A: Condensation forms when there is excess humidity in your home and while it is unsightly, it is also generally harmless. The water vapor will condense on the coldest parts of the home (glass in the windows, bathroom mirrors). Additionally, the old drafty windows have been replaced, making your home a "tighter" more energy efficient home.

I have heard horror stories about roofers taking advantage of people so, as a single woman, when experienced extensive hail damage and had to get my roof replaced, I was concerned about finding a company with integrity that could walk me through the process. Fortunately, a colleague at work recommended National Home Improvement. He explained that they would partner with me throughout the entire process, ensure fair costs, quality materials and work, and would even help me understand every step of the insurance process and help m get the max value possible with my policy.

This all sounded too good to be true, but everything my colleague said was absolutely right! The owner of the company, Steve, personally came out to meet me and gave me an overview of the entire process and took the time to answer all my questions. Steve and his team took care of everything from submitting estimates and photos to my insurance, to securing permits and materials, to scheduling the team and work, to getting the final inspection and sign off.

Every step happened exactly as Steve had explained - the whole process was literally effortless! I had a vacation planned and Steve even kept things moving for me while I was out of the country! The quality of the work was great and the crew did a good job cleaning up debris. A couple minor glitches (some debris fell inside my garage and the crew couldn't get to it, the gutter down spout was dented accidentally) and Steve went above and beyond to replace/resolve- I was so impressed!

As a single woman, I can't express what a relief it was to find a partner with integrity that I could trust to walk me through the entire roof replacement process- I would recommend Steve and National Home Improvement without reservation and will definitely use them again, should a need arise. Thank you Steve and team!

I can't say enough good things about this company. They did 3 significant window replacements in our mid-century house. Communication, price, timeline, and work quality were all 5 out of 5. Love this company and will try to hire them again for our exterior refresh. Service: Window installation

Salesman helped me get more money from insurance company. Workers completed roof in one day (small house) with no mess afterwards. Gutter guys came at 6 am. I slept in and they had completed it by 9 am when I got up. They were quiet! Great service and comparable price. Service: Roof installation

I'm really a tough customer and if it isn't done to my satisfaction, it will be. Steve took everything in stride and made sure my roof was done with excellence, my house was painted like Picasso, and my deck roof was done to perfection. Oh, and he got the insurance company to replace my air conditioner because of all the hail damage. Nope, he probably doesn't want any more customers like me, but I believe in doing a job with excellence and being responsible for the work. That's accountability and NHI has it.

We contracted with Nat'l Home Improvement to handle several improvements/repairs. Steve Becker came to our home and did a very thorough inspection. He guided us through making the best chooses for our improvements/repairs, how the insurance process worked and helped us get the best possible price for the items insurance didn't cover. Nat'l Home Improvement worked directly with our insurance company regarding hail damage related improvements and directly with us regarding general maintenance improvements. Steve and his staff were very professional. Nat'l Home Improvement didn't have any hidden fees and stuck to their quoted price. We were extremely satisfied when the job was done. We would recommend Nat'l Home Improvements.

National Home Improvement replaced the windows in our home several years ago. When we decided to put up vinyl siding rather than painting our house again, they were one of our first choices. At each step along the way, NHI had patience with endless questions (some of them probably stupid-but I knew nothing about siding before we started) and my challenging schedule (I work out of town nearly every week).

When Steve came out to measure so that he could order materials, he found hail damage on our roof that required that a roof replacement be added to the work. NHI worked directly with our insurance on the roof replacement, leaving us free to ask about a billion MORE questions. The schedule for the roofing was difficult as the rainy spring kept delaying the planned start.

But once they were able to start, the job went smoothly and quickly. And then we moved on to the siding, which also went very well. There was a miscommunication (on my part) about the size of one of the shutters, and it had to be reordered and installed. Despite the fact that it was my fault, they managed to come out and fix the issue within a week.

I also have to mention that Joyce and Christy in the office are great. It is nice to be able to reach out and have someone in the office to answer questions rather than having to try to catch the contractor between sales calls and jobs. Our house looks great now! I highly recommend NHI for your window, siding, roofing and gutters. We couldn't be more pleased with the job they have done on our house.

NHI was our contractor for our extensive hail damage. They worked with our insurance to get the most money possible to cover the cost of a new roof, new bay window, gutters, and vinyl siding. Steve, the owner, was great to work with. His workers did a fabulous job both in quality and timeliness. I give this company my highest recommendation.

I have used National Home Improvement, Inc., since the late 90's for window replacement, siding, gutters, and roofing on 3 different residences. Steve Becker of National Home Improvement is the most honest and open person I have ever had the pleasure to deal with. Steve gives more than 100% and actually cares about his customers! Joyce in the office is very knowledgeable and helpful even during National's busy times of the year.

If she does not know the answer to a question she will get back to you with an answer! I highly recommend this company for your home improvement projects. You will get a competitive price and quality craftsmanship from this contractor.

I have used National Home Improvement on four (4) separate occasions. Two jobs were insurance claims and the other two jobs were for home improvements. NHI handled the insurance claims totally and did a superb job. The claims dealt with roofing, siding, gutters, windows, and doors. The other two jobs were for roofing and gutters on a second home. All the work was done in a very professional manor and on time. NHI is great with communicating and setting reasonable schedules for the work. Steve Becker is the owner and Joyce is his office staff.

I will continue to use NHI for all future home improvement jobs. I have also referred NHI to friends and neighbors who have also used their services. I highly recommend them for insurance claims related to storms/hail damage. You won't be disappointed.
