Expansion joint sealing in Combe

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Movement on a scale no sealant is meant to absorb
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.

Surfaces we seal

  • Brickwork movement joints
  • Precast concrete panel joints
  • Car park decks and ramps
  • Podiums and floor movement joints
  • Cladding panel joints
  • Blockwork control joints

Expansion joint sealing for commercial buildings in Combe

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. If you’re dealing with car park joints leaking onto vehicles below and weathered movement joint sealant that no longer flexes, we can put it right, on car park decks and ramps, blockwork control joints and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Combe, preparation and product choice get the time they need.

Halls, schools and small commercial buildings near places like Combe have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check joints after long freezing spells
  • Keep stones and debris out of open joint lines
  • Keep racking legs and heavy point loads off floor joints
  • Reopen bays and walkways only after the stated cure time

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Warehouse floors and decks around Combe

Rainfall across the South East, Combe included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At about 61 miles from central London, Combe is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

Another example is Hanborough Business Park (1.9 miles south-east of Combe), where floors and yards would be done in stages around the occupiers. In a school such as Combe CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Combe is about 5 miles north-east of Witney, in Oxfordshire. Businesses, contractors and managing agents in Combe use us for work on movement joints. Combe is one of 423 places in Oxfordshire on our list for movement joints. We also cover Oxford, some 10 miles away.

Questions we are asked in Combe

Is Wroslyn Road Industrial Estate, near Combe, within your area?

Yes. We cover Combe and the area around it, including industrial estates, business parks and retail parks such as Wroslyn Road Industrial Estate. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is Combe too small for you to travel to?

No. Places such as Combe are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What timescale should we allow for resealing expansion joints?

Expect anything from part of a day to a couple of weeks, depending on joint lengths, widths and access and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. If others near Combe need work, visits can be combined. A fixed quote is given before anything starts.

  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Point out any areas we must not close
  • Warn occupants and staff about the work

What affects the price in Combe

We price every job individually. The main factors are:

  • Location, for remote and island sites
  • Access and working height
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Whether an asbestos survey exists
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

For a fixed quote, call 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.

Signs you need expansion joint sealing in Combe

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again.

Any of the following is a good reason to get the joints checked over:

  • Joints where the bead has lost adhesion
  • Chipped joint edges on forklift routes
  • Damp inside where a wall movement joint has failed
  • Hardened, cracked sealant on exposed facades

Estates like Wroslyn Road Industrial Estate, 1.5 miles to the south of Combe, combine warehouse slabs, yards and loading bays, all with joints under wheels.
