Expansion joint sealing across Petersfield

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

How we handle expansion joint sealing in Petersfield

Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. We work on cladding panel joints, brickwork movement joints and precast concrete panel joints, and the failures we’re asked to look at most are brittle, chalky sealant on external joints and arrises breaking up along floor joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Petersfield it comes down to the same thing: the right product in a properly prepared joint.

Car parks and yards in towns like Petersfield take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.

Our 12-month guarantee is about workmanship, not 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.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Questions about Petersfield

Is hospital work, at somewhere like Petersfield Hospital, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will our site in Petersfield have to close for joint sealing?

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can you seal joints in cold or wet weather?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.

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

They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading.

Do you reseal car park expansion joints?

Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.

What do you charge?

We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.

What happens if it’s left?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. We agree phasing with you before work starts. For businesses and landlords in Petersfield, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Commercial clients in Petersfield

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

General trades versus a specialist

Some joints are best left to specialists: for example 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.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Where floor joints take the most wear near Petersfield

At about 50 miles from central London, Petersfield is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Rainfall across the South East, Petersfield 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.

Schools like Petersfield Infant School often have long brick elevations with movement joints that age quietly. Estates like Upper Adhurst Industrial Park (1.9 miles north-east of Petersfield) combine warehouse slabs, yards and loading bays, all with joints under wheels. Hospitals like Petersfield Hospital (to the west of Petersfield) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If you have more than one building in Petersfield, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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.

Before we start on site

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

Quotes

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Advice

Quoting for work in Petersfield

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • Any access equipment needed
  • Whether the work must be split into stages

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • The postcode of the building
  • What the building is and how it’s used
  • Clear photos of the problem areas

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.
