Window mastic in Brechin, done properly
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have old mastic that has gone black or come away and sealant in the wrong colour for the frame, we can put it right, whatever the surface.
In and around a place like Brechin, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Each job carries a 12-month guarantee, whatever its size.

What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots aren’t blocked
- Keep paint off silicone joints
Most silicone sealants will not take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a morning for a couple of windows and a door. Somewhere like Brechin may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
How to get a quote

Common problems we fix in Brechin
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
People normally contact us when they notice something like this:
- Cracked internal joints between frame and plaster
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
In and around Brechin, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Who turns up on the day
- Whether you can choose the colour
- How the joint is cleaned and prepared
- What guarantee comes with the work
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Common questions in Brechin
Is there a guarantee on window mastic in Brechin?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Brechin?
Yes. Brechin 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.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Angus.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Windows and doors in Brechin
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Brechin High School, its window and door frames need their mastic kept sound, just like a home’s.
