Expansion joint sealing for commercial buildings in Smailholm

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. Most enquiries involve brittle, chalky sealant on external joints and arrises breaking up along floor joints, on blockwork control joints, precast concrete panel joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Smailholm is the same: the right product in a properly prepared joint.

Weather windows decide external joint work around a place like Smailholm: sealant needs a dry joint and a temperature within its range, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sets the cost

Before we quote, we look at:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

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 we’ll put a fixed figure on it.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • The postcode of the building

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

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Damaged metal nosings or cover plates over a joint
  • A joint that has to be widened or re-detailed before it can work
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.

Expansion joint sealing in Smailholm: the local picture

Smailholm is in the east of Scotland, which is drier than the west. Frost and winter road salt still work into open joints in car parks and yards. Sealing them in drier months limits winter damage.

Hospital campuses such as Kelso Hospital, 4.9 miles east of Smailholm, grow in stages, leaving movement joints wherever new blocks meet old. For floors and slabs around Smailholm, the product is chosen for the traffic and the movement at each joint.

Surface by surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.

Your questions answered

Does a site in Smailholm have to shut while its joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Is a smaller place like Smailholm outside your area?

No. Places such as Smailholm are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

Do you take on small jobs?

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

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Include photos or drawings if you have them.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you guarantee expansion joint work?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Note which joints were done, when, and with what
  • Act on the first tear or lifting edge rather than waiting
  • Keep stones and debris out of open joint lines
  • Look over external and deck joints after a hard winter

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs near Smailholm are often grouped with others in the same area. Tell us how flexible your dates are.

  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. We strip out the old seal and prepare the faces, 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. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached
  • Point out any areas we must not close

Should maintenance staff do it?

Redoing a failed joint typically 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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
