Ostaco Windows And Doors

We renovated our home with Ostaco windows and doors. I am extremely satisfied with their product. We noticed a big difference in our heating and air conditioning bills. We have received lots of compliments on the product. We would definitely recommend Ostaco.

We purchased our “retirement” fixer upper near Dorset Ontario. The first project we tackled was all new windows and doors. We chose to go with Ostaco because they were able to customize our order and had the quality we were looking for. The sales rep made some great suggestions including using different LowE coatings on different elevations of the house to maximize energy efficiency. What a difference, the house is always comfortable and we have noticed a big difference in our heating and hydro bills. The new windows and doors have completely transformed the look of our house, we frequently have people stopping to ask where we got our windows and doors. I wouldn’t hesitate to recommend Ostaco windows, it has been the best investment we have made in our home.

I have changed my review for ostaco windows and doors ...the new sales rep showed up herself with a glass for my entrance door and apologized for the mix up between them and h.hardeware ! She was no time swapping it out for a clear glass until they get my privacey glass fixed AND took the time to have a look at my single hung window and repaird it from 8yrs ago when the salesman just left me the pane to replace it myself !! THANK YOU Christine for takeing the time to get this resolved !!

Built a new house in 2018. Used a reputable general contractor (who did a great job). I wanted good quality windows and doors, but because of the size of our job (25 windows, 2 triple sliding doors, 1 entry door) I was looking for a mid-range priced product to fit my budget. Ostaco was one of the options suggested to me as a good mid-range product. The build was finished in August 2018. I had one issue immediately which was that a lot of the metal crank handles on the windows were cracking. Ostaco's service tech John came out and replaced all of them, and he also found some other issues that I wasn't even aware of (missing components on the front door). As a customer, this was a good experience. Then in the fall, I noticed leaves, pine needles, and other debris on the kitchen floor which was odd because all doors and windows had been closed. Upon closer inspection, discovered that the door when closed had a 1" opening to the outside because it was missing some components (impervious block and dust pad). The opening is large enough for leaves and debris from outside to blow into the house, along with cold air. A mouse can easily squeeze in through a 1" opening. I reported the problem on Dec 5th. Their customer service manager said on Dec 6th that a service call might not be possible this month. On Dec 20, I hadn't received any update from Ostaco, so I followed up with the customer service manager again, and was told that a service call hadn't been scheduled yet and was unlikely to happen until late January. Making a customer wait for 1-2 months in the winter time to fix a door that leaves a 1" opening to the outside when the door is closed is simply unacceptable.

We are a general contracting firm that has used Ostaco on approximately 30 jobs over the last 5 years. They have always been very efficient and professional to deal with. Their jobs have always been completed on time and on budget.

I would also say that the windows are great value and that you cannot beat the quality for the price.

I would highly recommend the team at Ostaco windows.

Purchased a 12ft patio door. Cheap construction. Very drafty. Cold comes right through. You can hear everything outside. LoE 272 tint is minimal. Installer sent by company President did a lousy job. Calked over expanding foam while still expanding so the calking on exte​rior is uneven and full of bubbles. To lazy to come back next ​day and do the job properly.
Stay away from this com​pan​y. Regret purchase terribly and obviously don't recommend.

UPDATE: Note that even Ostaco knew my name as directly published on this site and having me in their customer database, they still challenged HomeStars to remove my review. In an effort to defend my review, I submitted the bill of sale direct from Ostaco Factory as proof to HomeStars. Regarding their reply to my review, its simply Customer Service Spin. The company has been in business since 81 however has changed hands / management along the way (see their online posts). The defence of not selling to the public is irrelevant as it does not change the product quality all though not applicable in my case anyway.

At 8 months old, the welds around the vinyl weld joints have now all cracked. See photo.

Updating my review below that I left about 2 months ago (mid October) about Ostaco Windows. We were previously quite frustrated trying to get repair work done to a set of exterior windows. But I am happy to say that Ostaco followed through and took care of our issue.

I was actually contacted directly by their General Manager, Marco Greco, who acted with great integrity and customer care. He personally came to our house to inspect the windows. He kept us informed with updates. And most importantly, he followed through... sending an experienced, knowledgeable and respectful service technician, who completed the repairs in about an hour.

At the same time, Marco acknowledged where the company fell short, but assured us that our experience was not their standard, and his priority was to "make things right". And he did.

Ostaco is a small, family-run business, and he clearly cares deeply for their reputation and product.

I have left portions of my original review below, but have chosen to temper it in light of the turnaround in service we received.

_____________

Been reading the reviews posted for Ostaco Windows and their not-so-great service when it comes to warranty repairs. So I felt compelled to add our story.

The seals on our exterior large panel windows at the back of our house have been failing. The company sent a technician to inspect the damage, and they say the issue is with the sidelites due to exposure to the sun and not having an overhang. Ostaco are covering the cost of the materials and we have to pay for labour, estimated to be $350.

Dealing with Ostaco's Service Manager has been an exercise in patience and frustration. Email communication back & forth has been difficult. It's been a challenge to get an hourly breakdown of the $350, a formal estimate in writing or a contract for the repair work. Regardless of how we ask, we continue to hit a wall getting answers.

I should add that we opened our claim with Ostaco beginning of July. It's now mid October with no resolution or repair date in sight.

We replaced all of the old windows in our cottage with Ostaco windows that are triple pane with two low-e surfaces on the glass and argon, and it's made such a difference to our level of comfort in the cottage as well a significantly improving its appearance. It used to get so hot in our cottage in the summer and it's so much cooler now, it almost seems like we have air conditioning when we don't! It's going to be awesome to have far lower heating bills this winter. We would highly recommend Ostaco to any looking to replace their windows.

I’m actually easy to please. Supply a good quality product. Install it properly. If you make a mistake, fix it quickly on the first try. Ostaco is incapable of doing this. Even though the windows themselves are fine, I would never recommend this company because of their lousy screens and poor customer service.

Ostaco used a poorly designed system for the screens (think cheap and flimsy). If you take the screen out of the window, even a few times, you can expect the mounting pins to come off. That leaves a gap on one or more corners, which bugs find quickly. If the window is open and exposed to good gust of wind, the screen can pop out because the mounting system is so weak. I have a nice gouge in my hardwood floor where one landed on its corner.

They tried many times to fix the problem screens. The catch is it can take months for the technician to show up; it’s at their pleasure and convenience, not yours. He tried three times at least to get the ones in the bedroom right. They were either too tight or too loose. The last set are so tight that I can barely pull them out, using extreme force. I leave them in permanently because they’re sure to break if I remove them.

In her last email before she stopped responding, the service manager told me they’re done: it’s out of warranty, tough luck. Apparently it’s my fault that their screens are garbage and their technician can’t measure a screen properly.

We had a great experience with Frank Greco and his team. Will recommend to our clients for future projects.
