About our remedial sealant in Niddrie Mains

Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that’s what we find, we will tell you rather than reseal something that will not fix it. If you’re dealing with mould trapped under a layer of silicone and movement joints that have split or pulled away, we can help, on failed movement joints, shrunken worktop sealant and botched or over-sealed joints alike.

In Scotland’s cities, including the area around Niddrie Mains, many older flats had their bathrooms added into small rooms later on. Space is tight and ventilation can be poor, which is hard on sealant and grout.

There’s a 12-month guarantee on every job.

DIY versus a professional finish

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Do you need remedial sealant in Niddrie Mains?

Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.

People generally contact us after spotting something like this:

  • Black mould underneath the bead
  • Wide, uneven beads that look worse than the old ones
  • Sealant that came away because the surface wasn’t prepared
  • Floor or wall movement joints that have failed

For site and facilities teams at buildings such as Castlebrae Community High School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

The process

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. In a city area like Niddrie Mains, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. Finally we finish the joint and talk you through what we found.

Before we arrive

  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts
  • Let us know about stairs, lifts or work at height

Landlords, agents and businesses in Niddrie Mains

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

We also work for property managers and facilities teams in Niddrie Mains and across Edinburgh. Several sites can be quoted together.

Why it’s worth doing now in Niddrie Mains

Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it, and the joint treated and dried before resealing. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.

What you get with us

  • 12-month guarantee on every job
  • Arbo and Everbuild products
  • White, clear, grey or coloured to suit, where the product allows
  • Sealant colour chosen to suit

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.

What happens if the problem is the tray or the plumbing?

We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

Are you insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Bathrooms and kitchens in Niddrie Mains

Niddrie Mains is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.

Letting a property close to Brunstane station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
