Window & door mastic in Whitehouse, Argyll and Bute
Professional window mastic in and around Whitehouse, with every bit of old sealant taken out first and a one-year guarantee.
- Cracked or shrunken mastic around the frame
- A bead that doesn’t match the frame
- Cracked internal joints between frame and plaster
Window mastic in Whitehouse
There are two joints on most windows. 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 uPVC windows, patio & French doors and window sills, and people most often call us about rain getting in at the frame or under the sill and rushed sealant from a window installation.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Work for landlords, hotels and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants 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. We can quote a run of properties together.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Whitehouse depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

When to call us in Whitehouse
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
The problems people usually mention when they call are:
- White mastic on grey or black frames
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
Around Whitehouse, as everywhere, window mastic is only as good as the preparation behind it.
Before booking anyone
- The length of the guarantee
- How the joint is cleaned and prepared
- How hidden problems are handled
- Whether all the old sealant comes out first
Keeping the joints in good condition
Looking after new joints is easy:
- Repaint timber before it’s bare
- Do not use solvent cleaners on the joint
- Ventilate rooms so frames do not stay wet inside
- Paint up to the joint, not over it
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
Common questions in Whitehouse
Can you do window mastic in Whitehouse?
Yes, Whitehouse is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Is window mastic in a coastal place like Whitehouse any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
Do you have insurance?
Yes, we’re fully insured.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How do I get a quote for window mastic in Whitehouse?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What we can’t put right
In fairness, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal
- Window sills
- Patio & French doors
- Composite doors
- Timber windows & doors
- uPVC windows
- Aluminium frames
Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Windows and doors in Whitehouse
Whitehouse is within about 1 mile of 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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Whitehouse itself or nearby, the right material for each joint matters as much as a neat finish.
Whitehouse (Gaelic: Glac a' Mhuilinn) is about 29 miles west of Saltcoats, in Argyll and Bute.

Whitehouse is one of 118 places in Argyll and Bute we cover. We also work in Glasgow, about 47 miles from Whitehouse.

Landmarks near Whitehouse
A little further out are Loup House (4 miles south-west). Not far away are Lochan Liath and Cruach na Caol-bheinn.
Why deal with it now?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a place like Whitehouse, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
