Straight Answers to Common Pricing Questions
Why do quotes from different companies vary so much?
A low quote often leaves things out, like removal, proper sealing, permits or a real labor warranty. A high quote is often an inflated price with a "today only" discount on top. Always ask what is included so you are comparing the same project.
Are you the cheapest option?
No, We are not the cheapest and we are not hte most expensive. If you are flipping a house, selling soon, or want the lowest price no matter what, we are probably not the right fit, and we will tell you that up front.
Is the calculator estimate my final price?
Why do you need to come to my house?
Why do you ask for everyone involved to be at the consultation?
Many companies ask for every decision-maker to be there so they can push for a signature that same night. That’s not why we ask.
We want everyone there because we’re designing something for your home, and the best results come from hearing from everyone who will live with it. It’s also hard to pass along everything we talked about once we leave.
Your quote is good for 7 days, so you’ll still have time to talk it over and decide on your own schedule.
Do I have to replace all my windows at once?
Do you run "today only" deals or high-pressure sales?
No. Your price is your price. We give you space to make the right decision for your home without a rushed offer.
