Expansion joint sealing near Shiplake

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing for commercial buildings in Shiplake

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you’re dealing with movement joints with split or torn sealant and spalled or broken joint edges in floors and decks, we can put it right, on blockwork control joints, brickwork movement joints and precast concrete panel joints alike. A specialist sealant contractor works differently from a general builder: in Shiplake, that means joint design, primers and backing rod as standard.

In and around smaller places like Shiplake, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

FAQs: Shiplake

Does your area include sites such as Castle End Business Park, near Shiplake?

Yes, sites like Castle End Business Park are within our area, along with the rest of Shiplake. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is Shiplake off your patch?

Not at all. Shiplake is within our area. 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.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Where floor joints take the most wear near Shiplake

Rainfall across the South East, Shiplake 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 gritting in cold spells finds its way into open joints. Central London is about 35 miles from Shiplake. The roads out of London are lined with trade parks and distribution sheds.

For estates staff at a university like University of Reading, 1.1 miles south-west of Shiplake, building and paving joints are part of the planned maintenance list. Schools such as Shiplake Church of England School have movement joints in their walls and floors that are easy to overlook.

Signs you need expansion joint sealing in Shiplake

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.

Site and facilities staff are often the first to spot these:

  • Water getting into the wall through a failed joint
  • Expansion joints split through the centre of the bead
  • Spalled or broken joint edges in floors and decks
  • Previous reseals laid over old sealant

Parks like Castle End Business Park (2.5 miles east of Shiplake) combine paved areas, car parks and building elevations, each with joints that move.

What your quote should include

  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?
  • How they handle RAMS and site documents

How to choose a sealant contractor

How the job changes by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Shiplake, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  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.

Related advice

Doing it in-house

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 easy to get wrong without experience.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What we can’t put right

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

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Cracking or settlement that calls for an engineer’s assessment
  • Proprietary pre-formed expansion joint systems

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