Expansion joint sealing for businesses in Farnham Royal

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing for commercial buildings in Farnham Royal

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing. Most enquiries involve weathered movement joint sealant that no longer flexes and water dripping through deck or ramp joints, on podiums and floor movement joints, brickwork movement joints and car park decks and ramps. A specialist sealant contractor works differently from a general builder: on jobs in Farnham Royal, preparation and product choice get the time they need.

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

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Questions about Farnham Royal

Is hospital work, at somewhere like Spire Thames Valley Hospital, something you do?

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.

Does your area include sites such as Slough Trading Estate, near Farnham Royal?

Yes, sites like Slough Trading Estate are within our area, along with the rest of Farnham Royal. Send details of the unit and the work through our quote form for a quick quote.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use.

What’s the difference between an expansion joint and a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint, and either way it needs a sound seal.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Plan racking layouts so feet don’t land on a joint
  • Brief car park operatives to protect joint lines during winter clearance
  • Keep traffic off new joints until the cure time is up
  • Keep product details with the building records for the next reseal

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, speak to us on 01277 525 020 or email drawings and photos with photos.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually 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 our waste is bagged and taken away as we go. For a building around Farnham Royal, 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. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  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

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

Where floor joints take the most wear near Farnham Royal

Farnham Royal lies roughly 23 miles out from central London. The roads out of London are lined with trade parks and distribution sheds. Farnham Royal sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

Schools like St Mary's Farnham Royal CofE Primary School often have long brick elevations with movement joints that age quietly. Across sites such as Bath Road Shopping Park, which lies south-west of Farnham Royal, floor and movement joints can be sealed in phases so units keep working.

Farnham Royal is about 2 miles north of Slough, in Buckinghamshire. Farnham Royal sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. 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: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Common problems we fix in Farnham Royal

Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

Typical triggers for a call:

  • Hardened, cracked sealant on exposed facades
  • Joints where the bead has lost adhesion
  • Water dripping through deck or ramp joints
  • Chipped joint edges on forklift routes

Sites like Spire Thames Valley Hospital, 1.9 miles to the east of Farnham Royal, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
