Expansion joint sealing in Holmbury St Mary

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why deal with it now?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. One visit to deal with every failing joint makes more sense than several trips to a place like Holmbury St Mary, rather than one at a time. Photos of every joint help us quote for the whole job.

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.

What you get with us

  • Clear, fixed quotes
  • Public liability insurance in place
  • Over 20 years of commercial sealing
  • Workmanship guaranteed for 12 months

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Check joints after long freezing spells
  • Keep product details with the building records for the next reseal
  • Act on the first tear or lifting edge rather than waiting
  • Keep racking legs and heavy point loads off floor joints

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.

Expansion joint sealing around Holmbury St Mary: what changes locally

Central London is about 25 miles from Holmbury St Mary. Warehousing clusters around the motorways that ring and radiate from London. Holmbury St Mary is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

In a school such as Belmont Prep School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For floors and slabs around Holmbury St Mary, the product is chosen for the traffic and the movement at each joint.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Holmbury St Mary are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  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.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Proprietary pre-formed expansion joint systems
  • Changing the joint layout or spacing of a structure
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Surfaces we seal

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

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Holmbury St Mary can form part of a wider programme.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Questions we are asked in Holmbury St Mary

What paperwork can you provide for a job in Holmbury St Mary?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Holmbury St Mary too far out for you?

Not at all. Holmbury St Mary is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you seal joints in cold or wet weather?

Sealing onto a damp surface leads to adhesion failure, so external work waits for suitable conditions. The work is simply moved to the next suitable day.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can weather delay the job?

It can, when the joints are outside. 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.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
