Expansion joint sealing across Sandleheath

About our expansion joint sealing in Sandleheath

Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. We work on brickwork movement joints, precast concrete panel joints and car park decks and ramps, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and chipped joint edges on forklift routes. A specialist sealant contractor works differently from a general builder: in Sandleheath, that means joint design, primers and backing rod as standard.

For a site near Sandleheath, measurements and photos up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Sandleheath. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Leave it or put it right?

A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Around Sandleheath, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Sealing commercial buildings since 2005
  • Clear, fixed quotes
  • Colours confirmed for the specified product
  • One number for every site we cover

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Smaller jobs around Sandleheath can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Getting a fixed quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Where floor joints take the most wear near Sandleheath

Sandleheath 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, while winter salting gets into any joint left open. The 3 miles around Sandleheath take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Schools such as The Burgate School and Sixth Form have movement joints in their walls and floors that are easy to overlook. Warehouse floors on estates like Sandleheath Industrial Estate (less than half a mile north-east of Sandleheath) carry pallet trucks and forklifts over every saw-cut joint. At places like Fordingbridge Business Park, 0.7 miles south-east of Sandleheath, joints are sealed a section at a time so operations carry on.

Sandleheath is in Hampshire. Sandleheath sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 723 places across Hampshire fall within our area, Sandleheath among them. There’s a separate page for Southampton, roughly 19 miles from Sandleheath.

Commercial sites across SP6 are covered for movement joints. Among the streets we cover are Elms Close, Main Road and Old Brickyard Road. If your building is just outside Sandleheath, we cover Ashford (1 mile east), Alderholt (1 mile south), Damerham (1 mile north-west), Rockbourne (2 miles north) and Broxhill (2 miles south-west).

Surface by surface

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.

Questions we’re asked in Sandleheath

Can you work on a hospital site such as Fordingbridge Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Sandleheath outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Can the building stay open while you work?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Can you seal joints in cold or wet weather?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped and the way they’re sealed is similar.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement.

Can you quote from photos?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

Quoting for work in Sandleheath

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • Which sealant the job calls for
  • The site’s rules and procedures
  • Removal of failed or old sealant

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Concrete or masonry repairs along the arrises
  • A joint that has to be widened or re-detailed before it can work
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly.
