How we handle floor joint sealing in Lower Sheering

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and we are CHAS accredited and a Constructionline member holding public liability insurance. Completed joints come with a 12-month guarantee on our workmanship. Site teams most often ask us about a gap opening alongside old joint filler and old filler gone hard, cracked or loose, across retail and showroom floors, construction joints and joints along racking aisles. Most enquiries from Lower Sheering start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

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

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Structural cracking in the slab
  • Broken concrete either side of the joint
  • A failing floor coating, which is a flooring contractor’s job

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

  • Construction joints
  • Saw-cut induced joints
  • Joints along racking aisles
  • Retail and showroom floors
  • Forklift and pallet-truck routes
  • Loading bays

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Why deal with it now?

A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints before or alongside any coating work. Converted and older buildings near places like Lower Sheering tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Lower Sheering need work, visits can be combined. A fixed quote is given before anything starts.

  1. A floor survey records every joint, its edges and what crosses it.
  2. The treatment and the zones are set out in a fixed quote.
  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.

Getting the site ready

  • Send your site hours and access windows
  • Let building users know which areas are affected
  • Point out any areas we must not close

FAQs: Lower Sheering

Can you take on a job at a hospital such as Rivers Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Allen House Business Centre, by Lower Sheering?

Yes. Our area takes in Lower Sheering and its surroundings, with estates and business parks such as Allen House Business Centre included. Photos and a short description are enough for a first look.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

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

There isn’t one answer for a whole floor. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. The quote sets out what goes where.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Are you CHAS accredited and on Constructionline?

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

Do you need floor joint sealing in Lower Sheering?

Older fills harden, shrink and crack with age especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.

Clients normally get in touch after noticing something like this:

  • A rough ride across broken joints
  • Soft sealant dragged out of trafficked joints
  • Chipped and spalling edges along forklift routes
  • Old filler gone hard, cracked or loose

Across sites such as Clarklands Industrial Estate, which lies north-west of Lower Sheering, floor and movement joints can be sealed in phases so units keep working.

What your quote should include

  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • Can the work be phased to keep areas open?
