How we handle floor joint sealing in Summertown

Floor joint sealing for us covers warehouse aisles, loading bays, production halls, retail floors and showroom slabs. Each job is priced from the metres of joint, their condition and the access windows we get, and the quote is fixed before we mobilise. The enquiries we see most involve brittle joint filler breaking up and joint edges breaking up under truck wheels, across forklift and pallet-truck routes, loading bays and saw-cut induced joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Summertown, preparation and product choice get the time they need.

Rural business units around smaller places such as Summertown often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

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

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Work in places the size of Summertown is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. You get a fixed quote with the product and the phasing set out.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need
  • Clear stock, furniture or equipment away from the joints

Advice

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

How the quote is worked out

We price every job individually. The main factors are:

  • The size and state of each joint
  • Quantities, in metres or numbers
  • Any access equipment needed
  • Working within restricted access windows

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Any specification or named product
  • The site address and postcode

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.

Your questions answered

Is Summertown too far out for you?

Not at all. Summertown is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Would you work within a site like John Radcliffe Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How long before trucks can use the joints?

Each product has its own cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Is it normal for joint filler to separate?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We diagnose the cause before suggesting a fix.

How the job changes by surface

Isolation joints at walls and columns

Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We include them in the survey.

Construction joints

Where a day joint crosses a truck route, its edges take heavy punishment. We look at how much they are moving before choosing the treatment.

Joints that move: notes for Summertown

The 3 miles around Summertown 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. Rainfall across the South East, Summertown included, is lower than in many parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Campuses like University of Oxford, 1.6 miles to the south of Summertown, mix old and new buildings, with movement joints wherever they meet. Business parks such as Jordan Hill Business Park (1.1 miles north of Summertown) have car parks, paved areas and long brick and panel elevations, all with movement joints. For a centre such as Clarendon Shopping Centre, 1.8 miles to the south of Summertown, the service yard and car park joints typically need attention first.

Summertown is about 2 miles north-west of Oxford, in Oxfordshire. Commercial clients in Summertown use us for work on floor joints. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages.

Business premises anywhere in OX2 and OX3 are within our area. We cover commercial and managed buildings on Islip Road, Hobson Road and Hernes Road and the roads nearby.

Open spaces near Summertown include Hook Meadow and The Trap Grounds and Headington Hill.

General trades versus a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Wide or random cracking that suggests a structural issue
  • Slab panels that rock or move under load
  • Damaged or worn floor coatings and screeds

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