Welcome to Siderite Plus (1997) Inc.

Formally Siderite Plus Inc, we have a combined 14 year operating history with the principle previously owning and operating wholesale building product distribution warehouses for 10 years, and prior to that spent 15 years in manufacturing and distribution of vinyl building products.  We know the business!

Siderite chooses to be a small to medium sized home solutions contractor restricting it's trading area to roughly a 30 mile radius of London.

We concentrate on supplying and installing vinyl replacement windows, vinyl siding, soffit, fascia and trough, as well as roofing.  Siderite also welcomes bathroom and recreation room projects, and sidewalk, deck and driveway work.

Many years of wholesale and retail experience has enabled us to  fairly judge various product offerings and align ourselves with some of the very best manufacturers of quality products that are proven performers with strong warranties.

We use VWD  and  Northstar vinyl replacement windows, Mitten vinyl siding and designer accessories, Dorplex steel doors, and G.A.F Roofing systems, to name some of the more prominent.

Our manageable size and knowledge enables us to provide personalized service. Management visits each and every job while  in progress, to ensure a smooth installation.
