Eco Sash & Case is an Edinburgh joinery firm that makes and fits traditional timber windows and doors, with most of its work concentrated on the sash-and-case windows that older Scottish homes are built around. The company runs its own workshop at Old Dalkeith Road and manufactures the windows there, which is worth stating up front because a lot of firms in this trade subcontract the joinery or simply resell factory units. Making the frames in-house gives Eco Sash & Case more control over profiles and detailing, and it counts most on older properties where an off-the-shelf window looks wrong the moment it goes in.
In-house manufacturing of timber windows
The core of the Eco Sash & Case offering is sash-and-case work in three forms: repair, refurbishment, and full replacement. Repair and refurbishment tend to be what people actually need when a window sticks, rattles, or lets in draughts but the frame itself is sound, and it is sensible that the firm treats those as first-class services instead of nudging everyone toward a costly rip-out. Alongside the sash windows there is casement installation and refurbishment, so both of the common timber window styles are covered. That breadth means a homeowner with a mix of window types across one house can deal with a single contractor.
Repair, refurbishment, replacement services
Glazing options are spelled out in reasonable detail. The site covers double glazing, secondary glazing, and acoustic or safety glass, which points to a firm thinking about noise and energy, beyond simply replacing glass like for like. Secondary glazing in particular is the pragmatic choice for a listed or conservation property where the original window cannot be altered much, so its presence here fits the specialism the firm claims. Draught proofing, window painting, and mastic repairs round out the smaller jobs Eco Sash & Case takes on, and there is a shutters line too.
Glazing options for listed properties
Eco Sash & Case handles doors across three materials: wooden, composite, and uPVC. And for cases where planning rules allow it, the firm also fits modern uPVC and aluminium window alternatives. That is a fair way to present it, since the timber-versus-plastic question is usually settled by what the local authority permits rather than by preference alone. A firm that leads with heritage timber but is honest that plastic is sometimes the sanctioned or cheaper route comes across as practical instead of dogmatic.
What materials does Eco Sash & Case work with?
The heritage angle is the part that gives Eco Sash & Case a clear identity. The firm specialises in listed properties and buildings recognised by Heritage Scotland, and the work is conservation-sensitive: the wrong material or the wrong glazing bar can breach planning consent. Edinburgh has a huge stock of tenements and Georgian and Victorian houses under exactly those controls, so a contractor that understands the constraints is genuinely useful there. This is not generic window-fitting; it is the kind of work where knowing the rules is half the job.
Heritage specialism and conservation rules
On who it serves, Eco Sash & Case names homeowners, landlords, and trade professionals. That trade-facing element is a point in its favour, because other joiners and builders bringing work to a supplier usually means the finished product satisfies a professional eye. Landlords are a logical fit too, given how much of Edinburgh's period housing is rented and subject to repair obligations.
The Eco Sash & Case website itself is more built-out than the usual trade site. Beyond the service pages there is an About section, client testimonials, a news and advice area, case studies, current vacancies, finance options, and an FAQ. Case studies are the most useful of these for a prospective customer, since photographs of completed jobs on real properties say more than any description. Finance options are a practical inclusion given that a full window replacement across a house is a significant outlay. The vacancies page adds to that impression: a firm actively hiring joiners has steady work, not a solo operation stretched across every job.
Contact details for Eco Sash & Case are easy to find and complete. There is a phone number, a workshop address on Old Dalkeith Road, and stated office hours running Monday to Thursday until half four and a shorter Friday, plus a booking section for arranging quotes. A physical workshop that a customer could in principle visit, tied to a specific address and set hours, is reassuring for a trade where fly-by-night operators are a real hazard. Nothing here reads as evasive.
Checking independent reviews and ratings
External reviews look broadly strong, with one wrinkle worth noting. The main UK Trustpilot listing shows a five-star rating across 43 reviews, which is a solid volume for a regional joinery firm. There is a separate Australian Trustpilot mirror sitting at four stars from 36 reviews, which most likely reflects a listing mix-up or a differently attributed profile rather than a genuine second market, and anyone checking should weigh the UK page as the relevant one. Bark.com rates Eco Sash & Case five stars and ProvenExpert hosts a reviews profile as well, while the Facebook page carries customer posts referencing five-star feedback. The firm also keeps its own reviews page, which counts for less than the independent platforms but lines up with them.
The reservations are modest ones. The Bark listing files Eco Sash & Case under patio contracting, which sits oddly against a joinery specialist and suggests its category tags are not perfectly tidy across every platform. Testimonials collected on a company's own site should always be read with the usual caution, though here they line up with the external ratings instead of contradicting them. And the split Trustpilot picture, while probably innocent, is something a careful buyer would want to confirm before booking anything.
Taken together, Eco Sash & Case looks like a credible, established option for period-property window work in and around Edinburgh, with in-house manufacturing, a defensible heritage specialism, and consistent independent ratings behind it. The verdict is positive but not unqualified: get a written quote, ask to see case studies close to the relevant property type, and confirm which reviews profile actually pertains to the Edinburgh operation. For sash-and-case repairs on an older Scottish home, this is a sound name for the shortlist, and the published evidence gives a homeowner plenty to check against.
