Expansion joint sealing for businesses in Poynings

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Do you need expansion joint sealing in Poynings?

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.

Look out for the following:

  • Brittle, chalky sealant on external joints
  • Chipped joint edges on forklift routes
  • Water dripping through deck or ramp joints
  • Damp inside where a wall movement joint has failed

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

What your quote should include

  • What the guarantee covers, and for how long
  • Is the sealant right for the movement and the substrate?
  • Will RAMS and insurance details be available?
  • How the existing material will be dealt with

Our contractor checklist

Expansion joint sealing in Poynings

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on car park decks and ramps, brickwork movement joints and cladding panel joints, and the failures we are asked to look at most are arrises breaking up along floor joints and expansion joints filled with dirt and stones. Looking for mastic applicators who cover Poynings? We’ve been sealing commercial buildings since 2005.

For a site near Poynings, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Where we work in Poynings

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Jobs in and around smaller places like Poynings are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Share your working hours and any access restrictions

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email drawings and photos.

Maintenance after handover

After handover, these steps help:

  • Inspect exposed joints once the cold weather has passed
  • Put movement joints on the planned maintenance inspection round
  • Keep scrapers and ploughs from dragging across joint sealant
  • Keep racking legs and heavy point loads off floor joints

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

How the quote is worked out

Before we quote, we look at:

  • Which sealant the job calls for
  • The total length or number of joints
  • Whether old sealant has to be cut out first
  • Any access equipment needed

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or email us.

What the job involves on each surface

Podium joints

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

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Questions about Poynings

Would you work within a site like Southlands Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Poynings outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Warehouse floors and decks around Poynings

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Poynings. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

For an occupier at a site such as Aviation Trading Estate, which lies north of Poynings, the joints at loading doors and dock levellers typically see the hardest wear. Another example is Henfield Business Park, 2.9 miles to the north-west of Poynings, where floors and yards would be done in stages around the occupiers.

Poynings is about 4 miles north of Brighton and Hove, in West Sussex. We cover commercial sites throughout Poynings, for single jobs and planned programmes alike. We work across 373 places in West Sussex.
