Bower Window Mastic
We cover Bower for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In an older home around Bower, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

About our window mastic in Bower
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on aluminium frames, patio & French doors and composite doors, and the jobs we see most are gaps where the sill meets the wall and a bead that doesn’t match the frame.
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.
Big or small, you get the same 12-month guarantee.

Your questions about window mastic in Bower
Is Bower within the area you cover?
Yes, Bower is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is window mastic in Bower guaranteed?
All our work, in Bower and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. We cover Bower and the rest of Highland.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
How the job changes by surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Landlords, agents and businesses in Bower
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal

Frames and glazing around Bower
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Bower Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes most of a day for a typical house, less for a few frames. Outdoor work around Bower depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Advice
Signs you need window mastic in Bower
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
People usually contact us after spotting one of these:
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
In and around Bower, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
- How long the guarantee is
- Whether all the old sealant comes out first
Looking after it afterwards
After the cure time, these simple habits help:
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Silicone cannot normally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
