How we handle construction mastic in Port Mholair
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Port Mholair, send drawings and the specification through our quote form. We work on internal decorators’ caulk, cladding and panel joints and brick and block movement joints, and what we are called in for most is a mastic package split between trades with no clear owner and internal caulk splitting as the building dries out. Searching for sealant specialists in Port Mholair? We have been sealing commercial buildings since 2005.
In smaller places such as Port Mholair, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Port Mholair
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
Clients normally get in touch after noticing something like this:
- Cracks opening in caulked internal joints
- Mastic snags holding up handover
- Early adhesion failures on new external joints
- Sealant knocked or painted over by other trades
School extensions, at buildings such as Aird Primary School, typically run to the summer holidays, mastic included.
Before you book anyone
- How the joint faces will be prepared and primed
- Their pre-qualification and accreditations
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?

What else we do in Port Mholair
Questions we are asked in Port Mholair
Does the sea air around Port Mholair change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can the mastic package for our job in Port Mholair 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.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.
Does weather affect external mastic work?
External mastic depends on conditions: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What the job involves on each surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.
Commercial clients in Port Mholair
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Port Mholair can sit alongside others in a wider programme across Na h-Eileanan Siar.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
After the work
Regular inspection catches problems early. In particular:
- Keep product details for future maintenance
- Plan external elevations with the weather in mind
- Keep finished joints away from paint, plaster and scrapers
- Share drawings and the specification as soon as possible
Any damage after we have finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out and keeps handover on track.

Island jobs, Port Mholair among them, are planned around the ferry and the forecast. With drawings and the programme in hand, the whole mastic package comes with us.
On any site in or around Port Mholair, the mastic follows the specification and the programme.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Port Mholair, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Advice
Leave it or put it right?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. For buildings near Port Mholair, dealing with all the failing joints at once saves return trips. Send photographs and we’ll quote for everything together.
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.
