Commercial Glazing

SGC Glass is a specialist commercial glazing contractor with 30 years of experience delivering glazing projects for offices, retail units, schools, hospitals, leisure & hospitality venues and new build developments. We provide a complete commercial glazing service covering London, Essex and the wider South East.

What Is Commercial Glazing?

Commercial glazing refers to the installation, repair, and replacement of glass systems in non-residential buildings .Unlike residential glazing, commercial projects involve larger-scale glass solutions designed for durability, energy efficiency, security, and aesthetic impact. From sleek curtain wall systems and structural glass facades to frameless entrances and high-performance insulated glass units, commercial glazing plays a critical role in a building’s appearance, functionality, and long-term performance.

It can include everything from shopfront glazing and glass partitions to fire-rated glass assemblies and high-level window replacements on multi-storey buildings. Unlike residential glazing, commercial projects typically involve compliance with stricter Building Regulations, tighter programme schedules, coordination with other trades, procurement requirements and strict regulations around health and safety which often requires various industry accreditations.

I recently had some work done by SGC Glass Ltd. The Maintenance Engineer arrived on time and started examining the problem I had with a door. He was very thorough and when he found the fault he fixed the problem and cleared up any mess. I recommend SGC Glass Ltd.

We used SGC Glass for a commercial glazing project at our premises and were thoroughly impressed from start to finish. The team was professional, punctual, and clearly experienced in working within a business environment.
Minimal disruption was really important to us and they absolutely delivered on that. Communication throughout was great; we always knew what was happening and when. The quality of the finished work was first class, and the pricing was competitive.

We'll definitely be using SGC Glass again for future projects.
Response from the owner:Thank you so much Lewis, for taking the time to write a review. We really do appreciate this. We are so pleased to hear of your positive experience – we strive to always deliver our best!

I contacted SGC Glass for information surrounding an installation. This installation was not carried out by them. Although they were unable to assist, Steve made contact with the manufacturer and provided contact information of a company who was able to assist. SGC Glass went above and beyond to provide support and even checked in to see how things were progressing. Extremely friendly and caring staff. Thank you Steve and Charlie.
Response from the owner:Sabrina, thank you so much for taking the time to write this review, especially as we weren’t able to carry out the installation ourselves. It means a lot to us that you’ve done so. We are really pleased to hear that our staff have provided you with a friendly and caring service. We will be sure to pass this feedback on to them. Thanks again.

I cannot recommend this company enough. We were faced with a tricky glass replacement that most companies I tried turned down as they couldn’t source the glass to the size and spec we needed. And thought it would be a difficult job. SGC took the job on without hesitation, sourced the glass and fitted it without a hitch. Everyone I dealt with was professional and helpful.
Simply amazing and we couldn’t be happier.
Response from the owner:Hello Catherine,

Thank you so much for your review – it means a lot to us! We are so happy that you are pleased with our service. We will pass on the feedback to the rest of the team.

We are a timber window manufacturer and recently approached this company as our current glass supplier was unable to offer the product we required. Paul Boxhall went above and beyond from start to finish, to not only supply the products but also deliver direct to our customer. I have had feedback that the delivery driver was also super efficient and very polite.
Great company to deal with, smooth sailing from start to finish. Definitely recommend to all.
Response from the owner:Thank you Welsted Joinery for your review. Your feedback really does mean a lot to us and to our staff. We are so happy that you were pleased with our service and we look forward to working with you in the future.

We had one window fail on us so decided to have all 8 very large windows replaced. This required them bringing in a large crane and a track machine. Tom and the guys were Professional from start to finish. They worked continuously. The weather was atrocious, wind and driving rain. They completed the job in the timescale given, without any mess and kept us informed throughout. Would highly recommend SGC Glass.

We wanted to replace a back door, more in keeping with the style of our house. Ellis was very knowledgeable, as we decided on the design of the door and in finding one that would fit the smaller than normal opening.

Chris, who is very friendly and helpful, who installed the door was excellent, as taking out the old door without damaging the exterior render was not straight forward. But he managed to do it with just minor damage, which he repaired it once the door was fitted.

We’re very pleased with the final product and Chris went the extra mile to make sure the small details were done well.

We’d recommend SGC to others, and are waiting a quote for some further windows from them.
Response from the owner:Thank you so much for your review Andrew. We are so pleased that you were happy with our service and we look forward to assisting you again. Many thanks for your custom.

I had two interior glass panel replaced with clear laminated glass.

Our Commercial Glazing Services

New Installation – We supply and install glazing systems for new build commercial developments, working alongside main contractors and developers to deliver windows, doors and curtain walling. We work with trusted suppliers to control specifications and keep lead times competitive across each project.

Replacement Glazing – Full replacement of failed, damaged or thermally inefficient glazing units across commercial buildings. We supply sealed double and triple glazed units through trusted suppliers, with all replacement work specified to meet current Building Regulations requirements such as energy efficiency, fire safety, security, occupant safety, structural performance, weather resistance, acoustic control, and accessibility.

Glazing Repairs – From cracked panes and blown sealed units to failed ironmongery and damaged frames, we carry out targeted glazing repairs that restore the integrity and appearance of commercial buildings without unnecessary full replacements.

Emergency Callout – Emergency commercial glazing response covering London, Essex and the South East. Our rapid response service includes emergency glazing, boarding-up, temporary glazing and permanent replacement. We understand that a broken shopfront or smashed office window is a security risk that cannot wait.

High-Level Glazing – Specialist high-level and high-rise glazing work using MEWPs, scaffolding, rope access, spider cranes, truck-mounted cranes and vacuum lifters. Our operatives hold IPAF and PASMA certifications and are harnessed trained for safe working at height. This capability sets us apart from many commercial glaziers who lack the equipment and training to work above ground floor level. Our project at Royal Ascot Racecourse is a strong example of this specialism: a high-profile, technically challenging job involving specialist access equipment.

Shopfronts – Supply and installation of aluminium and frameless glass shopfront systems for retail, hospitality and commercial premises. We glaze with laminated anti-bandit glass, with options for toughened safety glass where required. All our shopfront systems are expertly designed and installed to the highest standards, featuring energy-efficient, secure, and safety glass for superior performance, lower running costs, and maximum protection.

Glass Partitions – Frameless and framed glass partition systems for offices, meeting rooms and commercial interiors. All our glass partition systems are designed and installed to create modern, flexible workspaces that maximise natural light while providing excellent sound insulation and privacy where required, along with manifestation and branding options for safety and visibility.

Replacement Of Fire-Rated Glazing – Supply and replacement of certified fire-rated glass that acts as a barrier against smoke and fire. Fire-rated glass is rated for integrity, its ability to stay in the frame when exposed to fire, and many products also carry an insulation rating, the ability to stay cooler on the side away from the fire.

Balustrades – Frameless, post-mounted or spigot, clamped or hand-rail mounted glass balustrade systems for commercial interiors, mezzanines, staircases and external terraces. All balustrade glass is specified to suit the barrier loading requirements of each location, using either toughened or toughened laminated glass.

Secondary Glazing – Internal secondary glazing systems for listed buildings, conservation areas and properties where external alterations are restricted. Secondary glazing delivers measurable improvements in thermal and acoustic performance without changing the external appearance of the building.

Aluminium Windows and Doors – We supply and install aluminium windows and doors for commercial projects, and fitted by our own glaziers. Every project is delivered under our direct responsibility and control, with full accountability from initial survey to final handover.

Sectors We Support

Our commercial glazing services cover a wide range of building types and sectors across London, Essex and the South East:

  • Offices including multi-tenant commercial buildings, corporate headquarters and serviced office spaces
  • Retail from individual shop units to large shopping centres
  • Hospitality including hotels, restaurants, bars and leisure venues
  • Education covering schools, academies, colleges and universities, with DBS checked operatives and the ability to schedule works around term times
  • Healthcare including NHS facilities, private clinics and care homes
  • Leisure including gyms, sports centres and visitor attractions such as Royal Ascot Racecourse
  • Industrial covering warehouses, distribution centres and factory units
  • New build developments working with main contractors and developers on residential and mixed-use schemes
  • Facilities management portfolios providing planned and reactive glazing services across multi-site property estates

Building Regulations and Technical Compliance

All commercial glazing installations carried out by SGC Glass comply with current Building Regulations. For thermal performance, we specify double and triple glazed units with appropriate gas fills, warm-edge spacer bars and low-emissivity coatings to meet the required standards. Where projects call for improved acoustic performance, we specify laminated acoustic interlayers to reduce sound transmission.

Safety glazing in critical locations is specified and installed using toughened or laminated glass depending on the application, in line with current Building Regulations. Fire-rated glazing assemblies are installed strictly in line with their tested configurations to maintain their certified fire protection rating.

As a FENSA registered company, we self-certify compliance on residential window and door replacements where applicable.
