Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Tarbert, a repair visit takes planning, so it’s better to act early.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Mastic sealing in Tarbert, done properly
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Tarbert carry our 12-month guarantee. Site teams most often ask us about old repairs sealed over failed mastic and failed external movement joints, on window and door perimeters on blocks, external wall and movement joints and communal entrances and stairwells. One point of contact handles commercial sealant work in Tarbert from the first photos to the final walk-round, whether it’s one building or several.
Around smaller places such as Tarbert, 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Frames, entrances and external joints in Tarbert
The sea is no more than about 1 mile from Tarbert. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The west of Scotland, where Tarbert is, gets more rain than the east. The weather side of a block usually needs attention first. Programmes allow for wet days.
Owners near Tarbert can renew frame and external mastic block by block on one programme. Wherever your building is in or near Tarbert, we look at the whole elevation before quoting, so you know what needs doing now.

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Asbestos-containing sealant, which we don’t remove
- Glazing that needs replacing
- Substrate edges that need repairing first
If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- The product specified
- Any access equipment needed
- How much existing material needs removing
- Joint width, depth and condition
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back
- When you need the work done
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or send details through our quote form.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Group repairs into a planned programme
- Check sealant joints during planned building inspections
- Log resealing dates block by block
- Look at the sunniest and most exposed elevations first
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Travel to smaller Scottish places like Tarbert is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Point out parking and an unloading spot
- Send your site hours and access windows
- Confirm the product named in the specification
