About our glazing silicone in Castlebay

We work across Castlebay on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. Common call-outs are for water running down inside the glass and mouldy sealant around glass panels, across conservatory frames, glass-to-frame joints and rooflights.

Outdoor sealant needs a dry surface, so window work around Castlebay is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.

Our work is backed for twelve months.

The process

At the end, we look at the finished work together and explain the cure time. The visit itself generally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the size of the job. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.

  1. First we agree the joints to be done.
  2. Old sealant is removed from the glass and frame.
  3. The surfaces are cleaned with a suitable solvent.
  4. We apply and tool the new silicone.
  5. We inspect the work and test it where we can.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Mention any sign-in or site rules at work premises

How we quote for glazing silicone

For a quick quote, just ask. The main things that affect it are:

  • Working hours on commercial sites
  • Whether the work is at height
  • Mould in or behind the old joints
  • The number and length of the joints

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What we need to know

When you call or email, these details help:

  • Any previous sealing or DIY work
  • The type of property
  • Pictures of the joints, sent by email
  • Where the job is, and your postcode

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, send an email to info@mrmastic.co.uk.

Do you need glazing silicone in Castlebay?

On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.

It’s worth asking for a quote if you see:

  • Water escaping where a screen meets the wall
  • Silicone pulling away from the glass
  • Leaks where conservatory glass meets the frame
  • Stained, discoloured glazing silicone

In the older streets around Church of our Lady, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Before booking anyone

  • Which sealant they’ll use, and why
  • What the cure time is
  • The length of the guarantee
  • Whether VAT is included

Choosing a sealant specialist

Glazing silicone in Castlebay: local notes

Castlebay is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so give us as much notice as you can.

If you look after a building such as Castlebay Community School, larger buildings have plenty of frames, and the mastic around each one ages.

Castlebay is in Na h-Eileanan Siar. Whether you are in the middle of Castlebay or further out, glazing silicone is available for homes and businesses alike, from flats and houses to offices and hotels. Castlebay is one of 87 places in Na h-Eileanan Siar where we work for glazing silicone.

Work in HS9 is quoted and booked the same way as anywhere else. Local streets include Pier Road and Rathad na Horgh. Other places close to Castlebay include Leideag (1 mile south-east), Bàgh a'Chaisteil (1 mile west), Ceann Tangabhal (1 mile north-west), Brèibhig (1 mile east) and Cuidhir (3 miles north). Remote and island addresses need a little more planning, so please mention your location when you send an email to info@mrmastic.co.uk.

Surface by surface

Glass-to-frame joints

Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.

Glass-to-glass joints

Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

FAQs for Castlebay

Is Castlebay within the area you cover?

Yes. Castlebay 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. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Castlebay for glazing silicone?

Yes, Castlebay is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.

Are you ARBOMaster approved?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you fix a leaking conservatory?

If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we will tell you.

Why not top up the existing silicone?

Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

How long does the job take?

As a guide, most jobs take a few hours for most jobs. Bigger jobs take longer, and we’ll say how long yours will take.

Why deal with it now?

Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.
