Expansion joint sealing near Romsey

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 Romsey?

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.

Typical triggers for a call:

  • Hardened, cracked sealant on exposed facades
  • Debris jammed in movement joints
  • Damp inside where a wall movement joint has failed
  • Spalled or broken joint edges in floors and decks

Schools such as Romsey Primary School have movement joints in their walls and floors that are easy to overlook.

What to look for in a quote

  • What site paperwork they can supply
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?

Our contractor checklist

Expansion joint sealing in Romsey

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. The enquiries we see most involve joints where the bead has lost adhesion and torn sealant in brick or block movement joints, across cladding panel joints, car park decks and ramps and precast concrete panel joints. For commercial sealant work in Romsey, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Towns such as Romsey normally have an industrial estate or a few business units, with warehouse floors and loading areas. Small units are often busy, so joints are done at times that suit the occupier.

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

Joints that move: notes for Romsey

Rainfall across the South East, Romsey 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, while winter salting gets into any joint left open. Less than 3 miles from Romsey there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

Another example is Romsey Industrial Estate, which lies west of Romsey, where floors and yards would be done in stages around the occupiers. Large sites such as Romsey Hospital, under half a mile to the south of Romsey, have car parks, service roads and long elevations with movement joints in brick and panels.

Romsey is about 6 miles west of Eastleigh, in Hampshire. Anywhere in SO51, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, including Romsey. Southampton is covered too, some 6 miles away.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most work in Romsey is one building at a time: a school, a unit, an office or a block. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Your questions answered

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

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Can you take on a job at a hospital such as Romsey Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

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.

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

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

What if the joint edges are damaged?

The edges have to be sound. If they’re damaged, we’ll say so before any sealing so you are not paying for a bead that won’t hold.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Quoting for work in Romsey

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas
  • Any dates the work must fit around
  • What the building is and how it’s used

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email us.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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

Different surfaces, different methods

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.

Why act early in Romsey

Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. In a town such as Romsey, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Renewing them before water gets in protects the fabric.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
