Expansion joint sealing for businesses in Queenborough

Your questions answered

Does the sea air around Queenborough change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you take on work at healthcare sites like Sheppey Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you fit around our working hours?

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

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Why has the sealant in our expansion joints split?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Expansion joint sealing for commercial buildings in Queenborough

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you’re dealing with arrises breaking up along floor joints and car park joints leaking onto vehicles below, we can put it right, on blockwork control joints, podiums and floor movement joints and brickwork movement joints alike. One point of contact handles commercial sealant work in Queenborough from the first photos to the final walk-round, whether it’s one building or several.

Small units near places like Queenborough are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

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

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Work in places the size of Queenborough is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We assess the joints on site or from photos, 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. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Agree which areas must stay open
  • Tell staff and tenants when we will be in
  • Have the specification and drawings to hand

Quotes

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Damaged metal nosings or cover plates over a joint
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

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

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Avoid parking heavy plant or pallets on joint lines
  • Include every elevation and deck joint in periodic inspections
  • Inspect exposed joints once the cold weather has passed
  • Clear dirt from joint lines during routine cleaning

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 confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

Surface by surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

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.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Joints that move: notes for Queenborough

Queenborough lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Rainfall across the South East, Queenborough included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Sites like Sheppey Community Hospital (1.9 miles east of Queenborough) carry ambulances, deliveries and visitors’ cars over their road and deck joints. At a retail site such as Neats Court Retail Park (0.5 miles south-east of Queenborough), joints in car parks, service yards and sales floors carry cars, cages and trolleys every day. Schools such as Queenborough School and Nursery have movement joints in their walls and floors that are easy to overlook.

Queenborough is about 2 miles west of Minster, in Kent. We send applicators to Queenborough for movement joints, handled exactly as we handle every other area. Queenborough is one of 931 places in Kent on our list. There’s a separate page for London, about 37 miles away.
