As one ages and cannot continue to do needed improvements to ones' adult lifetime home, it was comforting to deal with an honest and trustworthy individual like John Jones from Guardian. He was thorough, thought worthy, and straight forward with answers to my questions. He was both 'in service' and 'of service' to both my wife and me as we contracted for aluminium facia, rain gutter replacement., and other minor repairs.
He was informative and availed options in a very professional manner. His intent was not to (up sell), but, to provide information so we could make an informed decision. Thank you, and we are looking forward to the project completion.

We had a hail storm in our area that caused significant damage to many properties. When I called in Guardian to help, I was very pleased with the professionalism and personable representative from the company. The insurance inspection was quickly expedited and the project was soon to be organized. Throughout the process from initial contracts, scheduling and work completion, I was very pleased with the effort and efficiency of the staff both here and at their office. Their online portal was state of the art for payments, etc. Top notch all around. Most of all the workers worked very hard and efficiently and paid attention to the safety of our property and quality of the work. Thanks Guardian!

My adventure with Guardian began in December, when I returned from a month abroad to learn my homeowners insurance policy was in danger of being cancelled due to the age and condition of the roof. I met with 9 companies over the course of a week; Marcus from Guardian was the first rep I met with and his friendly, personable nature coupled with the thoroughness of his inspection earned my business. He got up in the attic and onto the roof to take photos and explain the needed work. Guardian's bid was the second highest out of the 9 but I felt tremendous confidence moving forward with them based on my conversations with Marcus.
Kaila from the business office was instrumental in coordinating and was a pleasure to work with. Install day got pushed by 48 hrs due to a weather delay (not unreasonable during a WI winter) and she made sure the new date worked with my schedule. Josh Moore was the Project Manager and also a great communicator. The crew put on a row of shingles that was crooked, and he made sure they came back to fix it that Saturday.
There was a preexisting leak at the back of my home where water got down and rotted out part of the soffit and framing around a window. I asked for a quote for that work but something got lost in translation and it turned into a whole situation wherein I was quoted a price for the work I requested that, apparently, was intended to be what it would cost if I agreed to side my entire home. I am grateful to report that, once I expressed my frustration with the communication breakdown, Joe from Guardian reached out and we were able to negotiate a contract that addressed the area in question. This work was completed relatively quickly and to the letter of the contract under Josh's supervision. The workers were very respectful of my home when they needed to access the interior and cleaned up thoroughly.
I removed one star from my rating to reflect the issues that arose but I feel confident recommending Guardian based on my overall experience.

Cody did a great job filling us in about Solar Energy. I learned a lot and will definitely consider solar in the years to come. I need to upgrade a few other things in the home to make it more energy efficient before we can add the solar panels.

Cody put alot of effort into my options and explained my choices. He was open to discussing my options and has a true understanding of his customers. A very honest caring person.

Marcus came out for an 11:00 appointment and was on time and very professional and personable. He gave me cost saving suggestions when he didn't have to. To be honest I was already set to go with another company and just wanted a 2nd quote, but because of the customer service I received I went with Guardian and signed the contract that same day. Marcus left my home 2 1/2 hours later and I felt like he was a part of the family because of the great conversation we shared during his visit. Thank you and I look forward to seeing the completion of my house.

Working with John Jones was a great experience. He helped me understand my siding project better than any of the other companies I had out to give me a quote. He's the only one who took the time to inspect the roof and explain how the siding, roof, and ventilation work together.

Guardian was great to work with. Joe and Josh were present to answer all of our questions during the installation of our new roof and gutters. We had a particularly difficult issue with water flow around our chimney that they corrected with a great deal of thought and personal attention. They arrived in the time frame they stated in the contract and their crew were friendly, respectful and professional. We recommend them.

I would rate Guardian a 4.0 to 4.5.
The salesman, Patrick was quite good. He provided a detailed quotation and did everything he could to get my business. He made a very good first impression! The front office was not responsive after they received my down payment, but once I called around and became persistent, I was assigned to a different representative, Patty H. Patty apologized and followed-up to ensure my project was scheduled before the date listed in the contract.
Art and his crew did a very good job, worked around the rain and even stayed late to get the roof and gutters done. His crew had good attitudes and did quality work. They did a good job cleaning up afterwards.
Josh and Mike (project managers) also stepped in to ensure my siding repairs were done according to my instructions. When one crew member damaged one of our bushes, and another one left rather large ruts in my front yard, they made sure the turf was repaired and that I was compensated for the damaged bush.
Patty H. kept in touch throughout the project.
I do hope that Guardian is able to resolve their issues in the office. If I was not as persistent, this may not have turned out as well as it did, but I give them credit for ensuring that I was satisfied. Job well done!

Guardian Home Improvements was a great company to work with from start to finish. They are reliable and very prompt. The installers went right to work and were very conscious about keeping the area clean of any debris. The roof looks great and much thanks to Joshua Moore the project manager!! He was a pleasure to work with and explained the process so there were no surprises. He complimented the install team by sharing how they have great workmanship and how well they clean up after completion. I will recommend this company in the future and will call them for any other improvements we may need!
