Questions about Gatehouse of Fleet

Will our site in Gatehouse of Fleet 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. Tell us which hours and entrances we can use and we will plan from there.

Does the sea air around Gatehouse of Fleet change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Which product is best for expansion joints?

Movement capability matters most as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How we handle expansion joint sealing in Gatehouse of Fleet

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on car park decks and ramps, blockwork control joints and cladding panel joints, and what we’re called in for most is leaks through car park deck joints onto the level below and previous reseals laid over old sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Gatehouse of Fleet it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Gatehouse of Fleet is planned so the work is done in one trip where possible. Photos, approximate widths and what uses the floor help us bring the right materials.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Changing the joint layout or spacing of a structure
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Waterproofing layers buried beneath the sealant

Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly before you book.

Surfaces we seal

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

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Tell us who will meet us and how to get in at your building near Gatehouse of Fleet. That goes into the plan alongside the quote.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Send any specification or drawings in advance

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or use the quote form with what you know.

Expansion joint sealing around Gatehouse of Fleet: how the place shapes the job

Gatehouse of Fleet sits close to the coast, within about 2 miles. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster.

Outside joints are sealed in dry spells, so dates have some give.
