Expansion joint sealing in Newington

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the job changes by surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.

Expansion joint sealing in Newington

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and the failures we’re asked to look at most are sealant peeling off one face of the joint and arrises breaking up along floor joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Newington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Newington are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Work we carry out in Oxfordshire comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send photos by email and we’ll arrange a return visit.

Where floor joints take the most wear near Newington

Newington lies roughly 45 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. 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.

Office parks like Monument Business Park, 2.3 miles east of Newington, have decks, ramps and clad elevations whose joints take movement every day. Hospitals like Littlemore Hospital, 5.7 miles to the north-west of Newington, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Newington is about 7 miles north-east of Didcot, in Oxfordshire. Businesses, contractors and managing agents in Newington use us for work on movement joints, as part of our coverage of Oxfordshire.

Why act early in Newington

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Converted and older buildings near places like Newington tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Read what affects the cost and our accreditations.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Look over external and deck joints after a hard winter
  • Record the sealant used and the date in the O&M file
  • Keep stones and debris out of open joint lines
  • Leave barriers in place until fresh joint sealant has cured

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, give us a call on 01277 525 020 or email a schedule or drawings with photos.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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 where general trades tend to cut corners.

Cost factors for movement joints

Quotes vary with the job. It mainly depends on:

  • Distance, for remote addresses
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • The product your specification calls for
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Common questions from Newington clients

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

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Newington off your patch?

Not at all. Newington is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

How long will the joint resealing take?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote along with the phasing plan.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. If others near Newington need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints
  • Confirm the product named in the specification
