Specialist window mastic for Collieston: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Black, perished sealant on frames
- Draughty joints inside around the window
- Gaps left after new windows were fitted
How we handle window mastic in Collieston
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, aluminium frames and window sills, and common reasons people get in touch are gaps between the frame and the inside reveal and gaps where the sill meets the wall.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Your job is guaranteed for a year, as with all our work.

When to call us in Collieston
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That is what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- White mastic on grey or black frames
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
- Mastic that has split away from the wall
Around Collieston, as everywhere, window mastic is only as good as the preparation behind it.
Questions to ask before booking
- Whether the sealant suits the joint
- What preparation is included
- How long the guarantee is
- How the colour is chosen
What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
What affects the quote in Collieston
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Which sealant suits the joint
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- How many joints, rooms or windows are involved
- How we’d reach the joints
We quote each job on its own. Just drop us a line at info@mrmastic.co.uk with the details and send photos if you have them.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Collieston 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.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
- Every joint is tooled smooth and checked before we leave.

Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator
- One-year guarantee on every job
- Arbo and Everbuild products

Frames and glazing around Collieston
Collieston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Parish Church of Slains include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
