About our expansion joint sealing in Fox

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. The enquiries we see most involve weathered movement joint sealant that no longer flexes and water dripping through deck or ramp joints, on blockwork control joints, podiums and floor movement joints and car park decks and ramps. One point of contact handles commercial sealant work in Fox from the first photos to the final walk-round, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Fox have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why deal with it now?

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 and we’ll tell you honestly. Around Fox, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Why us?

  • Matching to RAL references, product permitting
  • A fixed quote before work starts
  • Workmanship guaranteed for 12 months
  • Fully insured

Different surfaces, different methods

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.

Diagnose, treat, sign off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Fox are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  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. 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.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

Your questions answered

Is Fox off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Andover War Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Which product is best for expansion joints?

The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane, and the specification has the final say.

How long does movement joint sealing take?

It usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote, including any phasing.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you need expansion joint sealing in Fox?

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.

Look out for the following:

  • Expansion joints filled with dirt and stones
  • Brittle, chalky sealant on external joints
  • Sealant pulling off the joint face
  • Spalled or broken joint edges in floors and decks

Office parks like Weyhill Business Park, 2.1 miles north-east of Fox, have decks, ramps and clad elevations whose joints take movement every day.

Expansion joint sealing around Fox: points for this area

Fox sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. At about 68 miles from central London, Fox is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Large sites such as Andover War Memorial Hospital, 4.2 miles north-east of Fox, have car parks, service roads and long elevations with movement joints in brick and panels. For a school such as Amport Church of England Primary School, playground and building joints can be done in the holidays.

Fox is about 5 miles west of Andover, in Hampshire. We cover Fox, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, large and small. Southampton is covered too, some 21 miles away.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Concrete or masonry repairs along the arrises
  • Proprietary pre-formed expansion joint systems
  • Movement on a scale no sealant is meant to absorb

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
