The process
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 a morning for a couple of windows and a door in most cases. Outdoor work around Monifieth depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Advice
Window mastic for homes and businesses in Monifieth
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on timber windows & doors, uPVC windows and aluminium frames, and the jobs we see most are old mastic that has gone black or come away and cold air getting in at the frame edge.
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.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Windows and doors in Monifieth
Monifieth 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, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Monifieth station, renewing tired window mastic between tenants heads off draught and damp complaints.

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- How easy the joints are to reach
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Access, such as stairs, a lift or height
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
What we are called out for in Monifieth
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Managing a site like Grange Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Landlords, agents and businesses in Monifieth
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Does the coastal weather in Monifieth affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

How long does it take to reseal the windows on a house?
The work takes most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
