Expansion joint sealing in Clanville

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

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Proprietary pre-formed expansion joint systems
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Surfaces we seal

  • Precast concrete panel joints
  • Brickwork movement joints
  • Podiums and floor movement joints
  • Blockwork control joints
  • Cladding panel joints
  • Car park decks and ramps

Expansion joint sealing in Clanville, done properly

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. If you have torn sealant in brick or block movement joints and chipped joint edges on forklift routes, we can help, whatever the surface. Looking for mastic applicators who cover Clanville? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

In and around smaller places like Clanville, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Expansion joint sealing around Clanville: points for this area

Clanville is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Clanville is about 65 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Another example is Portway Industrial Estate (2.4 miles south-east of Clanville), where floors and yards would be done in stages around the occupiers. For a school such as Appleshaw St Peter's CofE Primary School, playground and building joints can be done in the holidays.

Clanville is about 4 miles north-west of Andover, in Hampshire. We cover Clanville, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. There’s a separate page for Southampton, roughly 23 miles from Clanville.

Work on movement joints is covered throughout SP11, for business premises of every kind. Close to Clanville, our area also takes in Appleshaw (1 mile south-west), Redenham (1 mile west), Penton Mewsey (1 mile south-east), Chute Forest (1 mile north-west) and Penton Grafton (1 mile south). A short drive away, we cover Andover (4 miles south-east), Tidworth (5 miles west), Weeke (15 miles south-east), Ludgershall (4 miles west), Whitchurch (9 miles east) and East Anton (4 miles east).

Local landmarks in Clanville

Your questions answered

Is Clanville too far out for you?

Not at all. Clanville is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on work at healthcare sites like Andover War Memorial Hospital?

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.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Are your applicators CSCS-carded?

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

How long will the joint resealing take?

It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote.

How the job changes by surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves.

Signs you need expansion joint sealing in Clanville

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.

Site and facilities staff are often the first to spot these:

  • Sealant pulling off the joint face
  • Layers of sealant in a movement joint
  • Torn sealant in brick or block movement joints
  • Joints packed with grit and debris

Hospital campuses such as Andover War Memorial Hospital (to the south-east of Clanville) grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Proof of insurance
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long

How to choose a sealant contractor

How the quote is worked out

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • How accessible the joints are
  • Quantities, in metres or numbers
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • When you need the work done
  • The postcode of the building
  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Clanville may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Move anything stored against the joints
  • Arrange parking or a loading space

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

Advice

Why it’s worth doing now in Clanville

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. One visit to deal with every failing joint makes more sense than several trips to a place like Clanville. Send photographs of each area and we will quote for the lot.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
