About our sand mastic in Gourdon
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked, across sash and case windows, timber door frames and brick reveals.
Outdoor sealant needs a dry surface, so window work around Gourdon is planned around the weather. Let us know about access to every frame, including any upstairs.
Each job carries a 12-month guarantee, large or small.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Advice
Common problems we fix in Gourdon
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
These are the problems we are asked about most:
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
Homes close to Old Parish Church And Churchyard include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Is VAT in the price?
- How long to leave it before use
- How much experience the applicator has
- Which colour the sealant will be
What sand mastic looks like in Gourdon
Gourdon is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Gourdon, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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 else we do in Gourdon
Gourdon: your questions answered
Do you cover smaller places like Gourdon?
Yes, Gourdon 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.
Is sand mastic in a coastal place like Gourdon any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How long will you be here?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Gourdon.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Clear gutters so water doesn’t pour onto the windows
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
