How we handle expansion joint sealing in Howt Green

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. Site teams most often ask us about brittle, chalky sealant on external joints and joints where the bead has lost adhesion, on podiums and floor movement joints, car park decks and ramps and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Howt Green is the same: the right product in a properly prepared joint.

Jobs around smaller places like Howt Green are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Work for main contractors and building owners

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Common questions from Howt Green clients

Can you take on a job at a hospital such as Sittingbourne Memorial Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Newington Enterprise Centre, near Howt Green?

Yes, sites like Newington Enterprise Centre are within our area, along with the rest of Howt Green. A few photos and the unit address let us price the work.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

What timescale should we allow for resealing expansion joints?

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, including any phasing.

Do you cover Howt Green?

Yes. We take on work across Howt Green.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If others near Howt Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  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. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we’re called out for in Howt Green

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Clients usually get in touch after noticing one or more of the following:

  • Debris jammed in movement joints
  • Chipped joint edges on forklift routes
  • Joints where the bead has lost adhesion
  • Damp inside where a wall movement joint has failed

For buildings at a park such as Newington Enterprise Centre (2.2 miles west of Howt Green), brick and panel movement joints are easy to forget until one leaks.

Warehouse floors and decks around Howt Green

Howt Green is within about 2 miles of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Howt Green lies roughly 36 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Another example is Newington Industrial Estate (3 miles west of Howt Green), where floors and yards would be done in stages around the occupiers. Hospital campuses such as Sittingbourne Memorial Hospital, 1.9 miles south of Howt Green, grow in stages, leaving movement joints wherever new blocks meet old.

Maintenance after handover

For the best life from the joints:

  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue
  • Keep racking legs and heavy point loads off floor joints
  • Look over external and deck joints after a hard winter

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can give us a call on 01277 525 020 or send photos by email and send a picture.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Older rural buildings around Howt Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
