We’re rated 5.0 from 62 reviews under East Lothian Trading Standards Trusted Trader, and the work behind that is mostly what you can’t see once the window’s in.
Key Takeaways From This Article
- The reveal, lintel and cill get checked before anything's ordered, because older Tranent openings have moved.
- We do our own making good, so the internal facings and the plaster line are finished by the people who fitted the window.
- Sash windows get repaired where they're sound, with cords, pulleys, weights and spliced cill sections.
- The gap between frame and masonry is insulated and sealed both sides, which is where the draughts actually come from.

Window Installation and Replacement
We’re rated 5.0 from 62 reviews under East Lothian Trading Standards Trusted Trader, and most of that comes from work you can’t see once we’ve gone.
What we check first
The reveal, the lintel and the cill. If the opening’s moved, and in older Tranent stone it usually has, the new frame gets packed and shimmed to sit true rather than forced to fit. Force it and you’ll see the reveal taper from across the room.
Making good
We don’t leave the making good to somebody else. Internal facings, sills and the plaster line get finished by us, because that’s the bit you look at every day. A neat frame with a torn plaster line round it is a job half done.

Doors, Conservatories and Related Glazing for Tranent Homes
Glazed doors and window units in the same elevation need to match, and on a house that’s had work done in stages they usually don’t.
Matching what’s there
We take the sightlines, the glazing bar width and the cill projection off the existing frames before anything’s ordered. That way the new unit doesn’t announce itself. On an elevation that’s been done in stages you’ll usually see three different sightlines already, and we won’t add a fourth.
Joinery around the opening
Facings, linings and window boards are made to the opening, the same way we’d build built wardrobes in Tranent. It’s all the same trade, and it means nobody’s waiting on another firm to finish the inside once the glass is in.

Sash Window Repair and Restoration in Tranent
Round the High Street and Church Street there’s older stock where the sashes are worth keeping. Replacing them isn’t always the right answer and we’ll say so.
What can be saved
Cords, pulleys and weights are replaceable. Rotten cill sections can be spliced. A box frame that’s sound doesn’t need to come out for the sake of it.
Draught proofing and performance
Brush seals in the staff and parting beads make more difference than people expect. We do the same on window installation service in Elphinstone jobs where the stock’s a similar age. Repair first, replace where it’s past it. We’ll tell you which of your sashes fall on each side of that line.

Installation Only and Trade Subcontracting
Some people have already bought their windows and just need them in properly. That’s fine and it’s a common call.
Fitting supplied units
We’ll fit units you’ve supplied, but we’ll survey the openings first and tell you if the sizes are wrong before anything gets ordered or delivered.
Working for other trades
We take fitting work for builders and joiners on the same terms as we’d run a window installation service in Macmerry. Same standard either way, and the survey happens before delivery so a wrong size is somebody’s problem while it can still be changed.

Casement, Flush and Heritage Window Options
The window style has to suit the elevation, not the brochure. A flush casement sits right on older stone. A stormproof casement doesn’t always.
Choosing by the building
We’ll walk round the outside with you and tell you what the house is asking for. Do you have to match the neighbours? No, but on a terrace where the rhythm of the openings is the thing you notice, it’s worth thinking about.
Timber and finish
Timber frames get factory finished before they arrive. Ironmongery is chosen for the weight of the sash rather than the look of the catalogue.

Double Glazing and Energy Efficiency
Sealed units do the heat, but the draughts come round the frame rather than through the glass.
Sealing the perimeter
The gap between frame and masonry gets insulated and sealed both sides. Skip that and the most expensive unit you can buy still feels cold.
Slim profile in older openings
Where a heritage sash is being kept, slim profile units can go into refurbished sashes. It’s not right for every window and we’ll tell you when it isn’t.

Window Fitters in Tranent FAQs
Do I need planning permission to replace windows in Tranent?
Usually not for a like for like replacement, but the historic core round the High Street, Church Street and the Old Parish Church is a different matter and it's worth checking. We'll tell you what your address looks like before you commit.
Can my sash windows be repaired instead of replaced?
Often, yes. Cords, pulleys and weights are replaceable and rotten cill sections can be spliced, so a sound box frame doesn't need to come out. We'll tell you honestly which of yours are worth saving.
Will you fit windows I've bought myself?
Yes. We'll survey the openings first though, and if the sizes are wrong you'll hear it from us before anything's delivered rather than on fitting day.
What about the mess and the making good?
We do our own making good, so the internal facings, the window boards and the plaster line are finished by the same people who fitted the frame. Nothing gets left for another trade.
Can you match the windows on the rest of the street?
We take the sightlines, the glazing bar width and the cill projection off what's already there before anything's ordered. On a terrace where the rhythm of the openings is what you notice, that matters.
