Your questions about window mastic in Locheport
Do you cover Locheport for window mastic?
Yes. Our work covers the whole of Scotland, and Locheport is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Locheport within the area you cover?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Na h-Eileanan Siar.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Window mastic for homes and businesses in Locheport
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have cracked internal joints between frame and plaster and cracked or shrunken mastic around the frame, we can help, on aluminium frames, window sills and patio & French doors alike.
Outdoor sealant needs a dry surface, so window work around Locheport is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. Outside jobs in Locheport need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Advice
Quotes for window mastic in Locheport
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- Mould in or behind the old joints
- When we can work, for business premises
- The old material and how stubborn it is
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
To make quoting easier, let us know:
- Roughly how big the job is
- Whether it’s a home or a business
- What’s wrong with the joints now
- The address or postcode of the job
Every job is quoted individually, so start by telling us what you need. Simply drop us a line at info@mrmastic.co.uk and describe the job.
Why act early in Locheport
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- A sealant colour to suit the surroundings
- One-year guarantee on every job
- Anti-fungal sanitary silicone in wet areas
- Trusted Arbo and Everbuild sealants

What we are called out for in Locheport
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
Around Locheport, as everywhere, window mastic is only as good as the preparation behind it.
Questions to ask before you book
- Who turns up on the day
- What preparation is included
- Whether the sealant suits the joint
- What insurance they hold
Window mastic in Locheport: local notes
Locheport is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Island weather, with its wind and salt spray, is tough on the mastic around window and door frames.
For jobs in and around Locheport, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
