Need mastic sealing in Marybank?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What affects the price in Marybank

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

  • The product specified
  • Removal of failed or old sealant
  • The size and state of each joint
  • Access and working height

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The postcode of the building
  • The asbestos register, for older buildings
  • Any specification or named product
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

About our mastic sealing in Marybank

Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and the failures we’re asked to look at most are communal area joints that look neglected and the same joint failures repeated across a portfolio. Whoever orders the work in Marybank, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Outside mastic in Scotland needs dry joints and the right temperature, so work around Marybank is planned with the forecast. We agree a window with some flexibility.

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

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Track which buildings were done and when
  • Group repairs into a planned programme
  • List the paperwork your organisation requires when you send details
  • Reduce knocks to communal area joints

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Asbestos-containing sealant, which we don’t remove
  • Leaks from above rather than through a joint
  • Masonry that has broken away beside the joint

If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.

Joints and surfaces we work on

  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks
  • External wall and movement joints

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Tell us who will meet us and how to get in at your building near Marybank. We will confirm the plan with the fixed quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Have the specification and drawings to hand

Mastic sealing in Marybank: the local picture

Marybank lies within about 1 mile of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Work on Marybank has to fit the ferry timetable and the forecast. We group island buildings so each crossing covers as much as possible.

Around Marybank, a planned programme renews failed mastic across a building or estate in one go. For owners of several units at places like Marybank Industrial Estate, under half a mile to the east of Marybank, one programme can deal with frame and external mastic across the lot.

Marybank is about 1 mile west of Stornoway, in Na h-Eileanan Siar. Businesses, contractors and managing agents in Marybank can call on us for mastic joints, as part of our coverage of Na h-Eileanan Siar. Marybank is one of 87 places we cover in Na h-Eileanan Siar for mastic joints.

Business premises anywhere in HS2 and HS1 are within our area. For a building on Bennadrove Road, Airidhean Ur and Macgregor Park or nearby, we can quote for mastic joints. Close to Marybank, our area also takes in Laxdale (1 mile north-east), Stornoway (1 mile east), Newmarket (1 mile north-east), Plasterfield (2 miles east) and Sandwick (2 miles east). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Surface by surface

Estate-wide resealing programmes

Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.

FAQs: Marybank

Will you travel to Marybank on the island?

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

Does the sea air around Marybank change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

How do you reach windows on upper floors?

Every block is different. We agree access with you at quote stage so the fixed quote reflects it.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What if the old mastic contains asbestos?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
