Expansion joint sealing in Forth

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

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near Forth, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space

Quotes

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call 01277 525 020 or email drawings and photos.

Advice

About our expansion joint sealing in Forth

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. If you have new sealant over old, now failing and sealant peeling off one face of the joint, we can help, on precast concrete panel joints, cladding panel joints and car park decks and ramps alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Forth it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For outside joints near Forth, the Scottish weather sets the timetable: dry faces and the right temperature are essential. Internal floors can be done whenever suits the site.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Your questions answered

Is Forth too far out for you?

Not at all. Forth is within our area. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

What documents will you need to give us for a job in Forth?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Why has the sealant in our expansion joints split?

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.

Do you reseal car park expansion joints?

Yes. Tell us how the car park is used and which areas must stay open.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Expansion joint sealing in Forth: the local picture

Forth is in the east of Scotland, which is drier 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.

Around Forth, open joints collect water and debris, and the arrises are the next to go. In and around Forth, the right filler or sealant for each joint depends on the traffic and the movement it takes.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Put movement joints on the planned maintenance inspection round
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Note which joints were done, when, and with what
  • Check joints after long freezing spells

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, 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, which is what makes a joint last.

Quoting for work in Forth

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Any access equipment needed
  • Induction, permit and paperwork requirements

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • The site address and postcode
  • Any specification or named product
  • Your programme or deadline
  • The type of building and who uses it

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Proprietary pre-formed expansion joint systems
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
