Expansion joint sealing in Milton Street, done properly

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on cladding panel joints, blockwork control joints and precast concrete panel joints, and what we are called in for most is damp inside where a wall movement joint has failed and new sealant over old, now failing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Milton Street is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Different surfaces, different methods

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Damaged metal nosings or cover plates over a joint
  • Crumbling edges that would give a new bead nothing sound to grip
  • Waterproofing layers buried beneath the sealant

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

What we seal

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

When to call us in Milton Street

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.

It’s worth sending us details if you spot any of the following:

  • Car park joints leaking onto vehicles below
  • Arrises breaking up along floor joints
  • Torn sealant in brick or block movement joints
  • Joints packed with grit and debris

Sites like Eastbourne District General Hospital (4.4 miles south-east of Milton Street) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Before you book anyone

  • How they handle RAMS and site documents
  • Whether their applicators hold CSCS cards
  • Their pre-qualification and accreditations
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Milton Street: questions and answers

Is Milton Street off your patch?

No. Small places get the same service as large ones. 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.

Can you work at a site such as Berwick Court Farm Business Park, by Milton Street?

Yes. Our area takes in Milton Street and its surroundings, with estates and business parks such as Berwick Court Farm Business Park included. Send details of the unit and the work through our quote form for a quick quote.

How long will the joint resealing take?

It 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. We confirm the timescale with the quote, including any phasing.

Can staff carry on working while you are here?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

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. Internal work is rarely affected.

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 to see the site first?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around Milton Street, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Before we start on site

  • Move anything stored against the joints
  • Point out parking and an unloading spot
  • Send your site hours and access windows

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Advice

Slabs, ramps and loading bays in Milton Street

Central London is about 49 miles from Milton Street. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. Rainfall across the South East, Milton Street 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.

Parks like Berwick Court Farm Business Park (0.7 miles north-west of Milton Street) combine paved areas, car parks and building elevations, each with joints that move. For estates staff at a university like University of Brighton (4.9 miles west of Milton Street), building and paving joints are part of the planned maintenance list.

Milton Street is about 4 miles north-east of Seaford, in East Sussex. We cover commercial sites throughout Milton Street, whether it’s a single job or part of a planned programme. Our East Sussex coverage takes in 308 places. We also cover Brighton, some 13 miles away.

After the work

A few simple habits keep the new joints working:

  • Note which joints were done, when, and with what
  • Brief car park operatives to protect joint lines during winter clearance
  • Leave barriers in place until fresh joint sealant has cured
  • Plan racking layouts so feet don’t land on a joint

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.
