What we are called out for in Portree
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
Common reasons people contact us are:
- Cracked mastic round a front door frame
- Patchy fillers round a sash window
- Modern sealant on a period surround
- Mastic dropping out of the joint
Managing a site like Portree High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How we handle sand mastic in Portree
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you have mastic worn away on windows facing the weather and gaps between timber frames and stone or brick, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
All our work comes with a one-year guarantee.

Different surfaces, different methods
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
For landlords and businesses
For anyone letting property in or around Portree, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a single window, longer for several from start to finish. Outside jobs in Portree need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
- Plan mastic work ahead of painting
- Don’t paint over the new mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

Portree homes and the weather
Portree is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
In the older streets around St Columba's Episcopal Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the cost of sand mastic
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- Any working-time requirements on site
- Mould in or behind the old joints
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
