  • Combines modern materials and traditional joinery methods
  • Dedicated to matching the character of the vicinity
  • Manufactures with Accoya timber and uses Fineo glazing system


  • Clients have reported a lack of communication
  • Warranties are not honoured in some cases

If you’re looking to renovate, upgrade, or replace your traditional tinder sash and case windows, you’re in luck. This is the specialty of Edinburgh Sash and Case, a company that services Edinburgh, Lothian, and surrounding areas.

They combine modern materials and traditional joinery methods, and hand-finish all of their windows to keep a balance between quality and aesthetics. Edinburgh Sash and Case does this through in-house workshops and training fitting teams accordingly.

For instance, they manufacture using Accoya timber, which prevents rot for up to 50 years, and use the new Fineo glazing system for increased thermal retention and performance.

Since a significant portion of Edinburgh has been designated as World Heritage, we commend the company’s dedication to matching the overall character of the surroundings while still ensuring the longevity of their work.

Unfortunately, clients have reported that they have experienced a lack of communication; this includes unanswered emails, phone calls, and texts. Warranties have also not been honoured properly in some cases.

Edinburgh Sash and Case is well-recognised in the area with a bigger staff, so we think that clients should be treated better moving forward. Still, the company truly focuses on window replacement, so it remains to be a top option for sash and case issues.

  • Broad range of products and services
  • Carries different window types
  • Rates are on the more affordable side


  • Company has been dealing with staffing issues
  • Not suitable for bigger replacement projects
  • Inconsistencies in professionalism and quality

GR Window & Door Specialists LTD is another locally-established business in Edinburgh. They can refurbish and replace timber sash and case windows, and offer a range of installation services such as UPVC windows, and many kinds of doors.

GR Window & Door Specialists LTD is employed by several letting agencies, housing associations, and other window companies thanks to their many services and window products.

They manufacture casement windows, tilt & turn, fully reversible, and vertical sliders, in addition to traditional sash & case windows. For the latter kind, they also offer full restoration, draught-proofing, minor resin repairs, and missing putty & panes services.

GR Window & Door Specialists LTD can also undertake both single and double-glazing work. With all the services they offer, we were glad to find that their rates are more on the affordable side as well.

However, the company has been struggling with staffing issues, so it will likely refuse to take on bigger projects. The staffing issues have led to a few inconsistencies when it comes to professionalism and quality, as some projects end up being a bit rushed.

If you’re on a budget and are looking to get a few windows repaired or replaced, then GR Window & Door Specialists LTD might be the best for you, because of their range of products and their affordable prices.

  • Over 30 years of experience in the industry
  • Extensive range of products and services
  • 24-hour emergency glazing services


  • Lack of communication with customers
  • Prices are a bit more expensive

Edinburgh Glass & Glazing has been supplying the city with high-quality windows for over 30 years. They are popular for both commercial and domestic installations and their vast range of services.

These encompass double-glazing window repairs, emergency glazing, UPVC windows, and more. They also deal with doors, glass-cutting, and comprehensive bathroom services including mirrors and splashbacks – ideal for homes under renovation.

Edinburgh Glass & Glazing specialises in domestic and commercial glazing, and their emergency double glazing repair service is available for 24-hours a day around East and West Lothian, Midlothian, and the surrounding areas.

They also offer a unique solar film glazing service, which minimises the amount of sunlight and UV rays that come shining through your property. Edinburgh Glass & Glazing continues to find ways to innovate through products such as this.

Edinburgh Glass & Glazing has consistently received good reviews online, with few complaints about the company aside from the occasional lack of communication, and that their rates are more on the expensive side.

We think that although clients will have to splurge a bit, the quality and expertise they pay for seem to be well worth the price. After all, Edinburgh Glass & Glazing is a trusted company with over 30 years of industry experience.

  • Family firm working in the industry for over 25 years
  • Provides stylish, energy-efficient, high-security windows
  • Casement, vertical slide, and reversible window styles


  • Warranties aren’t honoured in some cases 
  • Some customers have reported poor after-sales service

Ideal Windows and Conservatories is a company that works primarily with windows, glass constructs, and home extensions. They’re a family firm that has been practising in Edinburgh for over 25 years, earning a lot of return clients around the area.

They have an array of stylish, energy-efficient, and high-security windows that are perfect for customers who want to add a bit of modernity to their houses. Customers can choose from casement, vertical slide, and reversible styles.

All their products are double-glazed, and every installation is bespoke and customised to each client’s specific needs. Additionally, they specialise in creating conservatories, orangeries, sunrooms, and other living spaces that are made out of mostly glass.

Because they are a family-run business, they are very transparent with their staff and their respective roles in the firm – an aspect that we find quite admirable. Ideal Windows and Conservatories also claims that 68% of their projects come from recommendations.

That said, they have a 10-year warranty for clients, but some have reported having experienced poor after-sales service. Although there aren’t many of these cases, we still advise readers to do research and exercise caution when choosing a service.

We also hope that Ideal Windows and Conservatories continues to take these comments and claims to further improve its relationship with clients to continue being one of the top window replacement companies in Edinburgh.

  • Specialisation in installations, refurbishments, and designing
  • Jack-of-all-trades company with a vast number of services
  • Customers don’t have to provide a downpayment


  • Not the cheapest option around
  • Not the most efficient installation process

Finally, we have Bryant and Cairns Windows and Conservatories – a service-focused business that doesn’t quite fit the stereotypical image of most double-glazing companies. They specialise in installations, refurbishments, and designing for clients.

The company claims to combine 120 years of experience in the home improvement market as one of Edinburgh and Lothian’s premier home improvement specialists. They’re a jack-of-all-trades to some degree thanks to their many services.

The company can handle casement, tilt & turn, reversible, sliding sash, and even patterned glass window installation and double glazing. Similar to Ideal Windows and Conservatories, you can also have them construct conservatories and extensions.

We also appreciate that they don’t require clients to pay until installation is complete, which can be a relief to those who are worried about wasting a downpayment for bad work quality.

We have to point out, however, that they aren’t the cheapest option around. We’ve also noted some reports involving faulty installations – which have been fortunately resolved in the end, after a few visits.

However, these instances are important to keep in mind, especially for customers who value efficiency above all else. If you’re looking to get several renovations done at once, Bryant and Cairns Windows and Conservatories is still a great one-stop shop.
