What affects the quote in Oban
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- The size of the job
- Mould in or behind the old joints
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- How many joints, rooms or windows are involved
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.
Sand mastic in Oban, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you’re dealing with cracked mastic round a front door frame and silicone on a period window that looks wrong, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
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.

Common questions in Oban
Is sand mastic in a coastal place like Oban any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Oban station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you offer different sealant colours?
In most cases you can choose. We’ll explain which colours are available.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Signs you need sand mastic in Oban
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Common reasons people contact us include:
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
In the older streets around Old Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- When the joint can take water or movement
- What insurance they hold
- Which colour the sealant will be
- How the surfaces are prepared before sealing
How the job changes by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Looking after it afterwards
Aftercare is simple:
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere like Oban may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Advice
Windows and doors in Oban
Oban is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Schools such as Oban High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Oban station, older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What sealant work can’t fix
We will not take on work that will not last, so these are the limits:
- Sashes that need overhauling
- Broken panes
- Whether work needs listed building consent
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
