Floor joint sealing across Streat

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Floor joint sealing in Streat

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. We work on construction joints, retail and showroom floors and joints along racking aisles, and what we’re called in for most is filler that has parted from one face and saw-cut joints left open and packed with grit. Looking for mastic applicators who cover Streat? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For a site near Streat, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions we are asked in Streat

Will you take on work at estates like Ditchling Common Business Park, close to Streat?

Yes. We cover Streat and the area around it, including industrial estates, business parks and retail parks such as Ditchling Common Business Park. Photos and a short description are enough for a first look.

Is a smaller place like Streat outside your area?

Not at all. Streat is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is normally right, and movement joints or perimeters need something flexible. The quote sets out what goes where.

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

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Why has the filler pulled away from one side?

Separation normally comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Where floor joints take the most wear near Streat

Streat lies roughly 40 miles out from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Less than 3 miles from Streat there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Hospitals like Lewes Victoria Hospital, 4.5 miles south-east of Streat, have multi-storey or surface car parks whose joints carry vehicles round the clock. Another example is Mid Sussex Business Park, 2.1 miles to the north of Streat, where floors and yards would be done in stages around the occupiers.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or more, depending on the metres of joint and how many zones the floor is split into, and we clear our waste as we work. Smaller jobs around Streat can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

If you look after buildings for someone else, 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.

When to call us in Streat

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass so the arrises break sooner.

These are often picked up first by site or facilities staff:

  • Loading bay joints breaking down
  • Broken arrises where pallet trucks cross
  • Joint fill separating from the concrete
  • Open saw cuts full of debris

In a school such as Plumpton Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?
  • How they handle RAMS and site documents
  • How joint depth will be controlled

Our contractor checklist

Should maintenance staff do it?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

Saw-cut induced joints

Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They start narrow and widen as the concrete dries so trafficked runs need a filler that holds the arrises.

Retail and showroom floors

In retail, joints take trolleys, castors and cleaning machines rather than forklifts. We pick a filler or sealant to suit and the appearance is part of the brief.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • A failing floor coating, which is a flooring contractor’s job
  • A floor that rocks at the joints, which needs a structural fix
  • Broken concrete either side of the joint

If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
