Bourtreehill Window Mastic
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Bourtreehill. Fully insured, ARBOMaster approved and guaranteed for a year.
- Rain getting in at the frame or under the sill
- A bead that doesn’t match the frame
- Draughty joints inside around the window
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Wipe condensation off the frames
- Keep paint and stain on wooden frames in good order
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
About our window mastic in Bourtreehill
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, patio & French doors and composite doors, and the jobs we see most are draughty joints inside around the window and mastic that’s falling out in pieces.
Outdoor sealant needs a dry surface, so window work around Bourtreehill is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, in Bourtreehill and everywhere else we cover.

Window mastic in Bourtreehill: local notes
Bourtreehill is within about 3 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. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Rented homes near Irvine station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Girgenti House, about 3.1 miles north, is one of the historic houses in the wider area around Bourtreehill.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It usually takes most of a day for a typical house, less for a few frames. Outside jobs in Bourtreehill need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare

What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.

Common problems we fix in Bourtreehill
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Mastic that is falling out in pieces
- Damp patches on the reveal after heavy rain
For site and facilities teams at buildings such as Greenwood Academy, its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Bourtreehill
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In an older home around Bourtreehill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.
