Expansion joint sealing for businesses in Lydd-on-Sea

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Lydd-on-Sea, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Move anything stored against the joints

Slabs, ramps and loading bays in Lydd-on-Sea

The sea is no more than about 1 mile from Lydd-on-Sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Rainfall across the South East, Lydd-on-Sea included, is lower than in many parts of the UK. 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.

On industrial estates such as Peak Industrial Park (2.2 miles west of Lydd-on-Sea), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Lydd-on-Sea is about 10 miles south-west of Hythe, in Kent. Lydd-on-Sea sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Kent coverage takes in 931 places, large and small. For work in that direction, see our Brighton page, about 48 miles away.

Postcode districts covered here: TN29 and TN28. Streets here include Taylor Road, Lade Fort Crescent and Williamson Road, and sites on any of them can send details for a fixed quote.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Around Lydd-on-Sea, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

After the work

Once the work is signed off, these steps help:

  • Record the sealant used and the date in the O&M file
  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Keep traffic off new joints until the cure time is up

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

Different surfaces, different methods

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

Lydd-on-Sea: questions and answers

Does a coastal location like Lydd-on-Sea affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do you cover business parks and estates near Lydd-on-Sea, such as Peak Industrial Park?

Yes, sites like Peak Industrial Park are within our area, along with the rest of Lydd-on-Sea. A few photographs and the unit address let us price the work.

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.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How much does the work cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

When to call us in Lydd-on-Sea

Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Typical triggers for a call:

  • Torn sealant in brick or block movement joints
  • Leaks through car park deck joints onto the level below
  • Expansion joints filled with dirt and stones
  • Arrises breaking up along floor joints

For a school such as Greatstone Primary School, playground and building joints can be done in the holidays.

  • What the guarantee covers, and for how long
