Expansion joint sealing for Loxwood sites

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

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Phasing around occupants
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • Clear photos of the problem areas
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email us.

Expansion joint sealing in Loxwood, done properly

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on blockwork control joints, brickwork movement joints and car park decks and ramps, and what we are called in for most is sealant pulling off the joint face and movement joints with split or torn sealant. One point of contact handles commercial sealant work in Loxwood from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For a site near Loxwood, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Joints that move: notes for Loxwood

At about 34 miles from central London, Loxwood is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. Loxwood is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Schools such as Loxwood Primary School have movement joints in their walls and floors that are easy to overlook.

Loxwood is about 9 miles west of Horsham, in West Sussex. Any commercial site in Loxwood is covered, whether it’s a single job or part of a planned programme. Our West Sussex coverage takes in 373 places, large and small. Sites around Brighton have their own page, roughly 24 miles from Loxwood.

Work on movement joints is covered throughout RH14, whatever the building. Among the streets we cover are High Street, Pond Close and Oak Grove, and sites on any of them can send details for a fixed quote. Sites close to Loxwood are covered too, including Ifold (1 mile south-west), Alfold Bars (1 mile north), Alfold (1 mile north), Plaistow (2 miles west) and Durfold Wood (3 miles west). Bigger towns within reach include Crawley (14 miles east), Horsham (9 miles east), Broadfield (14 miles east), Storrington (11 miles south), Billingshurst (5 miles south-east) and Bewbush (13 miles east).

Maintenance after handover

A few simple habits keep the new joints working:

  • Record the sealant used and the date in the O&M file
  • Keep traffic off new joints until the cure time is up
  • Report split or peeling joint sealant early
  • Clear dirt from joint lines during routine cleaning

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can ring 01277 525 020 or email the details over and send a picture.

When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Loxwood can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  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. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  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

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

What the job involves on each surface

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.

Car park decks and ramps

Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint
  • Changing the joint layout or spacing of a structure

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

Signs you need expansion joint sealing in Loxwood

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch.

Typical triggers for a call:

  • Rain penetration at brick or block movement joints
  • Expansion joints filled with dirt and stones
  • Sealant peeling off one face of the joint
  • Water dripping through deck or ramp joints

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

Before you book anyone

  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?

Your questions answered

Is Loxwood too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Will our site in Loxwood have to close for joint sealing?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

How long does movement joint sealing take?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Are expansion joints and movement joints the same thing?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
