About Us

A local

DuoTemp Home Improvements has been helping Canadian homeowners in the Niagara Region for over 60 years. In that time we have seen a lot of change in the exterior home improvement industry and rapid advancements in the technology and products available – all for the better of homeowners!

Exterior home improvements

From single window replacements to complete architectural overhauls we are well positioned to deliver exceptional products and installation at competitive prices. We have access to a variety of Canadian suppliers and are a certified Gentek Premium Renovator. The core of our business comes from replacement vinyl windows though we also specialize in Entry & Patio Doors, Awnings and Sunrooms.

Exceptional service top to bottom

We’re proud of our reputation as an honest and reliable local business. Our success has come on the backs of our wonderful staff – many of whom have been with us for more than twenty years.

A brief summary of DuoTemp’s history:

  • Founded in 1946 by J. Budney who left Hayes Dana to found a local home improvement company.
  • Located for 11 years at 16 Ormond Street in Thorold, Ontario.
  • Manufactured and distributed storm windows and doors, siding, aluminum awnings, enclosures and other home renovation products.
  • In 1960 moved to our longtime location at 105 Merritt Street, St. Catharines.
  • In 1973 we began the assembly of thermopane windows.
  • In 1976 we expanded operations and added a new warehouse addition.
  • In 1977 we began the manufacture of 1 1/4” and 2” aluminum storm doors.
  • Under the ownership of Bob Allen the company grew both in size (employing approximately 30 people in office, sales, assembly and installation functions) and reputation for doing a great job for a great price.
Today, we’re still as committed as ever to evolving our business, products and services. Our showroom on Merritt Street is no longer open as we streamline our service and offer the in-home consultations so many customers appreciate.

Now owned and operated by Bob’s longtime sales and installation righthand men, Rob Ward and Frank Minaker, very little has changed in offering the best replacement windows and doors in St Catharines and the surrounding area!

As a DuoTemp customer, you can rest assured we’ll always stand behind our work and be here now, and for generations to come.
