About our floor joint sealing in Netley Marsh

We have been sealing commercial joints since 2005. Our CSCS-carded applicators follow your site induction and rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. If you have dock area joints that have failed first and joint edges breaking up under truck wheels, we can help, whatever the surface. A single leaking joint is often how a building in Netley Marsh first comes to us: we look at the rest while we are there and tell you what we find.

Around smaller places such as Netley Marsh, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Netley Marsh can sit alongside others in a wider programme across Hampshire.

Aftercare for building managers

To get the most from the new sealant:

  • Let us know what the floor is cleaned with
  • Sweep debris out of open joints until they can be filled
  • Record damaged joints with a photo and a location
  • Allow for topping up joints as a new slab settles

Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.

Every day an open joint stays full of grit, the edges take more punishment. Filling it ends that cycle before it becomes a repair.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Netley Marsh 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. A floor survey records every joint, its edges and what crosses it.
  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. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Before we start on site

  • Arrange parking or a loading space
  • Point out any areas we must not close
  • Tell staff and tenants when we will be in

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or ring 01277 525 020 or send photos by email to discuss it first.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Cracks across panels caused by settlement or overload
  • Spalled arrises, which need an edge repair first
  • Worn screed or surface finishes

Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

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

Common problems we fix in Netley Marsh

Floor joints collect dust, oil, curing compound and cleaning residue. If the faces aren’t taken back to clean concrete first, the new material simply lifts out.

Common reasons buildings call us in:

  • Broken arrises where pallet trucks cross
  • Trucks and loads jolting over damaged joints
  • Sealant pulled out along a truck route
  • Unfilled floor joints collecting dirt and grit

Another example is South Hampshire Industrial Park (1.6 miles north-east of Netley Marsh), where floors and yards would be done in stages around the occupiers.

What your quote should include

  • How the joint faces will be prepared and primed
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Floor joint sealing in Netley Marsh: the local picture

Netley Marsh sits close to the coast, within about 3 miles. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. The 3 miles around Netley Marsh take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

At a retail site such as Totton Shopping Centre, 1.8 miles to the east of Netley Marsh, trolleys, cages and cars run over floor and slab joints all day. For buildings at a park such as Rushington Business Park, 1.4 miles to the east of Netley Marsh, brick and panel movement joints are easy to forget until one leaks.

Different surfaces, different methods

Construction joints

Day joints vary, with or without armoured edges. We will tell you if the edges or any armouring look like they need attention before filling.

Flexible floor sealants

Polyurethane floor sealants are available in a range of colours so ask if the colour matters.

Questions about Netley Marsh

Is Netley Marsh too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is Rushington Business Park, near Netley Marsh, within your area?

Yes, sites like Rushington Business Park are within our area, along with the rest of Netley Marsh. A few photos and the unit address let us price the work.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

What happens if old sealant might contain asbestos?

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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How do we get a quote for floor joints?

A rough joint length, a few photos and a site plan let us give a quick quote. For larger floors, a site visit is often best so call the office on 01277 525 020 or send details through our quote form to set one up.
