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.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height
  • Specification clauses that apply
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Slabs, ramps and loading bays in Blackboys

Blackboys is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Blackboys has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

Hospital campuses such as Uckfield Community Hospital (to the west of Blackboys) grow in stages, leaving movement joints wherever new blocks meet old. Schools like Blackboys Church of England Primary School often have long brick elevations with movement joints that age quietly. Business parks such as Tylers Business Park, under half a mile south-east of Blackboys, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Blackboys is about 3 miles east of Uckfield, in East Sussex. Blackboys sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 308 places in East Sussex, large and small. Brighton is covered too, some 16 miles away.

Common questions from Blackboys clients

Is Blackboys too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on work at healthcare sites like Uckfield Community Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you use semi-rigid filler or flexible sealant on floor joints?

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What do you need from us to quote?

Send details through our quote form or by email, with the traffic on each area. We then send a fixed quote with the product and phasing set out.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Surface by surface

Flexible floor sealants

Where joints move more, a flexible polyurethane floor sealant is often used. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.

Forklift and pallet-truck routes

Trucks running over open joints wear wheels and shake loads. A filled joint lets wheels roll across and protects the floor.
