Expansion joint sealing around Ashlett: what changes locally

Ashlett is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. The 3 miles around Ashlett take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Sites like Coldeast, 4 miles to the north-east of Ashlett, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Schools such as Fawley Infant School have movement joints in their walls and floors that are easy to overlook.

Ashlett is about 4 miles south-east of Hythe, in Hampshire. We send applicators to Ashlett for movement joints. Our Hampshire coverage takes in 723 places. We also cover Southampton, around 7 miles from Ashlett.

If you need expansion joint sealing in SO45, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Just outside Ashlett, we also work in Stonehills (1 mile south-west), Fawley (1 mile west), Sprat's Down (1 mile south), Calshot (1 mile south-east) and Blackfield (1 mile south-west).

Expansion joint sealing for commercial buildings in Ashlett

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Ashlett. Most enquiries involve new sealant over old, now failing and debris jammed in movement joints, on precast concrete panel joints, podiums and floor movement joints and brickwork movement joints. Looking for mastic applicators who cover Ashlett? We have been sealing commercial buildings since 2005.

In and around smaller places like Ashlett, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers
  • How accessible the joints are
  • Which sealant the job calls for

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • Where the site is, with the postcode
  • Clear photographs of the problem areas
  • Your programme or deadline
  • The type of building and who uses it

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Cracking or settlement that calls for an engineer’s assessment
  • Changing the joint layout or spacing of a structure
  • Proprietary pre-formed expansion joint systems

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.

Surfaces we seal

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

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Ashlett, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

Your questions answered

Do you take on work at healthcare sites like Coldeast?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Ensign Way Business Park, by Ashlett?

Yes. Our area takes in Ashlett and its surroundings, with estates and business parks such as Ensign Way Business Park included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

What causes movement joint sealant to fail?

The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

What’s the difference between an expansion joint and a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably, and the sealing method is much the same.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Common problems we fix in Ashlett

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Clients typically get in touch after noticing something like this:

  • Car park joints leaking onto vehicles below
  • Sealant pulling off the joint face
  • Water getting into the wall through a failed joint
  • Expansion joints filled with dirt and stones

For buildings at a park such as Ensign Way Business Park, 2.2 miles north of Ashlett, brick and panel movement joints are easy to forget until one leaks.

What your quote should include

  • Can the work be phased to keep areas open?
  • How joint depth will be controlled
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

After the work

To get the most from the new sealant:

  • Avoid parking heavy plant or pallets on joint lines
  • Include every elevation and deck joint in periodic inspections
  • Leave barriers in place until fresh joint sealant has cured
  • Treat a small split as a warning, not a cosmetic issue

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file so future maintenance isn’t guesswork.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We will tell you which movement joints need doing now and which can wait.
