Construction mastic in Hamnavoe, done properly
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. Site teams most often ask us about sealant knocked or painted over by other trades and window and door perimeters that won’t pass inspection, across floor and skirting junctions, cladding and panel joints and internal decorators’ caulk. Facilities teams, main contractors and managing agents in Hamnavoe tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Hamnavoe that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
A 12-month guarantee applies to all our work in the Shetland Islands. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Common problems we fix in Hamnavoe
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Typical triggers for a call:
- Caulk cracking where joints are moving more than expected
- A mastic package split between trades with no clear owner
- New external sealant already peeling away
- Missed perimeter joints on a new elevation
A facade joint near Hamnavoe lasts when width, depth and backing are right, not just the finish.
What to look for in a quote
- How joint depth will be controlled
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- Their plan for phasing and protecting the area
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building near Hamnavoe, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

FAQs: Hamnavoe
Can the mastic package for our job in Hamnavoe follow the site programme?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can being near the sea in Hamnavoe affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you work plot by plot or floor by floor?
The programme sets the job. Tell us the sequence and we will plan applicators around it, sealing as areas become ready.
Can you work to our specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
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.
General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Contractors’ notes for Hamnavoe
With the shore within about 1 mile, Hamnavoe counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. For an island location such as Hamnavoe, work is planned around ferry crossings and the weather. Drawings and the programme let us bring every sealant, primer and backing rod the package needs.
For contractors building in or near Hamnavoe, we seal to the drawings, the specification and the programme.

Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference, especially externally. Where an alternative is genuinely suitable, we’ll say so. For buildings near Hamnavoe, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.
A quote for mastic packages depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Rework caused by others damaging completed areas
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
