With over 10 years in construction, one thing is clear - anyone promising a “stress-free, perfect project” is selling you something.\nConstruction is complex. There are always variables. \nWhat we do differently is set clear, realistic expectations from day one.\nWe focus on strong communication and high-level craftsmanship. If you want honesty, accountability, and a job done right, you’re in the right place.\nWE DO NOT WORK WITH INSURANCE CLAIMS

"Chris is a hard worker who does quality work. He worked through the Holiday weekend. He replaced all the windows the first day and came back the next day to finish all the trim work. They were vinyl replacements for old aluminum windows. This is the second time we hired him. He replaced two large sliding glass doors for us 5 years ago, so not only would I hire him again but I did hire him again. We received 2 other quotes and Chris came in the lowest by far. He's basically a one man show which I think allows him to keep his overhead low and the savings is passed on to the customer. He uses Milgard windows and they look and work great. We looked at other products and the Milgard looked to be as good as any other. No regrets."

"Nir came out to the house to give an estimate. He is extremely professional and informative. He gave me some wonderful ideas on how to move forward with reconfiguring my kitchen and possibly adding a family room. He was extremely knowledgable and innovative and a very kind person. I would definitely recommend a meeting with him on any projects you are considering."

"I am very satisfied with the work that Tony did for me. Very efficient and high quality job with a fair price. What really set Tony apart is I had to leave town before the job started for a family emergency, and he was able to complete the job without me being there, staying in communication with me every step of the way. This proved to me that he is trustworthy and accommodating on top of being great at his work. I would highly recommend Tony and Nexxus Remodeling to anybody"

Egress Windows questions, answered by experts

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

The primary benefits of an egress window include providing a safe emergency exit, increasing natural light in a space like a basement, and improving ventilation. Additionally, installing an egress window can often increase your property's value.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.
