Can you match the sealant to my frames?

How long will my window job take?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Can I paint over the new sealant?

Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- Working hours on commercial sites
- The product the joint needs
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What we need to know
To make quoting easier, please include:
- The type of property
- The address or postcode of the job
- Any access issues, like height or stairs
- What’s wrong with the joints now
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work generally takes a morning for a couple of windows and a door. Outdoor work around Mid Calder 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Mention any tricky access
- Move anything stored near the joints
- Let us know about parking restrictions

Mid Calder homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. With historic houses such as Howden House (about 1.4 miles west) nearby, there’s older building stock in the area around Mid Calder as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Livingston South station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Mid Calder Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Inveralmond Community High School? Then the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
After the cure time, these simple habits help:
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
- Paint up to the joint, not over it
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
- A sash or casement that won’t close properly
