Commercial sealant contractors for commercial buildings in Gremista
Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. We look before we quote and tell you plainly if sealant won’t solve it, so nobody pays for a reseal that can’t hold. The enquiries we see most involve leaks that seem to come through a sealant line and sanitary sealant that has gone black and patchy, on washrooms and tea points, movement joints in walls and floors and kitchen worktops and splashbacks. Searching for sealant specialists in Gremista? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Quotes for commercial sealant in Gremista can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.
Around smaller places such as Gremista, 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Surface by surface
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Why act early in Gremista
Reactive resealing, a leak at a time, tends to cost more overall than a plan. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Around smaller places like Gremista, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

FAQs: Gremista
Our building in Gremista is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Gremista inside the area you cover, given it’s on an island?
Yes, Gremista is within the area we cover. We cover the whole of Scotland. We group island work where we can and plan around the crossings.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can one contractor look after sealant on all our buildings?
Yes, we can. Send a list of addresses and what’s needed at each, and we will put together a fixed quote and a sensible order of work.
Do you check for asbestos before removing sealant?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Water from a services leak rather than a joint
- Cracking that needs a structural engineer to look at it
- Faulty windows rather than failed perimeter sealant
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.
Surfaces we seal
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
- Window and door perimeters
- Floor and threshold joints
- Washrooms and tea points
- External facade joints
General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Shops, offices and hotels in and around Gremista
With the shore within about 1 mile, Gremista counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. The 3 miles around Gremista take in at least three named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it.
Refits at hotels like The Shetland Hotel (to the south of Gremista) bring joints at vanity tops, bars and reception desks that guests see every day. A business with units at Lower Black Hill Industrial Estate and Black Hill Industrial Estate needn’t use two contractors for its sealant. On estates like Lower Black Hill Industrial Estate (less than half a mile south-west of Gremista), the office and welfare end of each unit has its own sealant to maintain.
Gremista is about 1 mile north of Lerwick, in the Shetland Islands. We cover commercial sites throughout Gremista, whether it’s a single job or part of a planned programme. Our the Shetland Islands coverage takes in 63 places.
If you need commercial sealant contractors in ZE1, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Gremista Road, Arlanda Yard and Holmsgarth Brae or close by, send details and we will quote for sealant joints. Close to Gremista, our area also takes in Heogan (1 mile east), Lerwick (1 mile south), Sound (2 miles south), Gunnista (2 miles east) and Veensgarth (2 miles west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you speak to us on 01277 525 020 or email a schedule or drawings.
