Expansion joint sealing for commercial buildings in Kintbury

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. If you have brittle, chalky sealant on external joints and water getting into the wall through a failed joint, we can put it right. For commercial sealant work in Kintbury, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller community and commercial buildings around Kintbury have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Kintbury may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. Where areas have to stay open, we agree a phased sequence before starting.
  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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

Advice

When to call us in Kintbury

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

What tends to prompt an enquiry:

  • Expansion joints split through the centre of the bead
  • Expansion joints filled with dirt and stones
  • Rain penetration at brick or block movement joints
  • Joints where the bead has lost adhesion

Parks like Station Yard Business Park, 2.9 miles to the west of Kintbury, combine paved areas, car parks and building elevations, each with joints that move.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • How the existing material will be dealt with
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Quoting for work in Kintbury

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • The size and state of each joint

A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Before you send an enquiry

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

  • Specification clauses that apply
  • When you need the work done
  • How the joints are reached, and at what height
  • Whether the building will be occupied during the work

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or send photos by email.

Questions we are asked in Kintbury

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

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Is Kintbury too small for you to travel to?

Not at all. Kintbury is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What happens if it rains on the day?

Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Indoor joints can normally carry on regardless.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Kintbury can form part of a wider programme.

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’ll confirm them with the quote.

What the job involves on each surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.

Where floor joints take the most wear near Kintbury

Kintbury lies roughly 59 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Kintbury included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

Schools such as Kintbury St Mary's C.E. Primary School have movement joints in their walls and floors that are easy to overlook.

When something else is needed

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

  • A joint that has to be widened or re-detailed before it can work
  • Movement on a scale no sealant is meant to absorb
  • Leaks coming from the membrane rather than the joint seal

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

Joints and surfaces we work on

  • Brickwork movement joints
