Window mastic for homes and businesses in Grange
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on composite doors, uPVC windows and aluminium frames, and common reasons people get in touch are draughts coming in around windows and doors and leaking joints at the ends of sills.
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’ll sort it.

Window mastic in Grange: local notes
Grange 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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Grange, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- How much there is to do
- How much old sealant there is and how hard it is to remove
- 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, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
When you call or email, it’s useful to know:
- Photos by email, if that’s easy
- What’s wrong with the joints now
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
We do not publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, email us at info@mrmastic.co.uk.
When to call us in Grange
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us include:
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
- Water coming in at the bottom corners of a door
For jobs in and around Grange, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- What guarantee comes with the work
- What happens if the job turns out different
- How long to leave it before use
- Whether they seal over old material or remove it
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes most of a day for a typical house, less for a few frames. For a place like Grange, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention if the joints have been sealed before
- Mention any tricky access
- Clear the area around the work

Advice
Common questions in Grange
Will you come out to Grange?
Yes. Grange is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Grange in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Grange is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Is the work guaranteed?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
What we can’t put right
A few problems are outside what sealant work can do:
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Where we work in Grange
- uPVC windows
- Composite doors
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- Window sills
How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Grange, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
