Need expansion joint sealing in Lower Basildon?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Do you need expansion joint sealing in Lower Basildon?

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again unless width and product are reviewed.

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

  • Water getting into the wall through a failed joint
  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face
  • Torn sealant in brick or block movement joints

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

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Will RAMS and insurance details be available?
  • What level of public liability insurance do they hold?
  • How the existing material will be dealt with

Questions we’re asked in Lower Basildon

Will our site in Lower Basildon have to close for joint sealing?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Is Lower Basildon too small for you to travel to?

Not at all. Lower Basildon is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you just go over the old sealant?

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

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How soon can the area be used again?

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

What causes movement joint sealant to fail?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing, because the fix differs.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. Smaller jobs around Lower Basildon can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Agree which areas must stay open
  • Flag any permit to work we will need
  • Arrange parking or a loading space

Quotes

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.

What affects the price in Lower Basildon

Before we quote, we look at:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

However big the job, these details speed things up:

  • When you need the work done
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email us.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
