Window Mastic in Dullatur
Problem with your window and door frames in Dullatur? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Water coming in at the bottom corners of a door
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
How we handle window mastic in Dullatur
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have cracked sealant at the sill ends and cracked internal joints between frame and plaster, we can help, on patio & French doors, window sills and uPVC windows alike.
Outdoor sealant needs a dry surface, so window work around Dullatur is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Every job comes with our one-year guarantee, wherever you are in North Lanarkshire.

Windows and doors in Dullatur
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. Dullatur is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
For site and facilities teams at buildings such as Our Lady's High, its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Dullatur
The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Dullatur, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

What affects the quote in Dullatur
We don’t publish a price list, because no two jobs are the same. What we look at:
- Access and height
- The old material and how stubborn it is
- The size of the job
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
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
- The problem you’ve noticed
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Dullatur 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.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

When it is not the sealant
Before you book, it’s worth knowing the limits:
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Aluminium frames
- Timber windows & doors
- Window sills
- Composite doors
- Patio & French doors
- uPVC windows
Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
What we are called out for in Dullatur
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
People generally contact us when they notice one of these:
- Cracked sealant at the sill ends
- A bead that does not match the frame
- Draughts coming in around windows and doors
- Gaps left after new windows were fitted
Rented homes near Croy station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- Whether they’re fully insured
- How long the guarantee is
- What the cure time is
- Which colour the sealant will be

Do you cover Dullatur for window mastic?
Yes. We work across all of Scotland, and Dullatur is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Is Dullatur within the area you cover?
Yes, Dullatur is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is the new sealant paintable?
Not normally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
