Common questions from Brook Street clients

Is hospital work, at somewhere like Hartswood Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Brook Street outside your area?

No. Places such as Brook Street are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you seal car park deck joints?

Yes. We use a sealant designed for wheel loads and the expected movement.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Will you come and look before quoting?

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

Are you fully insured?

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

Expansion joint sealing in Brook Street

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Site teams most often ask us about spalled or broken joint edges in floors and decks and joints packed with grit and debris, on precast concrete panel joints, brickwork movement joints and cladding panel joints. One point of contact handles commercial sealant work in Brook Street from the first photographs to the final walk-round, whether it’s one building or several.

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

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Expansion joint sealing around Brook Street: how the place shapes the job

Brook Street 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. The 3 miles around Brook Street take in two named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Parks like Warley Hill Business Park (to the south-east of Brook Street) combine paved areas, car parks and building elevations, each with joints that move. Hospital campuses such as Hartswood Hospital (to the south-east of Brook Street) grow in stages, leaving movement joints wherever new blocks meet old.

Brook Street is about 2 miles south-west of Brentwood, in Essex. Across the CM14 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Essex coverage takes in 644 places, large and small. For work in that direction, see our London page, about 18 miles away.

Business premises anywhere in CM14 and RM3 are within our area. We cover commercial and managed buildings on River Road, Brook Road and Spital Lane and the roads nearby. Sites close to Brook Street are covered too, including South Weald (1 mile north), Harold Park (1 mile south-west), Harold Hill (2 miles west), Noak Hill (2 miles west) and St Vincent's Hamlet (2 miles north-west). Bigger towns within reach include Chelmsford (13 miles north-east), Basildon (8 miles east), Harlow (13 miles north-west), Canvey Island (15 miles south-east), Billericay (7 miles east) and Rayleigh (14 miles east).

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The size and state of each joint
  • The total length or number of joints
  • Working within restricted access windows
  • Any access equipment needed

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

How the job changes by surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Common problems we fix in Brook Street

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

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

  • Hardened, cracked sealant on exposed facades
  • Leaks through car park deck joints onto the level below
  • Previous reseals laid over old sealant
  • Expansion joints filled with dirt and stones

Another example is Childerditch Industrial Park (2.9 miles south-east of Brook Street), where floors and yards would be done in stages around the occupiers.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Proprietary pre-formed expansion joint systems
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Where we work in Brook Street

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Brook Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. 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.

Getting the site ready

  • Warn occupants and staff about the work
  • Flag any permit to work we will need
  • Agree which areas must stay open
