There can be two types of moisture that collects on windows in Welland, either condensation, or rain and snow from outside. In humid areas like Welland, moisture from the air tends to form water droplets on cool surfaces like glass. Rain or melted snow can also enter the home from the window edges and accumulate along the window. In severe cases, the water will lead to water damage.

Vinyl Windows & Doors

Vinyl is Clera’s preferred choice of material ahead of wood because years of experience fitting windows and doors throughout Welland have taught us that there is nothing better. Clera only uses 100% virgin uPVC which is incredibly lightweight and very hard-wearing. There is a wide range of thickness options meaning you don’t have to compromise when it comes to the style of your choice. Not only does vinyl tick all our boxes but it is incredibly priced so it is bound to suit your budget.

Clera offers vinyl in an amazing spectrum of colours but if you really can’t find what you want then we do offer a personalised paint service. Vinyl is high up on the list of great insulators and so you know you are doing your bit for the environment whilst shaving cost off your heating bills. It is lightweight so easy to open, close and adjust the window units and doors. Vinyl is low maintenance although the finish is so super shiny and durable that people will think you never stop cleaning. In fact, the reality is quite the opposite.
