About our floor joint sealing in Sandford St Martin

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Pricing depends on the length of joint, how worn the edges are and when we can get in, and the quote is fixed before we mobilise. We work on joints along racking aisles, retail and showroom floors and saw-cut induced joints, and the failures we’re asked to look at most are broken arrises where pallet trucks cross and soft sealant dragged out of trafficked joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Sandford St Martin it comes down to the same thing: the right product in a properly prepared joint.

Smaller community and commercial buildings around Sandford St Martin have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

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.

Where floor joints take the most wear near Sandford St Martin

Sandford St Martin is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Sandford St Martin is about 63 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.

Around Sandford St Martin, each joint gets a filler or sealant matched to what crosses it and how much it moves. On industrial estates such as Enstone Airfield Industrial Estate (1.6 miles west of Sandford St Martin), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Sandford St Martin is about 9 miles south of Banbury, in Oxfordshire. Across the OX7 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

How the job changes by surface

Flexible floor sealants

Flexible floor sealants come in several colours, and we will confirm what the specified product offers.

Forklift and pallet-truck routes

Main aisles and cross routes carry the most wheel movements and the joints on them break down first. A semi-rigid filler is common here because it supports the arrises under hard wheels.

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.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Sandford St Martin clients

Does a site in Sandford St Martin have to shut while its joints are sealed?

Normally not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Is Sandford St Martin too small for you to travel to?

No. Places such as Sandford St Martin are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

When can forklifts run over new joint filler?

Each product has its own cure time, and cold floors slow it down. Phasing is planned with that in mind.

Can the warehouse stay open while you work?

We phase it. We work aisle by aisle or zone by zone so the rest of the floor stays in use around the site hours and access windows you give us.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Are you CHAS accredited and on Constructionline?

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

Why has the filler pulled away from one side?

Separation usually comes from slab shrinkage, poor preparation or the wrong product. We diagnose the cause before suggesting a fix.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Ask drivers not to drag forks or pallets
  • Put loading bays at the top of the list
  • Keep trucks off new joints until we say they’re ready
  • Make joint checks part of your floor inspections

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. After that, a check before your busiest period keeps small repairs small.

Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Sandford St Martin may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Structural cracking in the slab
  • Uneven floors that need grinding or levelling
  • Broken concrete either side of the joint

If you’re not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Surfaces we seal

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