I contacted Brock Doors & Windows Inc. after seeing their ad on a flyer with a 30% end of summer sale. After three other assessments and quotes from different companies, Walter was very informative and was not pushy like the other two associates or aloof like the first company I contacted. Afterward, Eugene came for the second measurements and we knew our project was in good hands. He was very knowledgeable about what his plan of action was and where he might have difficulty with our old house where nothing was ever straight or square. The installation date came one week sooner than we anticipated, just in time for the colder weather. Eugene and Asror were very thorough, efficient and considerate of our home's cleanliness. They used drop cloths, an h-vac, and garbage drums and did their best to clear their work site of debris and dust. A few minor details include dirty hand prints on the walls around work sites and nicks on our newly painted front porch. Not an issue given the nature of the job, ie. heavy lifting, etc. Most importantly, they were able to save the stained glass window above our main floor big bay window, hopefully to be hung on display at a later time. All in all, we are very happy with the job done. It was exactly as quoted at one day and a half. The windows and doors look fantastic and it's like we're in a new house. Looking forward to our first draft-free winter since moving in 2011. We would definitely recommend them to family and friends. In fact, several neighbours asked for their info while on the job on day one. Seven retrofit white North Star windows (triple-paned argon gas) and two patio doors for $8,500? Heck of a deal! Despite being based in Brampton, we appreciated them coming to Toronto's west end. All the best, guys!
