"Harry quickly got back to us to schedule a time to come out to give an estimate. We needed the work done quickly so that we could get new windows installed. Harry came back with a reasonable quote. He was a little late on the start window but as soon as he got there, he got right to work. He was able to complete the work in about 5 hours and only one small trip to Home Depot in between. He was knowledgeable and made sure we were satisfied with the job before he cleaned up."

"We purchased 37 replacement windows. Paul, the owner, was very personable and informative. No pressure was ever applied to purchase. On installation day, the workers showed on time, were polite, and were very efficient. They replaced all 37 windows in 1 day working until dark and returned the next day to finish the flashing around 10 windows. Paul showed midday on install day to see how things were going. We have hired IHI to replace a door and fix some flashing on other areas of our house. I highly recommend IHI."

"The work that Bobby did was rebuilding a shed ramp, installing new porch screen door and repairing large window ledge. All I can say is that he made everything better than new! Couldn’t ask any anyone more professional!"
