Expansion joint sealing across Comiston

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

Leave it or put it right?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. In a Scottish city, access often needs scaffold, permits or factor approval, so it makes sense to renew every failing joint while it’s in place.

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Why choose Mastic Doctor in Comiston

How we handle expansion joint sealing in Comiston

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. If you are dealing with hardened, cracked sealant on exposed facades and rain penetration at brick or block movement joints, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Comiston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In Scottish cities, where newer extensions meet older stone buildings, movement joints take the difference. They need the right movement class and correct width and depth to last.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Expansion joint sealing in Comiston: the local picture

The 3 miles around Comiston take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. The east of Scotland, where Comiston is, gets less rain than the west. Frost and de-icing salt still find their way into open external joints. Resealing before the cold months helps protect the edges.

Parks like Blackford Business Park, 1.5 miles north-east of Comiston, combine paved areas, car parks and building elevations, each with joints that move. Another example is West Gorgie Park Industrial Estate, 1.8 miles to the north-west of Comiston, where floors and yards would be done in stages around the occupiers. In a school such as Firrhill High School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Comiston is about 2 miles south of Edinburgh, in Edinburgh. We send applicators to Comiston for movement joints. 174 places across Edinburgh fall within our area, Comiston among them.

Questions about Comiston

Will our site in Comiston have to close for joint sealing?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Do you cover business parks and estates near Comiston, such as Blackford Business Park?

Yes. Estates, retail parks and business parks around Comiston, Blackford Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is colour matching possible?

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

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Give us the access times and building rules for your premises in Comiston, so the work can be phased and areas kept in use.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  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. 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.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in

Related advice

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • How much there is to seal
  • How accessible the joints are
  • The site’s rules and procedures
  • Backing rod, priming and other preparation

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Any dates the work must fit around
  • The postcode of the building
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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.

After the work

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

  • Inspect exposed joints once the cold weather has passed
  • Keep product details with the building records for the next reseal
  • Reopen bays and walkways only after the stated cure time
  • Clear dirt from joint lines during routine cleaning

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
