About our mastic sealing in Ranfurly

Managing agents and housing associations usually need paperwork before anyone starts. 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, with public liability insurance. We work on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints, and the usual reasons a site gets in touch are a mix of products and colours from past repairs and open joints in brickwork or panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ranfurly is the same: the right product in a properly prepared joint.

In smaller Scottish places like Ranfurly, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic usually fails first.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When something else is needed

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

  • Glazing that needs replacing
  • Failed window or door frames, which need a window contractor
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

  • Shopfronts below residential blocks
  • Balcony and threshold joints

Looking after buildings in and around Ranfurly

Ranfurly is in the west of Scotland, the wetter side of the country. Exposed elevations on blocks take a soaking and their mastic shows it. We plan block programmes with the forecast in mind.

For agents with blocks near Milliken Park station, which lies south-east of Ranfurly, a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like Ranfurly Church of Scotland can bring frame and external mastic into a planned maintenance list.

Ranfurly is about 3 miles north-west of Johnstone, in Renfrewshire. We cover Ranfurly and the rest of Renfrewshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 23 places across Renfrewshire fall within our area, Ranfurly among them. We also cover Glasgow, around 12 miles from Ranfurly.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How much there is to seal
  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • What the building is and how it’s used
  • When you need the work done
  • Access details, including height
  • Any specification or named product

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Questions we are asked in Ranfurly

Is Ranfurly too far out for you?

No. Places such as Ranfurly are covered as much as the big towns. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.

Will you price a mastic programme across our Ranfurly portfolio?

Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. 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. If any flats or units need access, we’ll tell you in advance so it can be arranged.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Can you seal joints high up on a block?

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

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Maintenance after handover

Once the work is signed off, these steps help:

  • Avoid piecemeal callouts where you can
  • Make it easy for occupiers to report draughts
  • Prioritise elevations facing the weather
  • Have the asbestos survey to hand for older buildings

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.

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

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Where we can, we combine work around Ranfurly with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  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. We finish each building before moving to the next.

Before we start on site

  • Point out any areas we must not close
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Related advice

What happens if it’s left?

Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Around smaller places like Ranfurly, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

Pricing mastic joints depends on quantities, condition and access. Call for a quote.
