Our windows and doors were made of wood and rotting, so needed replacement. However the interior trim of was quite unique and we wanted to preserve the look. After getting quotes from many other companies, we decided to go with Casa Bella, as they had the most competitive price and best reviews, and Ronnie, our sales guy, assured us that they could make the windows look exactly the same from the inside as they did before replacement, and that we could keep our existing blinds.
We wish that he hadn't made this promise, because in the end the windows could not look exactly the same, and we had to replace all our blinds (which of course added another 10K to the project).
The installation crew was fantastic, very professional and fast. They found a rotting water situation in one of our walls and did a great job fixing the problem. Some of the window trims had large caulking stains on the walls around the windows which was a bit disappointing, and as I was patching up the indoor trim to paint I found several sharp wires/nails sticking out of the trim, which was a bit concerning given I have small kids at home. However, I have no basis of comparison as this is the first time I've had windows replaced, so I don't know if this is the standard.
Final criticism is this - I got the Classic line of windows, and after replacing all of our windows and most of our doors, we ended up using more natural gas for heating our home this winter, even though our schedules/lifestyles have not changed and it was 25% warmer this winter than last year. I'm not sure if this is related to the window insulation or not, but I was told by the installation crew that I should expect a very noticeable savings in our heating and cooling bills which didn't happen.
Despite these failings, our windows are now painted and look stunning, and I am hopeful we won't have any more rotting and leaking issues. I would likely use Casa Bella again in the future if needed, but would just try to temper my expectations and take their promises with a large grain of salt.
