Window mastic in Ullapool
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on window sills, patio & French doors and aluminium frames, and people most often call us about black, perished sealant on frames and water coming in at the bottom corners of a door.
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.
Every job comes with a 12-month guarantee, wherever you are in Highland.

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
Landlords, agents and businesses in Ullapool
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

What we’re called out for in Ullapool
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
These are the problems we are asked about most:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
- Cracked internal joints between frame and plaster
Homes close to Ullapool old parish church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before you book anyone
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
- The length of the guarantee
- Whether they’re fully insured
Aftercare tips
Looking after new joints is easy:
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Use gentle cleaners on frames and sealant
- Don’t use solvent cleaners on the joint
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
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. Catching it early keeps the fix to a reseal.
The process
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before we start. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere like Ullapool may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Advice
Ullapool questions
Is Ullapool in your area for window mastic?
Yes, Ullapool is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Does living near the coast affect window mastic in Ullapool?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
What sealant work can’t fix
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

- Mould in or behind the old joints
- The type of sealant required

Windows and doors in Ullapool
Ullapool is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Ullapool School, the mastic around its windows and doors needs looking after like any other building’s.
