Construction mastic for businesses in Mail
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
How we handle construction mastic in Mail
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short. If you have internal caulk splitting as the building dries out and frame perimeters left unsealed or poorly sealed, we can help. Searching for sealant specialists in Mail? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Mail that means watching the forecast. We build some give into the plan and agree it with the site manager.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
For the best life from the joints:
- Don’t force external sealing on a damp or frosty day
- Record the products used in the O&M file
- Ask for joint and product checks before the package is urgent
- Put any product change through the designer first
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
What else we do in Mail
Building owners, agents and FMs in Mail
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Mail. One quote can cover more than one site, which keeps the paperwork simple.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Working within restricted access windows
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- The product specified
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- What the building is and how it’s used
- The product your specification calls for
- Any dates the work must fit around
- Where the site is, with the postcode
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email the details over.
Common questions from Mail clients
Does a coastal location like Mail affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can the mastic package for our job in Mail follow the site programme?
Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Does weather affect external mastic work?
External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing.
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.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Mastic packages on Mail sites
Mail lies within about 1 mile of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Mail is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team.
Around Mail, as anywhere, a facade joint depends on its sizing, backing rod and preparation. For contractors building in or near Mail, we seal to the drawings, the specification and the programme.
Mail is about 9 miles south of Lerwick, in the Shetland Islands. We cover Mail, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across the Shetland Islands, 63 places are covered, including Mail.
Commercial sites across ZE2 are covered. Nearby places we also cover include Bremirehoull (1 mile north), Cunningsburgh (1 mile north), Aithsetter (2 miles north-east), Sandwick (2 miles south) and Hoswick (3 miles south) for mastic packages. Further afield, our area takes in Lerwick (9 miles north), Sound (8 miles north) and Scalloway (7 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.
What’s near Mail
Open spaces near Mail include Loch of Fladdabister.
What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes whatever the programme allows, since the work follows the trades as areas are released, and our waste is bagged and taken away as we go. For work around Mail, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
