DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How we handle sand mastic in Barr
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We are often asked to deal with gaps round a timber door in stone or brick and patchy fillers round a sash window, on sash and case windows, period & listed homes and brick reveals.
Outdoor sealant needs a dry surface, so window work around Barr is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Every job is covered by a 12-month guarantee.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Barr 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.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Advice
How to look after the new joints
Looking after new joints is easy:
- Plan mastic work ahead of painting
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Landlord and commercial work in Barr
Landlords and agents in Barr can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Frames and glazing around Barr
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In the older streets around Old Parish Church And Churchyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
In and around Barr, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
Why act early in Barr
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Barr, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs 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.

- One-year guarantee on every job
