Expansion joint sealing in Marsh Green

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Reopen bays and walkways only after the stated cure time
  • Keep scrapers and ploughs from dragging across joint sealant
  • Record the sealant used and the date in the O&M file
  • Clear dirt from joint lines during routine cleaning

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.

How we handle expansion joint sealing in Marsh Green

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. If you’re dealing with sealant peeling off one face of the joint and water dripping through deck or ramp joints, we can help, whatever the surface. Searching for sealant specialists in Marsh Green? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places such as Marsh Green, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Where floor joints take the most wear near Marsh Green

The sea is no more than about 1 mile from Marsh Green. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Marsh Green sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

Hospitals like Whitecroft Hospital (5 miles north-east of Marsh Green) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Marsh Green is about 6 miles south-west of Newport, in the Isle of Wight. Commercial clients in Marsh Green can call on us for movement joints, as part of our coverage of the Isle of Wight. 125 places across the Isle of Wight fall within our area, Marsh Green among them.

Close to Marsh Green, our area also takes in Chilton Green (1 mile north-west), Hulverstone (2 miles north-west), Brookgreen (2 miles west), Brook (2 miles north-west) and Dunsbury (3 miles north-west).

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Proprietary pre-formed expansion joint systems
  • Concrete or masonry repairs along the arrises
  • A joint that has to be widened or re-detailed before it can work

If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

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

How the job changes by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally 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. Jobs in and around smaller places like Marsh Green are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Your questions answered

Is a smaller place like Marsh Green outside your area?

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

Our building in Marsh Green is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How long does movement joint sealing take?

The metres of joint, the access and the amount of removal decide it. Typically it 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.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do you guarantee expansion joint work?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

Do you need expansion joint sealing in Marsh Green?

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Site and facilities staff are often the first to spot these:

  • Sealant pulling off the joint face
  • Movement joints with split or torn sealant
  • Water getting into the wall through a failed joint
  • Spalled or broken joint edges in floors and decks

In a school such as Brighstone Church of England Aided Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
