Questions we are asked in Broad Street

Is Broad Street off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Our building in Broad Street is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

What will the job cost?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email the details over with a description of the work.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do the joint edges need to be sound before sealing?

Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first.

Do you reseal car park expansion joints?

Yes, we do. These joints take wheels, salt and water, so product choice matters, and we will tell you if any edges need repairing first.

Expansion joint sealing in Broad Street, done properly

A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on podiums and floor movement joints, precast concrete panel joints and car park decks and ramps, and the usual reasons a site gets in touch are expansion joints filled with dirt and stones and layers of sealant in a movement joint. A specialist sealant contractor works differently from a general builder: on jobs in Broad Street, preparation and product choice get the time they need.

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

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Expansion joint sealing in Broad Street: the local picture

Broad Street lies within about 3 miles of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Rainfall across the South East, Broad Street included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

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

Broad Street is about 5 miles north-east of Hastings, in East Sussex. Anywhere in TN36, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Broad Street is one of 308 places we cover in East Sussex for movement joints. Our Brighton page has more on work in that area.

Aftercare for building managers

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Report split or peeling joint sealant early
  • Inspect movement joints alongside other routine building checks
  • Note which joints were done, when, and with what
  • Reopen bays and walkways only after the stated cure time

Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. For buildings around smaller places like Broad Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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

How the job changes by surface

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Car park decks and ramps

Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • The product specified
  • How much there is to seal
  • Joint width, depth and condition
  • Site requirements such as inductions and permits

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Your programme or deadline
  • Whether the building will be occupied during the work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Signs you need expansion joint sealing in Broad Street

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

These are often picked up first by site or facilities staff:

  • Torn sealant in brick or block movement joints
  • Spalled or broken joint edges in floors and decks
  • Expansion joints filled with dirt and stones
  • Damp inside where a wall movement joint has failed

For an estate such as Conquest Hospital, which lies south-west of Broad Street, the joints in ramps, decks and long building elevations all need attention over time.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • Their plan for phasing and protecting the area
  • Their approach to joint depth and backing

How to choose a sealant contractor

On site: what to expect

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 Broad Street are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  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. 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.

Getting the site ready

  • Make sure the joints can be reached
  • Confirm the product named in the specification
  • Let us know about inductions and permits

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.
