Sand Mastic in Lionel
Sand mastic across Lionel and nearby, with old sealant always removed completely and a 12-month guarantee.
- Tired mastic found when preparing windows for paint
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a single window, longer for several. Outdoor work around Lionel depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

About our sand mastic in Lionel
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. If you have gaps round a timber door in stone or brick and modern sealant on a period surround, we can put it right.
Mastic can only go onto a dry joint, so outside work in Lionel depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Each job carries a 12-month guarantee, whatever its size.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Lionel questions
Do you cover Lionel for sand mastic?
Yes, Lionel is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Does living near the coast affect sand mastic in Lionel?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Landlords, agents and businesses in Lionel
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What else we do in Lionel
Frames and glazing around Lionel
Lionel is close to 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. On the islands, wind and salt spray are hard on outside sealant.
If you look after a building such as Lionel School, its window and door frames need their mastic kept sound, just like a home’s. Around Lionel, as everywhere, sand mastic is only as good as the preparation behind it.
Lionel is about 20 miles north of Stornoway, in Na h-Eileanan Siar. Jobs in Lionel get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our area takes in 87 places across Na h-Eileanan Siar, large and small.
Postcode districts we cover here for sand mastic: HS2. We also cover Lìonal (1 mile north-west), Coig Peighinnean (1 mile north), Nis (1 mile south-west), Ness (1 mile south) and Sgiogarstaigh (1 mile south-east).

Other landmarks nearby include Ness Heritage Centre (0.6 miles south-west).
Why deal with it now?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. In a place like Lionel, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
What affects the cost of sand mastic
Your quote is based on your job. We look at:
- Whether the work is at height
- The size of the job
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
