Outstanding Service and WorkmanshipWe recently had the glass in our home windows replaced and upgraded to double glazing through Retrofit Double Glazing, and we couldn’t be happier with the experience.The professional nature of the company was evident from our very first contact with Warren, through to Jarrod, who carried out the measuring and provided the quote, and our installers, Liam and Eddy. The entire process went seamlessly from start to finish.A special shout-out to Liam and Eddy, who took great care in the way they worked in and around our home. Their extremely high level of workmanship, attention to detail and professional manner gave us complete confidence in the work being carried out. They were respectful of our home and left everything neat and tidy.We also appreciated the follow-up communication from the company, keeping us informed about when the work would be carried out. This gave us peace of mind and allowed us to plan ahead.We would highly recommend Retrofit Double Glazing to anyone considering upgrading their existing windows. From the initial contact through to completion, the service, communication and workmanship were exceptional.A fantastic experience from start to finish!

Brilliant job from start to finish. Easy quoting process and staff helpful. On the day the team arrived promptly, and introduced themselves. Valentin and Jasmin were very professional, polite, and eager to make the installation experience positive. They are a great team! Work completed in a timely manner, windows look wonderful, and they cleaned up before they left. Communication through the day as the job progressed was wonderful. Thanks so much.

A Home Renovation That Pays For Itself

When Melbourne homeowners plan renovations to add value to their home they often look to kitchen or bathroom upgrades or extensions. Upgrading your windows from single-glazed to double-glazed is often not at top of mind but is a home renovation that can provide immediate lifestyle and cost saving benefits.

Retofit double glazing improves your home in ways that are appreciated and sought after by home buyers. Upgrading to double glazed windows lowers energy bills, creates a quieter and more thermally comfortable home and reduces condensation on windows during Melbourne's colder months.

Why Double Glazing Stands Out as a Home Renovation

Not all home renovations appeal equally to prospective buyers with personal style and taste playing a significant role in how they are valued.  Double glazing delivers quantifiable improvements to a home that appeal to a wide range of buyers: 

1

Up to 75% reduction in heat loss

Meaning lower heating and cooling bills and a more even and comfortable in-home temperature

2

Up to 70% reduction in external noise

Making homes quieter in Melbourne's bustling urban suburbs

3

Reduction in condensation

Minimises condensation forming on windows during colder months, protecting original timber frames from long-term damage

4

Preservation of original window frames

Maintaining the character of period and heritage homes

Retrofit double glazing is particularly valuable for heritage and period homes in Melbourne.  It  allows homeowners to improve thermal and acoustic performance while retaining the original character and charm of the home, which is often a key selling point.

A Smart Upgrade Before Selling a Home

Upgrading windows before listing a property allows homeowners to add a marketable and high-value feature. It is also a renovation that is backed by a lifetime workmanship warranty and a 10-year IGU warranty, giving prospective buyers additional confidence in the quality of the installation.

 

Double Glazing: A Renovation That Benefits You Now and When You Sell

The best home renovations improve your life today and your return tomorrow. Retrofit double glazing does both. Every year you remain in your home you enjoy the comfort and savings. When the time comes to sell, those improvements translate into a stronger result at auction.
