How we handle floor joint sealing in Nis

Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant so water and dirt cannot get in. Typical jobs include gaps at thresholds between rooms and gaps opening between the floor and skirting, across concrete floor joints, wet room & bathroom floors and skirting boards.

Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Don’t paint over silicone
  • Get cracks along tile grout lines looked at early
  • Lift furniture rather than dragging it across joints
  • Avoid sloshing water against skirting

Keep heavy furniture from dragging across the joints. Dragging can tear the bead.

In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.

What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Movement too big for a sealant joint
  • Cracked or broken concrete slabs
  • Failed waterproofing under a wet room floor

If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

What floor joint sealing looks like in Nis

Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

Around Nis, as everywhere, floor joint sealing is only as good as the preparation behind it. For site and facilities teams at buildings such as Lionel School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Nis (Gaelic: Ness) is in Na h-Eileanan Siar. We carry out floor joint sealing for householders, landlords and businesses in Nis. Across Na h-Eileanan Siar, we cover 87 places, and Nis is one of them.

Here we cover the HS2 postcode area for floor joint sealing. We also cover the places around Nis: Ness (1 mile south), Lionel (1 mile north-east), Cross (1 mile west), Lìonal (1 mile north) and Sgiogarstaigh (1 mile east). If you’re somewhere remote, a little more planning is needed.

Leave it or put it right?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now. Around Nis, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Doing several joints on one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.

The process

You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a morning or an afternoon for most homes in most cases. Somewhere like Nis may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any previous sealing or DIY attempts

What the job involves on each surface

Concrete floor joints

Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.

Wet room and bathroom floors

Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Questions from Nis

Do you cover smaller places like Nis?

Yes. Nis is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.

Is there a guarantee on floor joint sealing in Nis?

All our work, in Nis and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

How long does the job take?

A typical job takes a few hours, depending on the length of joint. We’ll confirm how long when we quote.

Do you work on commercial floors?

Yes. Concrete floor joints in warehouses and units are part of our work. We will talk through the traffic and choose a sealant suited to it.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

Why not just use caulk?

Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.
