Kirkpatrick Durham homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Schools such as Kilquhanity School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Window mastic for homes and businesses in Kirkpatrick Durham
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. We work on patio & French doors, uPVC windows and timber windows & doors, and common reasons people get in touch are draughty joints inside around the window and black, perished sealant on frames.
Mastic can only go onto a dry joint, so outside work in Kirkpatrick Durham depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Our work is backed for twelve months.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Kirkpatrick Durham depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- On commercial sites, let us know about site rules

Signs you need window mastic in Kirkpatrick Durham
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Keep an eye out for these signs:
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
Around Kirkpatrick Durham, as everywhere, window mastic is only as good as the preparation behind it.
Questions to ask before you book
- Which colour the sealant will be
- Is VAT in the price?
- What product goes in the joint
- Who turns up on the day
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
