Mastic around window and door frames, sills and patio doors for California, backed by a one-year guarantee. Call for a quick quote.
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- White mastic on grey or black frames
How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames in most cases. Outdoor work around California depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- On commercial sites, let us know about site rules

Advice
How we handle window mastic in California
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. Typical jobs include gaps where the sill meets the wall and cold air getting in at the frame edge, across patio & French doors, composite doors and aluminium frames.
Outdoor sealant needs a dry surface, so window work around California is planned around the weather. Let us know about access to every frame, including any upstairs.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

California questions
Do you work for landlords with property near Polmont station?
Yes. We work for landlords and agents as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is California within the area you cover?
Yes. California 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.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
How do I get a quote for window mastic in California?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
- A sash or casement that won’t close properly
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal

Landlords, agents and businesses in California
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
What window mastic looks like in California
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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you let a flat or house near Polmont station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Do you need window mastic in California?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The problems people usually mention when they call include:
- Mastic that’s falling out in pieces
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
Schools such as Graeme High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- What guarantee comes with the work
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
DIY sealant or a professional job?
If you are 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
