Birsemore questions
Do you cover smaller places like Birsemore?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in Birsemore guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Window mastic for homes and businesses in Birsemore
Homes in Birsemore have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on aluminium frames, timber windows & doors and uPVC windows, and the jobs we see most are mastic that has split away from the wall and leaking joints at the ends of sills.
Outdoor sealant needs a dry surface, so window work around Birsemore is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job.

Birsemore homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you live in an older home near St Machar's Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Aboyne Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a place like Birsemore, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house, and the area is left clean. Outdoor work around Birsemore 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 look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- Clear the area around the work

Advice
What the job involves on each surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.

What to tell us for a quote
You don’t need to know the technical terms. Just tell us:

- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
