Expansion joint sealing in Stratfield Saye

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors on sites in Stratfield Saye. If you’re dealing with rain penetration at brick or block movement joints and arrises breaking up along floor joints, we can help, whatever the surface. Whoever orders the work in Stratfield Saye, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Jobs around smaller places like Stratfield Saye are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Things that typically lead to an enquiry:

  • Brittle, chalky sealant on external joints
  • Torn sealant in brick or block movement joints
  • Arrises breaking up along floor joints
  • Rain penetration at brick or block movement joints

Parks like Campbell Court Office Park, 2.1 miles south-west of Stratfield Saye, combine paved areas, car parks and building elevations, each with joints that move.

Questions to ask before you appoint anyone

Common questions from Stratfield Saye clients

Will you take on work at estates like Campbell Court Office Park, close to Stratfield Saye?

Yes. We cover Stratfield Saye and the area around it, including industrial estates, business parks and retail parks such as Campbell Court Office Park. Photos and a short description are enough for a first look.

Must our site in Stratfield Saye stop work while the joints are done?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Will you just go over the old sealant?

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

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Floors, slabs and movement joints in Stratfield Saye

Less than 3 miles from Stratfield Saye there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier 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.

Phasing is what makes joint work possible on busy sites such as Riseley Business Park (2.6 miles east of Stratfield Saye): one bay, aisle or car park row at a time.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Stratfield Saye, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. 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.

What the job involves on each surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Put movement joints on the planned maintenance inspection round
  • Treat a small split as a warning, not a cosmetic issue
  • Check joints after long freezing spells
  • Note which joints were done, when, and with what

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we’ll tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.

Why deal with it now?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex. We cut out the old seal and prepare the faces every time. Halls, stores and units around places like Stratfield Saye may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
