How the job changes by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as that is a job for a joiner.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
How we handle window mastic in Greenock West
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, aluminium frames and uPVC windows, and the jobs we see most are damp patches on the reveal after heavy rain and untidy mastic left by window fitters.
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.
You are covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Patio & French doors

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
- Don’t paint over the silicone
- Wipe condensation off the frames
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What affects the cost of window mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- How many rooms, windows or areas are involved
- Access and height
- The old material and how stubborn it is
- When we can work, for business premises
Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
Asking for a quote
When you call or email, these details help:
- The rough size of the job
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, email us at info@mrmastic.co.uk.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Frames and glazing around Greenock West
Greenock West is close to 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Rented homes near Greenock West station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Historic houses such as Ardgowan House, about 4.6 miles south-west, show how far back building around Greenock West goes, and older homes nearby need a sealant that suits their walls. If you look after a building such as Greenock Academy, its window and door frames need their mastic kept sound, just like a home’s.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Outside jobs in Greenock West need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
