How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for a single window, longer for several, depending on how much there is to do. For a place like Trumpethill, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.

Related advice
Sand mastic in Trumpethill, done properly
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Common call-outs are for gaps between timber frames and stone or brick and window mastic to renew ahead of painting, on timber door frames, brick reveals and period & listed homes.
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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Trumpethill homes and the weather
Trumpethill 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. Historic houses like Ardgowan House (about 2.4 miles south) are a reminder that the area around Trumpethill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Gourock High School, larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Ardgowan House, about 2.4 miles south, show how far back building around Trumpethill goes.

Do you work for landlords with property near Gourock station?
Yes, we work for letting agents and landlords. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Does the coastal weather in Trumpethill affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Can you quote for more than one area?
Yes. Just list everything you need.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later, and we will tell you what to expect.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
- Check the mastic when you check the paintwork
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
