Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure ventilation in wet areas is switched on and working
- Add sealant to the planned maintenance inspection list
- Look at the sealant around anything that has been moved or replaced
Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.
Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.
Sealant specialists in Lochboisdale
Sealant joints are easy to overlook until one lets water in, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in Lochboisdale. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have untidy joints in a reception, shop floor or lobby and wall and floor joints that have lost their seal, we can help. Most enquiries from Lochboisdale start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Multi-site clients with buildings in and around Lochboisdale can put several sites on one programme, with one quote format and one point of contact.
Around smaller places such as Lochboisdale, the commercial buildings tend to be hospitality, local shops, schools, health centres and converted rural buildings. Their kitchens, washrooms and window perimeters all need joints that keep water out.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What the job involves on each surface
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.
Sealant on show in Lochboisdale’s commercial buildings
Lochboisdale lies within about 1 mile of the sea. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are usually where failed joints show first. For an island location such as Lochboisdale, work is planned around ferry crossings and the weather. A complete list with photographs means one crossing, not two.
Whatever the building in Lochboisdale, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Why deal with it now?
Reactive resealing, a leak at a time, tends to cost more overall than a plan. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Lochboisdale, a repair visit takes planning, so it’s better to act early.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Your questions answered
Do you offer colour-matched sealant for buildings in Lochboisdale?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
Can you take on a job in Lochboisdale, on the island?
Yes. Islands are part of our area, Lochboisdale included. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Is the old sealant taken out first?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away and isn’t worth paying for.
What do you need from us to quote?
Send photos, drawings or a list of locations. Where we need to see it, we will arrange a site visit, then send a fixed quote.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. Travel to smaller Scottish places like Lochboisdale is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Faulty windows rather than failed perimeter sealant
- Leaks from pipework, wastes or valves (that’s plumbing)
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
What we seal
- Kitchen worktops and splashbacks
- Window and door perimeters
- External facade joints
- Washrooms and tea points
- Floor and threshold joints
- Movement joints in walls and floors

Signs you need commercial sealant contractors in Lochboisdale
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath. Getting back to a clean joint then means removing every layer.
It’s worth sending us details if you spot any of the following:
- Mouldy silicone around WCs, urinals and vanity tops
- Weathered facade sealant that no longer flexes
- Frame mastic that has hardened and come away from the wall
- Gaps behind commercial kitchen worktops and sinks
Refits at hotels like Lochboisdale Hotel (to the north-east of Lochboisdale) bring joints at vanity tops, bars and reception desks that guests see every day.
