Expansion joint sealing across New Alresford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in New Alresford, done properly

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. Most enquiries involve rain penetration at brick or block movement joints and leaks through car park deck joints onto the level below, on cladding panel joints, car park decks and ramps and podiums and floor movement joints. A single leaking joint is often how a building in New Alresford first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural business units around smaller places such as New Alresford often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Joints that move: notes for New Alresford

The South East is one of the drier parts of the UK. 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. New Alresford is about 54 miles from central London. The roads out of London are lined with trade parks and distribution sheds.

Schools such as Sun Hill Junior School have movement joints in their walls and floors that are easy to overlook.

New Alresford is about 7 miles east of Winchester, in Hampshire. Across the SO24 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. New Alresford is one of 723 places in Hampshire on our list for movement joints. For work in that direction, see our Southampton page, about 15 miles away.

We take on movement joints across the SO24 postcode area, whatever the building. If your site is on Station Road, Elm Road and Bramble Hill or close by, we can quote for movement joints. Being close to the B3046 and B3047, New Alresford is easy to get to with materials and equipment. Close to New Alresford, our area also takes in Bishop's Sutton (2 miles east), Gundleton (2 miles east), Cheriton (2 miles south), Hinton Ampner (3 miles south) and Bramdean (3 miles south-east). Bigger towns within reach include Basingstoke (13 miles north), Winchester (7 miles west), Eastleigh (11 miles south-west), Horndean (14 miles south-east), Chandler's Ford (12 miles south-west) and Alton (9 miles north-east).

Your questions answered

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

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

What documents will you need to give us for a job in New Alresford?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Do you reseal car park expansion joints?

Yes. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. What matters most for a job in New Alresford is a clear list of what needs doing. A fixed quote follows.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  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. 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

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Warn occupants and staff about the work

Common problems we fix in New Alresford

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.

Clients usually get in touch after noticing something like this:

  • Weathered movement joint sealant that no longer flexes
  • Previous reseals laid over old sealant
  • Debris jammed in movement joints
  • Car park joints leaking onto vehicles below

In and around New Alresford, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

Quoting for work in New Alresford

We price every job individually. The main factors are:

  • Working within restricted access windows
  • Location, for remote and island sites
  • Which sealant the job calls for
  • Backing rod, priming and other preparation

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Clear photographs of the problem areas
  • Any dates the work must fit around
  • The product your specification calls for
  • What the building is and how it’s used

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or use the quote form.

What happens if it’s left?

Resealing is typically the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
