About our expansion joint sealing in Chadlington

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. The enquiries we see most involve expansion joints split through the centre of the bead and arrises breaking up along floor joints, across brickwork movement joints, podiums and floor movement joints and car park decks and ramps. One point of contact handles commercial sealant work in Chadlington from the first photographs to the final walk-round, whether it’s one building or several.

Halls, schools and small commercial buildings near places like Chadlington have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Chadlington are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand
  • Agree which areas must stay open

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Expansion joint sealing around Chadlington: points for this area

At about 67 miles from central London, Chadlington is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

In a school such as Chadlington Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. In and around Chadlington, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Chadlington is about 8 miles north of Witney, in Oxfordshire. Chadlington sits inside our coverage and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Chadlington is one of 423 places we cover in Oxfordshire for movement joints. There’s a separate page for Oxford, about 16 miles away.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Inspect movement joints alongside other routine building checks
  • Reopen bays and walkways only after the stated cure time
  • Keep racking legs and heavy point loads off floor joints
  • Treat a small split as a warning, not a cosmetic issue

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Cost factors for movement joints

To price the job, we consider:

  • Any access equipment needed
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites

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

What to include in your enquiry

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

  • Asbestos survey details if the building is older
  • Your programme or deadline
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available

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

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Chadlington: questions and answers

Is Chadlington off your patch?

No. Places such as Chadlington are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will our site in Chadlington have to close for joint sealing?

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

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you take on small jobs?

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

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.
