Common questions from Brookstreet clients

Is Brookstreet too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is hospital work, at somewhere like Braintree Community 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.

What do you charge?

We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.

Can you work on car park ramps and decks?

Yes. Let us know the opening hours and which levels or bays have to stay available.

Are expansion joints and movement joints the same thing?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you guarantee expansion joint work?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

Expansion joint sealing for commercial buildings in Brookstreet

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. If you are dealing with arrises breaking up along floor joints and brittle, chalky sealant on external joints, we can help. Most enquiries from Brookstreet 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.

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

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Expansion joint sealing in Brookstreet: the local picture

Brookstreet lies roughly 33 miles out from central London. The roads out of London are lined with trade parks and distribution sheds. Rainfall across the South East, Brookstreet included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

Schools such as The Flitch Green Academy have movement joints in their walls and floors that are easy to overlook. Another example is Hoblongs Industrial Estate, 1.3 miles west of Brookstreet, where floors and yards would be done in stages around the occupiers.

Brookstreet is about 7 miles west of Braintree, in Essex. Across the CM6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 644 places in Essex, from busy centres to rural villages. Our London page has more on work in that area, about 33 miles away.

Anyone looking for expansion joint sealing in CM6 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We also cover Little Dunmow (1 mile east), Felsted (1 mile east), North End (1 mile south), Causeway End (2 miles south-east) and Watch House Green (2 miles east). A short drive away, we cover Chelmsford (9 miles south), Braintree (7 miles east), Harlow (14 miles south-west), Maldon (15 miles south-east), Witham (11 miles south-east) and Saffron Walden (13 miles north-west).

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints or a site visit fills the gaps.

Podium joints

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

Looking after the joints

A few simple habits keep the new joints working:

  • Keep traffic off new joints until the cure time is up
  • Keep product details with the building records for the next reseal
  • Keep scrapers and ploughs from dragging across joint sealant
  • Include every elevation and deck joint in periodic inspections

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth and we’ll tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites around Brookstreet. Several sites can go on one quote, which keeps the paperwork simple.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Around Brookstreet, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • Coloured sealants to suit the setting, where available
  • Public liability insurance in place
  • Products installed to the manufacturer’s instructions
  • Old sealant cut out, never sealed over

See our cost guide and our accreditations.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Brookstreet, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. Old sealant and debris are cut out of every joint.
  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.

Preparing the site

  • Move anything stored against the joints
  • Tell staff and tenants when we will be in
  • Have the specification and drawings to hand

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What we are called out for in Brookstreet

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it.

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

  • Movement joints with split or torn sealant
  • Spalled or broken joint edges in floors and decks
  • Hardened, cracked sealant on exposed facades
  • Car park joints leaking onto vehicles below

Hospitals like Braintree Community Hospital, 5.8 miles to the east of Brookstreet, have multi-storey or surface car parks whose joints carry vehicles round the clock.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
