Questions about Andover

Can you work on a hospital site such as Andover Hospital (Grounds)?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do we have to stop operations in Andover while the joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Can you fill joints where the arrises have spalled?

Edge condition is recorded when we look at the floor. Damaged edges are flagged up front so the filling isn’t wasted.

Can the warehouse stay open while you work?

Normally only the zone we are working in has to close. Each zone reopens when the product can take traffic and the next zone follows.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What information helps you price floor joint sealing?

Use our quote form, or email photographs and a plan, with the traffic on each area. We then send a fixed quote with the product and phasing set out.

How we handle floor joint sealing in Andover

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Pricing depends on the length of joint, how worn the edges are and when we can get in, and the quote is fixed before we mobilise. The enquiries we see most involve grimy joint lines spoiling a showroom floor and cracked and crumbling joint fill, on forklift and pallet-truck routes, loading bays and retail and showroom floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Andover is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In Andover, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a town like Andover, we try to group jobs for the same client into one visit. Tell us when the building is open and we will plan to suit.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. We tell you when each zone can carry trucks again and move on to the next.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Make sure the joints can be reached

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Looking after the joints

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

  • Tell us about strong cleaning chemicals before we quote
  • Keep trucks off new joints until we say they’re ready
  • Expect fillers on young slabs to need a top-up
  • Sweep debris out of open joints until they can be filled

Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.

Every vehicle on a busy aisle hits a damaged joint. Sorting it early looks after your equipment as well as the slab.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Location, for remote and island sites

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Any specification or named product
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • Where the site is, with the postcode

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, phone 01277 525 020 or email drawings and photos.

Commercial clients in Andover

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Andover can sit alongside others in a wider programme.

What the job involves on each surface

Saw-cut induced joints

Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They start narrow and widen as the concrete dries so trafficked runs need a filler that holds the arrises.

Retail and showroom floors

Retail joints see trolleys, footfall and scrubber-driers. The product is chosen for that traffic and the appearance is part of the brief.

Floor joint sealing in Andover: the local picture

Andover sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. At about 63 miles from central London, Andover is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

In a school such as St John the Baptist Catholic Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. A healthcare site such as Andover Hospital (Grounds) (to the north-west of Andover) depends on car parks, ramps and service yards whose joints take traffic all day. At a retail site such as Northern Avenue Retail Park, less than half a mile north-east of Andover, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.

Andover is about 17 miles west of Basingstoke, in Hampshire. Across the SP10 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Our Southampton page has more on work in that area, about 21 miles away.

We take on floor joints across the SP10 and SP11 postcode area, for business premises of every kind. We cover commercial and managed buildings on High Street, Goddard Square and London Road.

Andover ranks among the main centres of Hampshire, with offices, shops, schools and other public and commercial buildings, and we cover them all.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Level or flatness problems across the floor
  • A floor that rocks at the joints, which needs a structural fix
  • Wide or random cracking that suggests a structural issue

If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.
