Expansion joint sealing in Walter's Green

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

Expansion joint sealing in Walter's Green, done properly

If you need expansion joint sealing in Walter's Green, start with photos and joint lengths. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, phone 01277 525 020 or email us. We work on blockwork control joints, cladding panel joints and brickwork movement joints, and the failures we are asked to look at most are joints packed with grit and debris and joints where the bead has lost adhesion. Facilities teams, main contractors and managing agents in Walter's Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Jobs around smaller places like Walter's Green are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Our workmanship is guaranteed for 12 months, in Walter's Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

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. Halls, stores and units around places like Walter's Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • A Constructionline member, so easy to vet

See what affects the cost and our accreditations and insurance.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Keep product details with the building records for the next reseal
  • Plan racking layouts so feet don’t land on a joint
  • Put movement joints on the planned maintenance inspection round
  • Report split or peeling joint sealant early

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Traffic, movement and joints around Walter's Green

Walter's Green is about 27 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.

Campuses like Canterbury Christ Church University - Salomons, 3.5 miles east of Walter's Green, mix old and new buildings, with movement joints wherever they meet. For a school such as Fordcombe Church of England Primary School, playground and building joints can be done in the holidays.

Building owners, agents and FMs in Walter's Green

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Signs you need expansion joint sealing in Walter's Green

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.

These are often picked up first by site or facilities staff:

  • New sealant over old, now failing
  • Chipped joint edges on forklift routes
  • Expansion joints split through the centre of the bead
  • Car park joints leaking onto vehicles below

Large sites such as Kent and Sussex Hospital (to the east of Walter's Green) have car parks, service roads and long elevations with movement joints in brick and panels.

What your quote should include

  • What the guarantee covers, and for how long
  • Who will actually carry out the work
  • Can the work be phased to keep areas open?
  • The named product and why it was chosen

Questions to ask before you appoint anyone

Diagnose, treat, sign off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Walter's Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Move anything stored against the joints
  • Tell staff and tenants when we will be in
  • Explain the parking and delivery arrangements

Questions about Walter's Green

Will you take on work at estates like Speldhurst Business Park, close to Walter's Green?

Yes. Our area takes in Walter's Green and its surroundings, with estates and business parks such as Speldhurst Business Park included. A few photographs and the unit address let us price the work.

Can you work on a hospital site such as Kent and Sussex Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
