DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
About our window mastic in Hillend
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you’re dealing with draughts coming in around windows and doors and cracked internal joints between frame and plaster, we can help, whatever the surface.
In and around a place like Hillend, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
You get a 12-month guarantee, the same in Hillend as everywhere else we work.

Window mastic in Hillend: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Whether the job is in Hillend itself or nearby, the right material for each joint matters as much as a neat finish.
Hillend is about 2 miles south-east of Forfar, in Angus. Homes, rented property, offices and hotels in Hillend is covered for window mastic. Every job comes with our 12-month guarantee. 40 places in Angus are on our list. There’s also a page for Dundee, roughly 12 miles from Hillend.

Why act early in Hillend
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. 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.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

Do you need window mastic in Hillend?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
People generally contact us after spotting one of these:
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Cracked sealant at the sill ends
In and around Hillend, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

FAQs for Hillend
Is Hillend within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Hillend for window mastic?
Yes. Our work covers the whole of Scotland, and Hillend is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
How long will my window job take?
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.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Around Hillend, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First we look at every frame and agree the list.
- 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.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
