Window mastic in Shewalton
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We work on uPVC windows, timber windows & doors and aluminium frames, and common reasons people get in touch are damp patches on the reveal after heavy rain and old mastic that has gone black or come away.
Outdoor sealant needs a dry surface, so window work around Shewalton is planned around the weather. Let us know about access to every frame, including any upstairs.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that is a job for a joiner.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Around Shewalton, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

Shewalton homes and the weather
Shewalton is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Girgenti House (about 4.6 miles north) are a reminder that the area around Shewalton has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Greenwood Academy, larger buildings have plenty of frames, and the mastic around each one ages. Girgenti House, about 4.6 miles north, is one of the historic houses in the wider area around Shewalton.

Why it’s worth doing now in Shewalton
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In a place like Shewalton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
