Wow, this is by far the best window company in Canada (IMHO)! First, the windows are technically advanced far beyond ordinary windows. They look much better, insulate better, and offer the most amazing security features.
After researching a number of companies, and getting quotes from four different ones, we went with House Tune Up (Dako Windows from Europe). Here's the main reason: our next door neighbours demolished their home and rebuilt a nice new one. During the construction, they had some building supplies removed from the job site late at night. So my neighbour Mark put up some security cameras.
A few weeks before they were to move in (but after the appliances, etc were installed), they had an attempted break-in early one morning. The man was caught on film throwing large rocks, using a big hammer, and finally trying a crowbar to open the door. Although the door was bent slightly from the crowbar, it didn't open. After 22 minutes (on film), the man left empty-handed. Watching the video, even the police couldn't believe how the Dako product thwarted the attack.
The second sell point is their pricing. Although they weren't the cheapest quote, they were much less than two other companies, for a product that is clearly superior.
Third, these window look incredible and operate perfectly. Plus they can be super-wide, giving a more pleasant view of the outside.
Lastly, the customer service at House Tune Up is top-drawer. Although there's a fairly long lead time since they're coming from Poland, once they arrived in Canada, the delivery went very smoothly. The installation went more quicker than they estimated and they're follow-up service was excellent.
Since you've read this far, you're clearly interested in getting the best windows you can buy, at a fair price. You just found them! I encourage you to get quotes from other companies, then compare quality and pricing, and I'm pretty sure you'll make the same decision we did... House Tune Up! Five Stars, 10 out of 10, two thumbs up.
