About our external mastic in Inverkip

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. Common call-outs are for water getting into walls through failed joints and panel joints letting water in, on façade panels, joints between brick and frames and render & cladding joints.

External sealant needs dry surfaces, so outdoor work around Inverkip is planned around the weather. Let us know about access to every wall and roofline.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface

Copings and trims

Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.

Concrete and blockwork

Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.

What affects the cost of external mastic

There’s no set price list. What we look at:

  • Working hours on commercial sites
  • Access and height
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

What to tell us for a quote

You don’t need to know the technical terms. Just tell us:

  • If someone has resealed it before
  • The type of property
  • Roughly how big the job is
  • Access, such as stairs, a lift or height

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

Signs you need external mastic in Inverkip

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.

Common reasons people contact us include:

  • Failed sealant between panels on a façade
  • Joints where the bead has come unstuck
  • Plants rooting in failed movement joints
  • Rigid filler in a joint that should flex

Rented homes near Inverkip station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What your quote should include

  • How the surfaces are prepared before sealing
  • How hidden problems are handled
  • What the cure time is
  • What product goes in the joint

10 questions to ask before you book

What we cannot put right

New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cracked brickwork or render that needs a builder or plasterer
  • Subsidence or other structural problems

Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Where we work in Inverkip

Why it’s worth doing now in Inverkip

Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a place like Inverkip, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

The process

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Around Inverkip, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. The old mastic and anything lodged in the joint is removed.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Mention any tricky access
  • Tell us if parking is tricky
  • Tell us about any water getting in

Walls and rooflines in Inverkip

Inverkip is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Ardgowan House (about 0.6 miles north) are a reminder that the area around Inverkip has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

For an older house near a landmark such as Inverkip Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Inverkip is about 4 miles south-west of Greenock, in Inverclyde. Jobs in Inverkip get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee.

FAQs for Inverkip

Will you come out to Inverkip?

Yes, Inverkip is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

I let a flat near Inverkip station. Can you help?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

How long does external mastic take?

As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.

Can a movement joint be filled with mortar?

No. Cement or mortar can’t stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
