Expansion joint sealing in Whitley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Doing it in-house

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Expansion joint sealing in Whitley, done properly

We’ve been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. The enquiries we see most involve hardened, cracked sealant on exposed facades and layers of sealant in a movement joint, on brickwork movement joints, cladding panel joints and blockwork control joints. Whoever orders the work in Whitley, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Work in a smaller place like Whitley is normally one building at a time. Getting widths, depths and traffic details up front means one visit, not two.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Damaged metal nosings or cover plates over a joint
  • Crumbling edges that would give a new bead nothing sound to grip
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly.

What we seal

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

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Location, for remote and island sites
  • The size and state of each joint
  • Working within restricted access windows
  • The site’s rules and procedures

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Access details, including height
  • The site address and postcode
  • Asbestos survey details if the building is older

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or send details through our quote form.

What we are called out for in Whitley

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

Any of the following is a good reason to get the joints checked over:

  • Brittle, chalky sealant on external joints
  • Debris jammed in movement joints
  • Joints where the bead has lost adhesion
  • Layers of sealant in a movement joint

Hospital campuses such as Royal Berkshire Hospital, 1.5 miles north of Whitley, grow in stages, leaving movement joints wherever new blocks meet old.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Floors, slabs and movement joints in Whitley

Central London is about 38 miles from Whitley. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Whitley has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

For estates staff at a university like University of Reading - Whiteknights Campus, which lies north-east of Whitley, building and paving joints are part of the planned maintenance list. For a school such as John Madejski Academy, playground and building joints can be done in the holidays.

Why it’s worth doing now in Whitley

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we’ll plan around it. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What you get with us

  • Colour options checked against the specified product
  • One contact handling all your sites
  • Public liability insurance in place
  • Clear, fixed quotes

FAQs: Whitley

Is a smaller place like Whitley outside your area?

Not at all. Whitley is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Oldfield Retail Park, near Whitley?

Yes. We cover Whitley and the area around it, including industrial estates, business parks and retail parks such as Oldfield Retail Park. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so we’ll tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Work in places the size of Whitley is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
