What Our Customers Are Saying...
“I had a home sale inspection done on my home and needed a couple of repairs. I called and Dennis was able to come out the very next day because I said how important it. He was very professional and quick to evaluate the situation and had everything taken care of the same day. Incredible and very low cost. Very kind and patient. I will use them every time!!”
– Lorie Bailey
“Clear Windows did a great job for me replacing windows and balancers. Dennis, the salesman, was excellent. He saved me a lot of money by replacing only balancers when other companies wanted to replace the whole window. Their price was very reasonable and they matched my existing Anderson windows. Cliff is a real expert. After removing the old windows, they discovered rotten wood. Cliff was able to make the repair at a very reasonable cost so they could proceed with replacement. Would definitely recommend this company.”
– Donna Rau
“Dennis McHugh and his team came highly recommended to us by a friend of ours who is a home inspector. They were great to work with every step of the way-- very honest and competitively priced. The gentlemen who completed the install put the same care and attention to detail in the work as they would if they were working on their own homes.”
– Karla Lunsford
“Just had the fog and moisture repaired with new glass by Clear Window. Cliff & Law came out and did an amazing job. They also cleaned up and fixed a window for me so I could open and close it again. The pulleys had broken. I am very pleased with them both.”
– Barbara Turner
