Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.
Why act early in Grimsay
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Grimsay before they leak.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

How the quote is worked out
These are the things that shape the price:
- Travel to remote or island sites
- Joint width, depth and condition
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- How the joints are reached, and at what height
- Where the site is, with the postcode
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email us.

What else we do in Grimsay
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Ask residents or tenants to report leaks and draughts early
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
- Share your contractor requirements early
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
Common questions from Grimsay clients
Our building in Grimsay is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you work on the island where Grimsay is?
Yes, Grimsay is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs near Grimsay are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.
- We check the asbestos register for older buildings and look at the joints.
- 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.
Before we start on site
- Have the specification and drawings to hand
- Flag any permit to work we’ll need
- Send asbestos survey details if the building is pre-2000

Block-wide mastic in Grimsay
The sea is no more than about 1 mile from Grimsay. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. Being in the west of Scotland, Grimsay gets more rain than eastern areas. The weather side of a block normally needs attention first. External work is booked for dry spells, with a little give in the dates.
Wherever your building is in or near Grimsay, we look at the whole elevation before quoting, so you know what needs doing now.
