Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep drainage slots and sill grooves clear
- Don’t use solvent cleaners on the joint
- Look round the frames every year or so
- Don’t paint over the silicone
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Window mastic in Dalmally
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Typical jobs include whistling draughts around closed windows and damp patches on the reveal after heavy rain, across window sills, aluminium frames and patio & French doors.
Mastic can only go onto a dry joint, so outside work in Dalmally depends on the weather. Tell us about access to all the windows and doors, upstairs included.

What window mastic looks like in Dalmally
Sash and case windows are common in older Scottish homes, 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.
Letting a property close to Dalmally station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Glenorchy Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Common questions in Dalmally
Is Dalmally within the area you cover?
Yes, Dalmally is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Dalmally station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long does it take to reseal the windows on a house?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
How do I get a quote for window mastic in Dalmally?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Do you guarantee window mastic?
Yes. Our 12-month guarantee covers every job.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How the job changes by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes most of a day for a typical house, less for a few frames. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
