How we handle sand mastic in Summerhill
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on period & listed homes, tenement windows and timber door frames, and people most often call us about draughts and rain around sash boxes and silicone on a period window that looks wrong.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Summerhill, and in a tenement the outside of the building may be a shared repair.
Big or small, it’s backed by our one-year guarantee in Summerhill and across Aberdeen.

Why act early in Summerhill
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Scottish rain finds any gap around a frame or wall joint, and in Summerhill, damp can spread through stone and plaster before anyone sees it.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Make sure water runs off the sill
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Parking in city streets around Summerhill 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.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- Mention any parking rules near the property

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
