Window Mastic in Forres
Window and door frames in Forres need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
Window mastic in Forres
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on aluminium frames, uPVC windows and window sills, and common reasons people get in touch are draughty joints inside around the window and white mastic on grey or black frames.
Harled walls are common in Scottish towns like Forres, and sealing a frame against rough harling takes a sealant that grips and moves. A thin bead that hasn’t been worked into the surface soon lets water behind it.
All of our work is guaranteed for twelve months.

For landlords and businesses
We also work for property managers and facilities teams in Forres and across Moray. We can quote a run of properties together, and we’re fully insured.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Joints and surfaces we work on
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- Composite doors
- uPVC windows

Common problems we fix in Forres
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Common reasons people contact us include:
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- White mastic on grey or black frames
Rented homes near Forres station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Before booking anyone
- How the colour is chosen
- Which sealant they’ll use, and why
- Is VAT in the price?
- Whether they’re fully insured
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

What else we do in Forres
Windows and doors in Forres
Forres is within about 3 miles of 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Castlehill Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Andersons Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Repaint timber before it’s bare
- Ventilate rooms so frames do not stay wet inside
- Avoid blasting the frames with a pressure washer
- Use gentle cleaners on frames and sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. A visit in Forres needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
