How we handle expansion joint sealing in Roe End

For movement joints in Roe End, photographs and approximate lengths are the best start. We will come and look where photos don’t show enough. You can also ring 01277 525 020 or email us to talk the joints through. The enquiries we see most involve arrises breaking up along floor joints and damp inside where a wall movement joint has failed, across brickwork movement joints, precast concrete panel joints and car park decks and ramps. Looking for mastic applicators who cover Roe End? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places like Roe End, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The site’s rules and procedures
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • How accessible the joints are

Pricing movement joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • Access details, including height
  • Drawings or a marked-up plan, if available
  • The product your specification calls for

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Put movement joints on the planned maintenance inspection round
  • Keep scrapers and ploughs from dragging across joint sealant
  • Avoid parking heavy plant or pallets on joint lines
  • Keep product details with the building records for the next reseal

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Roe End can be grouped with others nearby. A fixed quote is given before anything 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 tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Before we start on site

  • Confirm the product named in the specification
  • Arrange parking or a loading space
  • Tell staff and tenants when we will be in

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Joints that move: notes for Roe End

Roe End is about 28 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift. Roe End is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

A campus such as University Of Bedfordshire (to the north-east of Roe End) has long runs of movement joint in its buildings, decks and paving. Business parks such as Cotswold Business Park, 1.9 miles north of Roe End, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Why it’s worth doing now in Roe End

A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. Converted and older buildings near places like Roe End tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • Health and safety: CHAS accredited
  • Clear, fixed quotes
  • Matching to RAL references, product permitting
  • Old sealant cut out, never sealed over

See our cost guide or our accreditations.

When to call us in Roe End

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

It’s worth sending us details if you spot any of the following:

  • Chipped joint edges on forklift routes
  • Water dripping through deck or ramp joints
  • Expansion joints split through the centre of the bead
  • Damp inside where a wall movement joint has failed

Another example is Eden Brae Business Park, 2.2 miles to the north of Roe End, where floors and yards would be done in stages around the occupiers.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Their approach to joint depth and backing
  • Who will actually carry out the work

How to choose a sealant contractor

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Proprietary pre-formed expansion joint systems
  • Cracking or settlement that calls for an engineer’s assessment
  • Leaks coming from the membrane rather than the joint seal

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

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

FAQs: Roe End

Is hospital work, at somewhere like Luton and Dunstable Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Roe End off your patch?

No. Places such as Roe End are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What guarantee do you give on joint sealing?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
