"We had four windows replaced with lead mitigation procedures.  They did an excellent job and nearly got the job done in one day and only had to come back a second day to finish up a bit of caulking.

"Mike Miner was my sales rep, he was amazing and so down to earth. My installation guy was Emilio, he was thorough, quick, energetic, friendly and put all 9 of my windows in on his own. Took about 9 hours. Great clean up and great customer service and communication from the office! I get so many compliments on my windows from neighbors!"

"Bill Millis did an excellent job removing our original windows and installing new Pella windows. He also worked hard to allow us to keep our existing aluminum siding, which was no longer available. I have provided his contact information to several neighbors and friends."

Windows FAQs, answered by experts

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.
