Expansion joint sealing in Emsworth

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing in Emsworth, done properly

Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. We work on podiums and floor movement joints, cladding panel joints and car park decks and ramps, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and torn sealant in brick or block movement joints. Most enquiries from Emsworth start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Work in a smaller place like Emsworth is typically one building at a time. That way the right materials come on the day and the job is done in one visit where possible.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Emsworth

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s normally not far behind, and a second visit means paying for access again. We can price a patch and a full reseal side by side. For buildings in places like Emsworth, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Your questions answered

Can being near the sea in Emsworth affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is a smaller place like Emsworth outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing and we will flag every length affected. Sealing over them leads to early failure.

When can you be on site?

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.

How long will the joint resealing take?

Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote, including any phasing.

Warehouse floors and decks around Emsworth

With the shore within about 1 mile, Emsworth counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. At about 58 miles from central London, Emsworth is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

Phasing is what makes joint work possible on busy sites such as Solent Retail Park (2.2 miles west of Emsworth): one bay, aisle or car park row at a time. At a retail site such as Central Retail Park, 2.1 miles west of Emsworth, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.

Emsworth is about 2 miles east of Havant, in Hampshire. Commercial clients in Emsworth can call on us for movement joints. Across Hampshire, 723 places are covered, including Emsworth. Our Portsmouth page has more on work in that area, about 7 miles away.

We take on movement joints across the PO10 postcode area, whatever the building. Buildings on High Street, Beacon Square and Seagull Lane are within our area for movement joints. Being close to the A27 and A259, Emsworth is easy to get to with materials and equipment. Close to Emsworth, our area also takes in Lumley (1 mile east), Westbourne (1 mile north-east), Denvilles (1 mile west), Southbourne (1 mile east) and Warblington (2 miles south-west). Nearby towns on our patch include Gosport (10 miles west), Fareham (11 miles west), Horndean (5 miles north-west), Waterlooville (5 miles north-west), Petersfield (11 miles north) and Purbrook (4 miles west).

What affects the price in Emsworth

What shapes the price:

  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Any access equipment needed
  • The product specified

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Before you send an enquiry

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

  • Asbestos survey details if the building is older
  • Your programme or deadline
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or send details through our quote form.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. If neighbouring businesses or buildings around Emsworth need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  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. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Point out any areas we must not close

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Leave barriers in place until fresh joint sealant has cured
  • Keep product details with the building records for the next reseal
  • Check joints after long freezing spells
  • Put movement joints on the planned maintenance inspection round

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Resealing early limits the damage.

Common problems we fix in Emsworth

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.

Common reasons buildings call us in:

  • Sealant pulling off the joint face
  • Leaks through car park deck joints onto the level below
  • Expansion joints filled with dirt and stones
  • Layers of sealant in a movement joint

Schools such as St James Church of England Controlled Primary School have movement joints in their walls and floors that are easy to overlook.

What your quote should include

  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • Who will actually carry out the work
  • Their plan for phasing and protecting the area

Our contractor checklist

Different surfaces, different methods

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
