When is the sealant fully cured?

Can I paint over the new sealant?

How we handle window mastic in Busby
Around Busby we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We’re often asked to deal with draughty joints inside around the window and a bead that doesn’t match the frame, across window sills, uPVC windows and timber windows & doors.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
What window mastic looks like in Busby
Busby is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. Historic houses like Pollok House (about 4 miles north-west) are a reminder that the area around Busby has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Busby station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as St Margaret Mary's Secondary School, its window and door frames need their mastic kept sound, just like a home’s. Pollok House, about 4 miles north-west, is one of the historic houses in the wider area around Busby.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
- Use gentle cleaners on frames and sealant
- Keep timber frames painted
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Landlords and letting agents in Busby can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
