"Mike was wonderful. He came out to quote the work and did it in the same trip. He made sure everything worked and put all my patio furniture back when he left. I now have a fully functional patio door and Iâ m ready for summer, or at least spring. THANK YOU Mike and Angie!!!!"

"Renewal by Andersen provided an excellent experience from consultation through installation. The entire process was professional, organized, and far less stressful than I anticipated. The team communicated clearly throughout every step, arrived on time, and completed the installation efficiently while keeping everything clean and orderly. The quality of the windows is outstanding, and the difference in appearance, comfort, and overall feel of the home was immediately noticeable. I especially appreciated how thoroughly everything was explained, including the installation process and maintenance tips after completion. A special thank you to the consultant for being knowledgeable, patient, and professional during the consultation process. There were no surprises, and the entire experience felt honest and well-managed from beginning to end. I would highly recommend Renewal by Andersen to anyone considering window replacement."

"In addition to the installation of a light, they also installed a medicine cabinet. Both needed some additional work- installation of a junction box and hole needed in a plastered wall; filling in of extra space around medicine cabinet rough opening. They also replaced some wood trim around a large tool shed. Job came out great. They were professional and conscientious to take care within my home. Tom and Mike did a very nice job."

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

"This pair of true craftsmen worked magic on my old but serviceable 28-year-old wood windows. Two casement & two large fixed windows suffered substantial cosmetic rot in sash, sill &/or brick-mold. Windows were removed & completely rebuilt. The skill displayed in fashioning the intricate re-framing of the windows from 4â x4â stock using a table saw amazed me. They did additional exterior work, replacing rotted wood trim around the garage & chimney areas. All work was caulked, & repainted. Half dozen other contractors shied away from any cosmetic repair, each suggesting full window replacement. Work was done very reasonably compared to replacement cost, they look brand new. I thank God they came to DeKalb for us & saved our beautiful windows. Prayers answered, they have our highest recommendation."

"Tom was extremely professional, careful, fast, and timely in his work. He responded promptly to my request for an estimate. Provided a great solution to the problem I was having. And was able to get the work done in a tight time frame. His price was very reasonable. He went above and beyond to improve the flashing before installing the new siding."

Gutter Repair, Gutter Cleaning, Handyman
"Rob was great!! I needed our HOA gutters cleaned out before the snow buried the fall leaves a 3rd time. He showed up when he said he would and provided us a quote and we hired him immediately. He started work a couple of days later and over the course of two days he removed and bagged all the leaves that were clogging our gutters. We have oak trees surrounding the homes so the gutters were heavily plugged. Rob came out over the course of two days, after the sun thawed out the morning frost and dug out the gutters by hand and contained everything in bags which kept the ground clean. He added a couple of hangers to one of the gutters were it was loose. He cleaned out all the gutters with a hose and ensured the downspouts were clear. I was very pleased with the service and the price. I would not hesitate to hire Rob again or recommend him. It's nice to have someone do what they say they would."

"We had a total of 7 windows plus a huge bay window replaced. The entire crew was professional, efficient and knew exactly what they were doing. They completely redid the whole framing for the bay window, including all the construction on the outside of the house. When it was completed, not only did it look like it was there the whole time, but even matched the shingles on top of the frame to match my house. They answered every question and made sure I was satisfied before they left. HIghly recommend!"

"No need to look any further for a handyman service, just hire Finished Looks you will be glad you did. These guys have 30 years experience under their tool belts and they know what they are talking about. When nobody and I mean nobody would install my drip edge extenders and my Rainhandler system they came with a smile. They also corrected other issues with my roof and replaced the cedar siding and stained it. I have no more leaks in my foyer! Job well done and I would hire this crew to do all repairs in the future. Great to work with, fair price and quality work, what more could you ask for. Oh yes, they even cleaned up the job sight."

"Alex really stands behind his work. He replaced the rollers on my patio door last year and when it recently started getting hard to close again he came right back out and made the adjustments to get it back on track. And he didn't charge me, saying that his work is guaranteed for a year. Nowadays it is getting harder and harder to find good people who do good work and stand behind it. This guy will always have my business and I will recommend him to everyone I know."
