- Rushed sealant from a window installation
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. Parking in city streets around Newcraighall can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Advice
Window mastic in Newcraighall
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. Either or both can be done. We work on patio & French doors, window sills and aluminium frames, and common reasons people get in touch are a bead that doesn’t match the frame and cracked sealant at the sill ends.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you’re in a tenement flat or a house in Newcraighall, the joint between frame and wall is what keeps the weather out.
Every job comes with a one-year guarantee, wherever you are in Edinburgh.

What else we do in Newcraighall
How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Landlord and commercial work in Newcraighall
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Why deal with it now?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a tenement flat in Newcraighall, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why us?
- 20+ years of sealant experience
- Domestic, commercial and hotel work
- A 12-month guarantee on all work
- Quality sealants from Arbo and Everbuild

Newcraighall questions
How is work on the outside of a tenement in Newcraighall normally arranged?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Do you work for landlords with property near Newcraighall station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you work on first-floor windows?
Generally, yes. We plan safe access before the job, so mention the height and anything in the way.
How many windows can you do in a day?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Window mastic in Newcraighall: local notes
Newcraighall is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Melville Castle (about 3.1 miles south) are a reminder that the area around Newcraighall has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Portobello High School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Newcraighall station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

Signs you need window mastic in Newcraighall
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Signs it’s time to call us include:
- Cracked or shrunken mastic around the frame
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Whistling draughts around closed windows
Melville Castle, about 3.1 miles south, is one of the historic houses in the wider area around Newcraighall.
What to look for in a quote
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- Whether the sealant suits the joint
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Air rooms to keep condensation down around windows
- Check the mastic once a year
- Wash the frames with mild soapy water
- Make sure the drainage slots are not blocked
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
