Expansion joint sealing in Hill Brow

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

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 we visit if they don’t show enough.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

Expansion joint sealing for commercial buildings in Hill Brow

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on blockwork control joints, precast concrete panel joints and car park decks and ramps, and the usual reasons a site gets in touch are new sealant over old, now failing and expansion joints filled with dirt and stones. A specialist sealant contractor works differently from a general builder: on jobs in Hill Brow, preparation and product choice get the time they need.

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

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

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • A joint that has to be widened or re-detailed before it can work
  • Crumbling edges that would give a new bead nothing sound to grip
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

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

Where floor joints take the most wear near Hill Brow

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. Hill Brow is about 47 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Another example is Ham Barn Business Park, which lies north-west of Hill Brow, where floors and yards would be done in stages around the occupiers. Schools like Liss Junior School often have long brick elevations with movement joints that age quietly.

Hill Brow is about 3 miles north-east of Petersfield, in Hampshire. Commercial clients in Hill Brow use us for work on movement joints. Across Hampshire, 723 places are covered, including Hill Brow. We also cover Portsmouth, some 18 miles away.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically 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 we clear our waste as we work. For a building around Hill Brow, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • For older buildings, check the asbestos register before work

Advice

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • Joint width, depth and condition
  • How much existing material needs removing
  • The product specified
  • The site’s rules and procedures

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • When you need the work done
  • The site address and postcode
  • Anything awkward about access or site hours

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or email us.

What we’re called out for in Hill Brow

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.

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

  • Brittle, chalky sealant on external joints
  • Torn sealant in brick or block movement joints
  • Rain penetration at brick or block movement joints
  • Previous reseals laid over old sealant

For an estate such as Petersfield Community Hospital, 3.5 miles to the south-west of Hill Brow, the joints in ramps, decks and long building elevations all need attention over time.

What to look for in a quote

  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Common questions from Hill Brow clients

Is Hill Brow too small for you to travel to?

Not at all. Hill Brow is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is Upper Adhurst Industrial Park, near Hill Brow, within your area?

Yes. Estates, retail parks and business parks around Hill Brow, Upper Adhurst Industrial Park among them, are all within reach. A few photos and the unit address let us price the work.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Is movement joint sealing guaranteed?

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

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
