Sites and facades in and around Lochmaddy

Lochmaddy lies within about 1 mile of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Building work in Lochmaddy comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. We seal to the specification that sits behind the warrant.

Sites around Lochmaddy get mastic sealed to the drawings and the programme, nothing improvised.

Lochmaddy (Gaelic: Loch nam Madadh) is in Na h-Eileanan Siar. We cover Lochmaddy and the rest of Na h-Eileanan Siar, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 87 places in Na h-Eileanan Siar, large and small.

If you need construction mastic in HS6, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Sites close to Lochmaddy are covered too, including Clachan Shannda (5 miles north-west), Locheport (6 miles south-west), Ruisgarry (8 miles north), Claddach Kirkibost (9 miles west) and Leverburgh (12 miles north-east). Where a site is remote or on an island, travel and materials need planning ahead.

Construction mastic in Lochmaddy, done properly

Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas. That keeps the work right first time and saves rework. We work on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions, and the usual reasons a site gets in touch are frame gaps too wide for sealant alone and existing joints on a refurb that need cutting out and resealing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lochmaddy it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In smaller places such as Lochmaddy, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Travel to smaller Scottish places like Lochmaddy is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We price from the drawings, specification and programme you send.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Quotes

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

How the job changes by surface

Kitchens and utility areas

Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Oversized gaps that need packing or adjustment by others
  • Joints damaged after sign-off by following trades
  • Glazing units that are cracked or misted

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think.

Where we work in Lochmaddy

FAQs: Lochmaddy

Will you travel to Lochmaddy on the island?

Yes. Islands are part of our area, Lochmaddy included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Can the mastic package for our job in Lochmaddy follow the site programme?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What we are called out for in Lochmaddy

Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

Typical triggers for a call:

  • A long mastic snag list close to completion
  • Sealant knocked or painted over by other trades
  • Early adhesion failures on new external joints
  • Oversized or tapered gaps around new frames

Work at a hotel such as Lochmaddy Hotel, 0.7 miles south-east of Lochmaddy, tends to be programmed around bookings, mastic included.

What your quote should include

  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

Quoting for work in Lochmaddy

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

  • The total length or number of joints
  • Phasing around occupants
  • The size and state of each joint
  • Travel to remote or island sites

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • A wide shot and a close-up of the area
  • The product your specification calls for
  • Asbestos survey details if the building is older
  • Any dates the work must fit around

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or use the quote form.
