How we handle mastic sealing in Cross

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Cross carry our 12-month guarantee. We work on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks, and what we’re called in for most is repeated reactive repairs to the same buildings and worn sealant at communal door frames. A specialist sealant contractor works differently from a general builder: on jobs in Cross, preparation and product choice get the time they need.

Travel to smaller places like Cross is planned so several buildings can be done on one trip. Send addresses and photographs for a quote covering the batch.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What affects the price in Cross

What shapes the price:

  • Quantities, in metres or numbers
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Details that help us quote

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

  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • The site address and postcode

To get a fixed quote, give us a call on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

Blocks and managed buildings in Cross

Cross is within about 2 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. For an island location such as Cross, work is planned around ferry crossings and the weather. We group island buildings so each crossing covers as much as possible.

Owners near Cross can renew frame and external mastic block by block on one programme.

Cross (Gaelic: Cros) is in Na h-Eileanan Siar. Anywhere in HS2, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Na h-Eileanan Siar, 87 places are covered, including Cross.

Commercial sites across HS2 are covered. If your site is on Rathad Chros-Sgiogarstaigh, Back Street and New Street or close by, send details and we’ll quote for mastic joints. We also cover North Dell (1 mile west), Nis (1 mile east), Ness (1 mile east), Lionel (2 miles north-east) and Lìonal (2 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

What’s near Cross

Nearby you will also find Dell Mill (less than half a mile west). For a walk, there’s Loch Langavat.

What we are called out for in Cross

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.

Site and facilities staff are often the first to spot these:

  • Water getting in round frames after rain
  • Estate-wide sealant that is simply worn out
  • Draughts at frames across a block
  • No planned programme for sealant

If you’re responsible for a building such as Church of Scotland, frame and door mastic needs the same attention as any other property.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Questions about Cross

Do you work on the island where Cross is?

Yes. Islands are part of our area, Cross included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Can you quote for mastic across several buildings in and around Cross?

Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.

Can you take on resealing for a block portfolio?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

How long do sealant joints last?

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.

Can people stay in the building while you reseal?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How the job changes by surface

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

External movement joints

Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Building owners, agents and FMs in Cross

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Cross, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work
