Expansion joint sealing in Riseden, done properly

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Riseden. We work on cladding panel joints, precast concrete panel joints and brickwork movement joints, and the failures we are asked to look at most are car park joints leaking onto vehicles below and rain penetration at brick or block movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Riseden, preparation and product choice get the time they need.

Smaller community and commercial buildings around Riseden have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Do you need expansion joint sealing in Riseden?

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way.

Look out for the following:

  • Movement joints with split or torn sealant
  • Layers of sealant in a movement joint
  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris

Hospital campuses such as Ticehurst House Hospital (to the south-west of Riseden) grow in stages, leaving movement joints wherever new blocks meet old.

How to choose a sealant contractor

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Riseden can be grouped with others nearby. A fixed quote is given before anything starts.

  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. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  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.

Before we start on site

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open

Getting a fixed quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Advice

Questions about Riseden

Is Riseden too small for you to travel to?

Not at all. Riseden is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Must our site in Riseden stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Can a joint be sealed if the edges are broken?

The edges have to be sound. If they’re damaged, we will say so before any sealing so you are not paying for a bead that won’t hold.

Do you guarantee expansion joint work?

The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Cost factors for movement joints

The price varies from site to site. It mainly depends on:

  • How much existing material needs removing
  • How much there is to seal
  • Working within restricted access windows
  • Travel to remote or island sites

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

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Different surfaces, different methods

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.

Warehouse floors and decks around Riseden

At about 36 miles from central London, Riseden is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

Around Riseden, each joint gets a filler or sealant matched to what crosses it and how much it moves.
