Hirst homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Hirst, as everywhere, window mastic is only as good as the preparation behind it.

Window mastic for homes and businesses in Hirst
Homes in Hirst have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include cracked or shrunken mastic around the frame and rushed sealant from a window installation, on uPVC windows, patio & French doors and composite doors.
Outdoor sealant needs a dry surface, so window work around Hirst is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What the job involves on each surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We’ll tell you if that’s what we find.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
When something else is needed
Before booking, it’s worth knowing the limits too:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Composite doors
- Window sills
- Aluminium frames
- Timber windows & doors
- uPVC windows
- Patio & French doors
Why deal with it now?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a place like Hirst, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

FAQs for Hirst
Can you help a landlord with a rental near Shotts station?
Yes. We work for letting agents and landlords as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Hirst?
Yes. Hirst is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Does the work come with a guarantee?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
What information do you need?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Other services in Hirst
Do you need window mastic in Hirst?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Signs it’s time to call us include:
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
If you let a flat or house near Shotts station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door. Outside jobs in Hirst need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t 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.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Clear the area around the work
