Expansion joint sealing for commercial buildings in Oxford

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you’re dealing with expansion joints filled with dirt and stones and joints where the bead has lost adhesion, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Oxford, preparation and product choice get the time they need.

On busy estates around towns like Oxford, joints are resealed in stages so units keep trading: one aisle, bay or level at a time, with areas handed back as each section cures.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Joints that move: notes for Oxford

The 3 miles around Oxford 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. Oxford is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Retail centres such as Clarendon Shopping Centre, 1.1 miles to the west of Oxford, have floors, service yards and car parks with joints under constant traffic. Across sites such as Shotover Trading Estate, 1.6 miles east of Oxford, floor and movement joints can be sealed in phases so units keep working. University campuses such as Oxford Brookes University Headington Campus, under half a mile to the north-east of Oxford, have car parks, paved walkways and building elevations with movement joints.

Oxford is in Oxfordshire. Commercial clients in Oxford use us for work on movement joints, as part of our coverage of Oxfordshire. 423 places across Oxfordshire fall within our area, Oxford among them.

If you need expansion joint sealing in OX4, OX3, OX2 and OX1, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include High Street, New High Street and Radcliffe Square. With the A34 and A40 nearby, Oxford is easy to get to with materials and equipment. If your building is just outside Oxford, we cover St Clement's (1 mile west), Headington Hill (1 mile north-east), New Marston (1 mile north), Donnington (1 mile south) and St. Ebbes (1 mile west). Further afield, our area takes in Didcot (10 miles south), Bicester (11 miles north), Abingdon-on-Thames (6 miles south-west), Witney (11 miles west), Thame (11 miles east) and Wantage (14 miles south-west). Oxford ranks among the main centres of Oxfordshire, with offices, shops, schools and other public and commercial buildings, and we cover them all.

Why deal with it now?

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we will plan around it. Businesses in Oxford often have several buildings with joints of a similar age. Dealing with them together saves repeat visits.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Common questions from Oxford clients

Can you work at a site such as Templars Shopping Park, by Oxford?

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

Is hospital work, at somewhere like Warneford Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first.

Is colour matching possible?

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’ll confirm the colours available for the specified product.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What do you charge?

Each job is quoted on its own details. To get one, call 01277 525 020 or email us with a description of the work.

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Proprietary pre-formed expansion joint systems
  • Crumbling edges that would give a new bead nothing sound to grip
  • Waterproofing layers buried beneath the sealant

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

Where we work in Oxford

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Oxford can form part of a wider programme.

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.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Inspect exposed joints once the cold weather has passed
  • Keep traffic off new joints until the cure time is up
  • Keep scrapers and ploughs from dragging across joint sealant
  • Note which joints were done, when, and with what

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can call 01277 525 020 or send details through our quote form and send a picture.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Sites in a big town such as Oxford frequently have reception sign-in, inductions and permits to work. Send the site rules with your enquiry and we’ll plan to them.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • For older buildings, check the asbestos register before work
