About our facade sealing in Lonmore

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Most enquiries involve cladding panel joints that have opened up and air leaks through failed facade joints, on window and door perimeters, stone and brick facade joints and coping and flashing joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lonmore, preparation and product choice get the time they need.

For a site around Lonmore, we plan the mastic in as few trips as the programme allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Around smaller places like Lonmore, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Colours chosen to suit frames, cladding or finishes where possible

What the job involves on each surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in, tooled to shed water.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

Your questions answered

Is Lonmore too far out for you?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.

Can being near the sea in Lonmore affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months on every job.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Keeping the joints sound

To get the most from the new sealant:

  • Share access with other external trades
  • Keep the sealant details on the building file
  • Investigate damp beside windows promptly
  • Avoid patch repairs on failed facade joints

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Arranging specialist high-level access, which is planned with the client
  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Stone and brick facade joints
  • Cladding panel joints
  • Shopfront frames

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building near Lonmore, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Share your working hours and any access restrictions
  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints

What we are called out for in Lonmore

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

It’s worth sending us details if you spot any of the following:

  • Sealant pulling away from frames or panels
  • Failed seals around shopfront and entrance frames
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters

For contractors building in or near Lonmore, we seal to the drawings, the specification and the programme.

Before you book anyone

  • The terms of the workmanship guarantee
  • Proof of insurance
  • Whether their applicators hold CSCS cards
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Building and refurbishing in Lonmore

Lonmore is within about 2 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Building work in Lonmore comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.

Hotels like Dunvegan Hotel, 1.2 miles north-west of Lonmore, rarely close for long, so refurbishment mastic is phased floor by floor.

Lonmore is in Highland. Any commercial site in Lonmore is covered. Our Highland coverage takes in 256 places.

Anyone looking for facade sealing in IV55 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Lonmore, we cover Dunvegan (1 mile north-west), Kilmuir (1 mile north-west), Colbost (3 miles west), An t-Aodann Ban (6 miles north-east) and Coillore (8 miles south-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Near you in Lonmore

Well-known places in the area include Dunvegan Castle (2 miles north-west) and Giant Angus Macaskill Museum (1 mile north-west). The countryside around Lonmore includes MacLeod's Table.
