Window Mastic in Dalmore
We cover Dalmore for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- A bead that doesn’t match the frame
- Draughts coming in around windows and doors
- Black, perished sealant on frames
What we do, step by step
At the end, we look at the finished work together. The work normally takes a morning for a couple of windows and a door, depending on how much there is to do. Outdoor work around Dalmore depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

About our window mastic in Dalmore
The new joint doesn’t 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 black, perished sealant on frames and gaps between the frame and the inside reveal, we can help.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job comes with a one-year guarantee, wherever you are in Highland.

Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
When something else is needed
We won’t take on work that will not last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Windows and doors in Dalmore
Dalmore is close to 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Alness station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Rosskeen Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the quote in Dalmore
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- Access and height
- The product the joint needs
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
What we need to know
When you call or email, these details help:
- Where the property is
- How many joints, rooms or windows are involved
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
Signs you need window mastic in Dalmore
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
The problems people normally mention when they call are:
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
If you look after a building such as Alness Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Dalmore: your questions answered
Do you cover smaller places like Dalmore?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Alness station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee, and we are fully insured.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Landlord and commercial work in Dalmore
Landlords and letting agents in Dalmore can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
We also work for property managers and facilities teams in Dalmore and across Highland. We can quote a run of properties together, and we’re fully insured.
