About our mastic sealing in Grimness
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on external wall and movement joints, shopfronts below residential blocks and balcony and threshold joints, and the usual reasons a site gets in touch are window mastic that has split and shrunk and the same joint failures repeated across a portfolio. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Grimness is the same: the right product in a properly prepared joint.
Travel to smaller places like Grimness is planned so several buildings can be done on one trip. A list of addresses and photographs lets us quote for them together.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If you’re not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
What we seal
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints

Questions we’re asked in Grimness
Do you take on block-wide or estate-wide mastic work in Grimness?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Our building in Grimness is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How do you reach windows on upper floors?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Mastic sealing around Grimness: what changes locally
With the shore within about 1 mile, Grimness counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Grimness is on Scotland’s drier eastern side. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. Programmes allow for that
Around Grimness, a planned programme renews failed mastic across a building or estate in one go. For a building around Grimness, a look at every elevation first shows which joints need renewing now and which can wait.
Grimness is about 11 miles south of Kirkwall, in the Orkney Islands. Across the KW17 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Grimness is one of 51 places in the Orkney Islands on our list for mastic joints.
Anyone looking for mastic sealing in KW17 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Grimness sits on or close to the B9044, which helps when planning parking and deliveries for the job. Just outside Grimness, we also work in Burray Village (1 mile north), St Margaret's Hope (2 miles west), Widewall (3 miles south-west), St Mary's (5 miles north) and Upper Sanday (7 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call the office on 01277 525 020 or email the details over.

Surface by surface
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. How each joint is reached is agreed at quote stage.
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Encourage occupiers to report problems at frames
- Log resealing dates block by block
- List the paperwork your organisation requires when you send details
- Share the asbestos register when you send details
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Why deal with it now?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. For buildings near Grimness, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Access often affects the price as much as the sealing: 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.
