FAQs for Dryburgh
Who arranges sealant work on the shared parts of a tenement in Dryburgh?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Does living near the coast affect window mastic in Dryburgh?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Window mastic in Dryburgh
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on aluminium frames, uPVC windows and timber windows & doors, and common reasons people get in touch are mastic that has split away from the wall and whistling draughts around closed windows.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Dryburgh, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Big or small, it’s backed by our one-year guarantee in Dryburgh and across Dundee.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Parking in city streets around Dryburgh can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any parking rules near the property
- Clear items away from the joints we are working on
- Mention any tricky access

Honest limits
It helps to know what we can’t do:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- Damp problems in the wall away from the window
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Patio & French doors
- Window sills
- Timber windows & doors
- Aluminium frames
- Composite doors
- uPVC windows
Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Common problems we fix in Dryburgh
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
The most common problems we see are:
- Mastic that is falling out in pieces
- Sealant in the wrong colour for the frame
- Damp patches on the reveal after heavy rain
- Cracked internal joints between frame and plaster
For an older house near a landmark such as Lochee Baptist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid blasting the frames with a pressure washer
- Look round the frames every year or so
- Make sure the drainage slots are not blocked
- Paint up to the joint, not over it
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Frames and glazing around Dryburgh
Dryburgh is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Menzieshill High School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Invergowrie station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
