Expansion joint sealing in Oval

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we can’t put right

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

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Concrete or masonry repairs along the arrises
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Surfaces we seal

  • Brickwork movement joints
  • Cladding panel joints
  • Blockwork control joints
  • Car park decks and ramps
  • Precast concrete panel joints
  • Podiums and floor movement joints

Expansion joint sealing in Oval, done properly

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. Site teams most often ask us about expansion joints split through the centre of the bead and sealant pulling off the joint face, on blockwork control joints, precast concrete panel joints and brickwork movement joints. Looking for mastic applicators who cover Oval? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Oval means thinking about access, loading times and the ULEZ as well as the joints.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Building owners, agents and FMs in Oval

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Oval can sit alongside others in a wider programme.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

Cost factors for movement joints

Your fixed quote is built from the real scope. It allows for:

  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • Joint width, depth and condition

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 fixed quote and we will explain how it’s made up.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Specification clauses that apply
  • Whether the building will be occupied during the work

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email us.

How the job changes by surface

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Warehouse floors and decks around Oval

The 3 miles around Oval 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. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.

Retail centres such as Southernwood Retail Park (2 miles east of Oval) have floors, service yards and car parks with joints under constant traffic. A healthcare site such as Gordon Hospital, 1 mile north-west of Oval, depends on car parks, ramps and service yards whose joints take traffic all day. For estates staff at a university like University of the Arts London, 1.4 miles west of Oval, building and paving joints are part of the planned maintenance list.

Oval is about 1 mile north of Stockwell, in Greater London. Looking for expansion joint sealing in Oval? We can help, as we do across Greater London. Our Greater London coverage takes in 764 places, from busy centres to rural villages.

If you need expansion joint sealing in SW8, SW9 and SW1P, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Close to Oval, our area also takes in Kennington (1 mile north), South Lambeth (1 mile south-west), Little Portugal (1 mile south), North Brixton (1 mile south-east) and Vauxhall (1 mile north).

Your questions answered

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.

Will you take on work at estates like Handel Business Centre, close to Oval?

Yes, sites like Handel Business Centre are within our area, along with the rest of Oval. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Why do our movement joints keep failing?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first, because the fix differs.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

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 without shutting the whole car park. Tell us what has to stay open and we will plan around it. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • CSCS-carded applicators
  • One contact handling all your sites
  • Standard and matched colours in many product ranges
  • Work to your specification and the manufacturer’s guidance

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For a job in Oval, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
