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

Mastic sealing in Innermessan, done properly

For blocks and buildings in Innermessan and across Dumfries and Galloway, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you have mastic failing across several blocks on an estate and old repairs sealed over failed mastic, we can help. Looking for mastic applicators who cover Innermessan? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

For buildings around Innermessan, we group the work to keep travel and visits down. A list of addresses and photos lets us quote for them together.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Innermessan, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Make sure the joints can be reached

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email a schedule or drawings.

Common problems we fix in Innermessan

Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

Common reasons buildings call us in:

  • Complaints coming in block by block
  • Water getting in round frames after rain
  • Worn sealant at communal door frames
  • Old repairs sealed over failed mastic

Property owners at sites such as Castle Kennedy Industrial Estate, 2.4 miles to the south-west of Innermessan, can have mastic renewed between lettings.

Before you book anyone

  • Who will actually carry out the work
  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Surface by surface

Tenement and older buildings

Stone needs a neutral-cure product, so we pick a grade that won’t mark it.

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.

Cost factors for mastic joints

These are the things that shape the price:

  • Removal of failed or old sealant
  • Joint width, depth and condition
  • Whether the work must be split into stages
  • Access and working height

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • When you need the work done
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email the details over with what you know.

Commercial clients in Innermessan

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on everything from one building to a spread of sites around Innermessan. Several sites can go on one quote, which keeps the paperwork simple.

Innermessan: questions and answers

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

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Innermessan off your patch?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

Can you reseal a whole block or estate?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Failed window or door frames, which need a window contractor
  • Leaks from above rather than through a joint
  • Glazing that needs replacing

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

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

Frames, entrances and external joints in Innermessan

Innermessan 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; plan inspections around that. Innermessan is on Scotland’s wetter western side. The most exposed elevations need checking most often. Programmes allow for wet days.
