what clients say about us
Wow Wow Wow !!! The new windows and sliding door from WindowTech far exceeded our wildest expectations! The quality and value were beyond compare. From initial visit and estimate with Leon where we felt heard and were not oversold, to the final fitting and measurement by Vlad to installation day… the journey was so seamless and stress free. Installation and custom onsite fabrication by Vlad, Alex, Jackson and Igor was flawless. These guys work SO hard and get it right. Even after long hot day, they left the site spotless. I recommend highly. You gotta go WindowTech ! We are so delighted with the end result.

We are more than satisfied with our new windows from WindowTech. Their sales rep. Dmytro was clear, courteous, straightforward and quickly responsive to any questions we had along the way. The installation was efficient and problem-free and the windows are exactly what we expected at a fair price. I highly recommend WindowTech.

This is our 2nd time using WindowTech and they delivered again! This time was for a new side door/entrance. He came. He did. He cleaned up. He left. Done.
Value = quality work in a timely manner at the right price. The first job was a complete main floor window replacement and new patio door for the master bedroom where only a window existed. 10 out of 10 on that one too!

Frequently Asked Questions
When is a good time to replace old windows or doors?
There are a variety of signals that all homeowners should be aware of, indicating that it is time to replace your existing windows or doors:
Increasing energy bills could indicate that your windows or doors are not fulfilling their role as thermal control mechanisms, either from loose frames or a lack of water/air tightness in insulation. Windows should prevent drafts and air leaks, and if either of those appear, it is time for a replacement.
Visual and aesthetic signals are often the most evident of all, including broken or cracked glass, peeling paint or frail and weakening aluminum. Rotting frames are also one of the best indicators, since a poor frame can dispel all the advantage of even the best-quality window, including superior insulation and security.
The formation of ice or frost on the windows signals condensation build-up from rapid changes in temperatures. This often occurs when low quality or weakened insulation and thermal materials allow air to infiltrate too quickly with rapid changes in temperature.
How long will the installation process take?
Most installation projects will take 1-2 days; however, for porch enclosures or very-large scale replacement windows projects, up to 3 days may be required.
With that said, all of our customers can be sure of clean and non-intrusive installations with dust rugs being used at all times to protect your floors. All garbage and debris will be removed upon completion of the day’s work.
Why is vinyl considered to be the best material for windows and door frames?
Vinyl is highly favored as a material for windows and door frames, and this preference stems from several significant attributes. Its energy-efficient nature is underlined by its superior insulation capabilities and the potential to shape it into multi-chamber frames, enhancing thermal resistance.
Durability is another strong suit of vinyl; it stands up to damage, such as chipping, peeling, or cracking, and remains unchanged in color despite sun exposure or severe weather conditions.
Additionally, its low-maintenance requirement, with only basic cleaning using soap and water, adds to its appeal. Summarily, vinyl, with its strength, energy efficiency, and ease of maintenance, is an outstanding choice for windows and doors. Easily cleaned with soap and water, it is virtually the lowest-maintenance material available for windows and doors to date.
What makes a window or door energy-efficient?
Windows are considered to be energy efficient when the frame is made of high-quality material such as 100% extruded vinyl, when the glass is made of multiple panes filled with insulation gas such as Argon, when Super Spacer technology is present, and the glass is coated with Low E or Low E 2 coating which reflects the heat.
Doors are considered to be energy-efficient when the core of the door is insulated with foam, the composition material is solid, the frame is a tighter fit to the spacing, and multi layered weather stripping is used.
