Mastic sealing for commercial buildings in Dunnet
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you have occupiers reporting cold air round windows and old repairs sealed over failed mastic, we can help, on communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks alike. Looking for mastic applicators who cover Dunnet? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places such as Dunnet, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic typically fails first.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

After the work
After handover, these steps help:
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
- Protect low-level joints in entrances
- Keep a record of when each building was resealed
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Leave it or put it right?
Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Dunnet, a repair visit takes planning, so it’s better to act early.
Pricing mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Signs you need mastic sealing in Dunnet
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
If one of these sounds familiar, it’s time for a closer look:
- Window mastic that has split and shrunk
- Leaks at window and door perimeters
- Draughts at frames across a block
- No planned programme for sealant
Churches, halls and community buildings such as Dunnet Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions we are asked in Dunnet
Can one quote cover a number of our buildings near Dunnet?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Our building in Dunnet is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
How many days will you need on site?
It depends on the scope, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
What affects the price in Dunnet
Each job is priced on its own details. The main factors are:
- The product specified
- Backing rod, priming and other preparation
- Whether the work must be split into stages
- Location, for remote and island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- Your programme or deadline
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Travel to smaller Scottish places like Dunnet is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
