Expansion joint sealing for Woodway sites

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

What happens if it’s left?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Halls, stores and units around places like Woodway may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

What you get with us

  • Joints cleaned back to sound surfaces
  • Fixed quotes based on photos, drawings or a visit
  • Standard and matched colours in many product ranges
  • One number for every site we cover

Expansion joint sealing in Woodway

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have water getting into the wall through a failed joint and brittle, chalky sealant on external joints, we can help, on cladding panel joints, car park decks and ramps and blockwork control joints alike. Whoever orders the work in Woodway, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Signs you need expansion joint sealing in Woodway

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Joints where the bead has lost adhesion
  • Rain penetration at brick or block movement joints
  • Brittle, chalky sealant on external joints
  • Car park joints leaking onto vehicles below

In a school such as Blewbury Endowed Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Woodway are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Before we start on site

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

Advice

Woodway: questions and answers

Do we have to stop operations in Woodway while the joints are sealed?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Is Woodway off your patch?

No. Places such as Woodway are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you seal on top of existing sealant?

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

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Warehouse floors and decks around Woodway

Central London is about 49 miles from Woodway. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Rainfall across the South East, Woodway included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

In and around Woodway, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What the job involves on each surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.

How the quote is worked out

These are the things that shape the price:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • The product your specification calls for
  • Whether an asbestos survey exists
  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or use the quote form.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Waterproofing layers buried beneath the sealant
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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