What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a couple of windows and a door. Around Glenmavis, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Move anything stored near the joints

Related advice
Window mastic in Glenmavis
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We are often asked to deal with sealant in the wrong colour for the frame and draughty joints inside around the window, on patio & French doors, aluminium frames and composite doors.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Do I need to be at home?

When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
How do I get a quote for window mastic in Glenmavis?

What window mastic looks like in Glenmavis
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Coatdyke station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Airdrie Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

Quotes for window mastic in Glenmavis
Jobs vary more than people expect. What affects the quote:
- How much there is to do
- Mould in or behind the old joints
- Access and height
- Which sealant suits the joint
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- The address or postcode of the job
- Any previous sealing or DIY work
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, drop us a line at info@mrmastic.co.uk.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Landlords, agents and businesses in Glenmavis
For anyone letting property in or around Glenmavis, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Why act early in Glenmavis
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What else we do in Glenmavis
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Draughts through the window seals rather than the frame
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

Surface by surface
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
