Our Step by Step Process

Step 1: Free Consultation & Measurement

Our Reliant Windows & Doors rep will advice regarding which window types will be best for your home and family. For example, if you have young children, you will not want to install windows that are too easy for them to open and fall out of. If you live in an area that has a lot of rain and snowfall, we may recommend awning windows that will still allow airflow during inclement weather. After picking the types of windows you want, our rep will take down the measurements as well.

Step 2: Installation Assessment
Step 3: Preparation

Once the quote is accepted, our Reliant Windows & Doors installation team will schedule a date and time to remove and install the new windows. Before the installation team's arrival, please remove any window coverings and furniture so that the installation team has plenty of room to work.

Step 4: Removal & Installation

Our Reliant Windows & Doors installation team will arrive on time with the products that you've ordered. We will then remove the old window and insert the new one. If you have time on the day, feel free to stick around and watch our installation team does their magic.

Step 5: Project Walkthrough

Once the installation is completed, our installation team will conduct a walkthrough with you to make sure you ae happy with the work done!

What People Say About Our
Barrie Windows & Barrie Doors Services

  • Mckenzie Betts
    The installers for Reliant Windows were very nice and did an excellent job cleaning up. During installation, a supervisor stopped by to check in with us to be sure everything met our expectations. Unfortunately, it was after they left that I noticed a few screens that didn't completely meet the sill and left a small gap. With no problem, they set up an appointment to inspect and subsequently reordered frames and fixed the problem. Needless to say, we would recommend this Barrie window company based on this great customer service. And, of course, we love how our end vent slider windows look! null

    I love the clarity of our new windows from this Barrie window company! We had a great team come to put the windows in. There was one small issue afterward, but they came right out and adjusted something on our newly installed single hung windows. We just got the windows this month, so we don't know if we will see a reduction in our utilities, but we hope so, with going from old single pane to double pane windows. We have been very pleased with customer service with Reliant Windows! null

    The workmanship and quality of the awning windows I got installed are amazing! The crew at Reliant Windows was truly professional and off the charts with knowledge of their product. The whole process was just amazing and was done with no pressure from the salesman and his service was awesome. The office workers were awesome and made everything easy to take care of and never once was there an issue with communication to me or the installers and billing. I love this Barrie window company! null

    They just finished up our house today, and I can’t recommend Reliant Windows enough!! From start to finish, I’ve been informed, given exactly what they were going to do and the cost. They provided me ahead of time what we needed to have done before their arrival and the install crew was very nice, courteous and respected our house and belongings. We were originally scheduled for a few weeks away- but they called and advised our product came in early and a crew was available today. The installation of my casement windows look amazing! If I could I would rate my experience it would be at the highest possible score! I will definitely recommend them to all of my friends and family and I hope this review will help whoever is reading this with this decision. This is the go-to Barrie window company! null

    When we used Reliant Windows, everything through the process was easy. The employees were friendly and knowledgeable, the windows arrived in the appropriate time frame. Customer service was quick and efficient for any questions I had. The installers were so nice and voiced their opinion for the trim. They said it would look better with a thicker trim because of the ledge the garden window I ordered sat on. I agreed and they went right to work to finish up the installation properly. I am SO incredibly happy with all of it. I had been wanting to get new picture windows and bay windows for years! This Barrie window company is the best! null

    I absolutely love Reliant Windows! I have used them several times. We used to flip houses. We had them installed in those houses as well as our own house. You can’t beat them for the price and quality of the windows. The customer service is great too. One of my windows had a seal leaking that let condensation in. The casement window was about 7 years old at that time. I called and they came out right away to replace it. The crew noticed a small hole in my screen and replaced it too. I have referred Reliant Windows to others and they have been very pleased with this Barrie window company! null

    Customer service at Reliant Windows has an immediate response. Their salesman came right out, helpful and I got a quote right away. Installers went above and beyond- told us what to expect, cleaned up everything fast, friendly, ask before moving anything, and came back right away the next day to finish. Highly experienced and installation of my double hung windows was done right. We love our new windows! Now our house is warm, quieter, and windows open and close easily. We highly recommend this Barrie window company! null

    After years of trying to decide on new windows, due to all the horror stories that I had heard, of overpricing and below standard installations, we made the decision to talk to Reliant Windows. After scheduling with the salesman to come out and give an estimate, the decision was made to go with this Barrie window company. Everyone involved was extremely friendly and professional. The installation crew was awesome and all finish work was of the highest standard. We are very pleased how our single hung window installation turned out and we're thankful to this great company. null

    We are so happy with our experience with Reliant Windows from start to finish. Seriously, this is an honest review. They go out of their way to make their customers happy. The windows alone are just beautiful! We must have about a 90% noise reduction. We had 6 windows replaced including our bay windows and end vent slider windows. Our previous windows were original to the house and single pane glass that let the outside in so our interior environment now is cool and quiet. The installer was a true professional and had no problems answering questions and the cleanup was spotless. Do not hesitate to get an estimate for your home because the window demo is really impressive! I highly recommend this Barrie window company! null

    I recently contacted Reliant Windows to redo the windows in my home. I needed to have 10 windows replaced. I had casement windows, single hung windows and double hung windows installed. The team arrived in a timely manner and introduced themselves to me. They explained the process and that the job should be completed around 5:30 PM that afternoon. They went to work and were very efficient. The new windows were neatly set in place after the removal of the old ones. After completion of the task, they removed all trash. Everything looked outstanding. The windows have greatly improved the home's appearance. I have The job was completed at least one hour earlier than the projected time. I am satisfied with this Barrie window company! null
