"My interaction with this company, represented by Gordon Rudd, was limited to a site visit only. Work that I thought might be needed turned out to be unnecessary. When I called the company, I reached Gordon directly, and he was able to stop by the next morning, right at the time we scheduled. He was very helpful in explaining what I was seeing. He didn't charge me anything for the very helpful visit."

Since its inception by co founders William Barr and Michael Strmac in 2002, Universal Windows Direct has lived by the philosophy of CANEI - "Constant and Never Ending Improvement". This philosophy holds true in all aspects of our business, from sales and marketing to installation and service and has catapulted UWD from a small, local home improvement company to one of the largest exterior remodeling companies in the country. Every one of our employees strives continuously to be the best in the business at what they do and provide our customers with only the highest levels of sales, service, and support. We think our company's history speaks to this goal and to the power of what we can accomplish by never settling. Universal Windows Direct of Milwaukee opened in 2020. Our products feature the exclusive UniShield brand and come with a transferable lifetime warranty on materials and labor. We are a fully licensed, bonded, and insured company and EPA Lead-Safe certified. In addition, a portion of every sale goes to support a growing list of local charities.

Arx Innovations, LLC is currently a sole proprietor, multi-faceted business. Typically I bid smaller projects and am able to provide a high level of quality while saving my customers in some cases, substantial amounts of money. Even though my forte is masonry related applications, I have a significant amount of experience in other applications as well. I will not bid on a project if I believe I cannot provide the highest level of quality and professionalism. If there is a larger project that you would like me to place a bid on, I would also be willing to hire employees on a temporary basis for your project needs. For new customers, I typically require a down payment of 50% on the day of the jobs commencement. Please contact Arx Innovations, LLC and I would be glad to show you options which may save you money. Also, since this is my first year as an LLC, I would like to offer a $50 good will referral fee from any job over $500 labor cost after final payment is received.

Insulation questions, answered by experts

You should insulate ducts in a crawl space if you live in a colder climate or you run your air conditioning for most of the year. Insulating ducts doesn't take too much time or investment and can make a big difference on your electricity bill. While this is more difficult in a crawl space, if any ductwork is being done either you or a professional will be down there anyway. A bonus benefit is since they will be putting off less hot or cold air they'll be less attractive to any unwanted pests in the home.

The benefits of insulating your pipes include preventing freezing, sweating, and condensation. In addition, insulating your pipes can make your home more energy-efficient by keeping your pipes from losing or gaining heat. You’ll be able to turn the temperature of your water heater down by two to four degrees Fahrenheit. According to the U.S. Department of Energy, this can reduce energy costs by 3% to 4% per year.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

Yes, you should insulate your PEX pipes if you’re wondering how to keep water pipes from freezing. Pipes in uninsulated rooms or outside the house should always be insulated. If you’re looking to save money, you may not always need to install insulation on PEX pipes that are running through interior walls with insulation.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.
