The Most Reliable Windows and Doors Stratford Has to Offer

Living in Perth County means your home is regularly exposed to seasonal extremes, from harsh snowbelt winters to hot, humid southwestern Ontario summers. Because of this, your home is naturally more susceptible to issues such as failing weatherstripping, degrading seals, drafts, and moisture entering your home, which can force heating and cooling systems to overwork and raise energy bills.  

Replacing your windows and doors can make all the difference. At Clera Windows + Doors, we manufacture quality products designed to withstand extreme Canadian weather without warping, rotting, or leaking. Our windows/doors feature 100% virgin uPVC, delivering industry-leading insulation, durability, and long-lasting performance. With upgraded features like triple-pane glass options, your Stratford home is guaranteed to be protected for 30+ years.  

Work with Clera Windows + Doors and get professional window/door installation services backed by a non-prorated transferable lifetime warranty.

Frequently Asked Questions

How much does it cost to replace windows in Stratford?

Down Arrow Icon

The cost of replacement windows in Stratford depends on the style, size, and glass package you choose. Standard options like hung, slider, and fixed or picture windows generally start around $800 per unit installed, with bay or bow windows at the top of the range due to the extra materials and structural work involved.

Because we manufacture everything in-house, we can offer factory-direct pricing without the markup you'd pay through a third-party retailer. Contact your local Clera representative for transparent pricing or schedule a free, no-obligation in-home assessment.

Can Clera match the historical style of my house in Stratford?

Down Arrow Icon

Yes. Many of Stratford's most recognizable homes are Victorian-era properties near the downtown core and the Avon River, and we regularly work with homeowners who want to preserve that character.

Clera offers a wide range of custom grid patterns, frame profiles, and colour finishes to match your personal preferences and your home's appearance while still delivering the energy efficiency, low maintenance, and security of modern replacement windows and doors.

Can door installation in Stratford be completed in the winter?

Down Arrow Icon

Yes. Clera offers windows and doors installation Stratford homeowners rely on year-round.

Our installation crews are trained to work efficiently through Ontario's coldest months. The best part about replacing windows and doors in the winter is that there’s way more availability and flexibility in scheduling. Contact us to learn more!
