Expansion joint sealing for Charter Alley sites

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

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Leaks coming from the membrane rather than the joint seal
  • Concrete or masonry repairs along the arrises
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

Expansion joint sealing in Charter Alley, done properly

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you have rain penetration at brick or block movement joints and weathered movement joint sealant that no longer flexes, we can help. Most enquiries from Charter Alley start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Jobs around smaller places like Charter Alley 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Inspect movement joints alongside other routine building checks
  • Look over external and deck joints after a hard winter
  • Clear dirt from joint lines during routine cleaning
  • Keep scrapers and ploughs from dragging across joint sealant

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.

On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

FAQs: Charter Alley

Is a smaller place like Charter Alley outside your area?

Not at all. Charter Alley is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Is a hospital such as Parklands Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it.

What guarantee do you give on joint sealing?

The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Charter Alley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  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 staff and tenants when we’ll be in
  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000

Related advice

Do you need expansion joint sealing in Charter Alley?

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.

Any of the following is a good reason to get the joints checked over:

  • Leaks through car park deck joints onto the level below
  • Debris jammed in movement joints
  • Water getting into the wall through a failed joint
  • Hardened, cracked sealant on exposed facades

Schools like The Priory Primary School often have long brick elevations with movement joints that age quietly.

Questions to ask before you book

  • Who will actually carry out the work
  • The named product and why it was chosen
  • Their pre-qualification and accreditations
  • Their approach to joint depth and backing

Cost factors for movement joints

Quotes vary with the job. It mainly depends on:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Distance, for remote addresses

A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • The asbestos register, for older buildings
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send photos by email.

Slabs, ramps and loading bays in Charter Alley

At about 47 miles from central London, Charter Alley is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Charter Alley included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Hospitals like Parklands Hospital, 2.7 miles south-east of Charter Alley, have multi-storey or surface car parks whose joints carry vehicles round the clock. For buildings at a park such as Berry Court Business Park, which lies north-east of Charter Alley, brick and panel movement joints are easy to forget until one leaks.

Charter Alley is about 3 miles south of Tadley, in Hampshire. Across the RG26 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Charter Alley is one of 723 places in Hampshire on our list. There’s a separate page for Reading, about 12 miles away.

Anyone looking for expansion joint sealing in RG26 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

We also cover Ramsdell (1 mile west), West Heath (1 mile north-west), Pamber End (1 mile north-east), Monk Sherborne (1 mile south-east) and Salters Heath (1 mile east).
