"Andrew was very knowledgeable, efficient, clean, affordable and helpful. He explained everything to me as he worked on the projects I hired him for. He also took extra time to look into other issues I was having that needed parts ordered. He priced them for me and let me know he could come back to install. I will have him come back and would refer him to friends & family."

"I called my fuel company to schedule an annual furnace tune up and was asked if my chimney was cleaned recently. It wasn't so Petro highly recommended calling Guaranteed Home Improvement. I did and spoke with Mark who made an appointment for a service call. Justin arrived promptly and did a thorough inspection of the exterior and interior of the chimney. He provided photos that were helpful as he described the damage in the flue and cautioned about the possibility of carbon monoxide building up inside the chimney. He was very knowledgeable, clear and concise as he explained that inserting a liner would divert smoke and heat from corroding the clay tiles filtering into the house. The photos of missing and disintegrated tiles at the base of the flue were enough proof for me. Justin answered my questions about the work, when it could be done, how long it would take, the cost, etc. The decision to go forward was a no brainer for me and as I was comfortable with Justin's responses and he arranged for a crew to come over within the hour. Charles and Taj arrived soon after and immediately began installing the liner in the chimney. They were professional, courteous, worked well together, and completed the work in a short period of time. Eric contacted me later to find out if everything was okay and I said I was completely satisfied. The entire process from the initial call through the follow up conversation from Eric was handled very well. In fact, everyone I interacted with at Guaranteed Home Improvement was friendly, professional, and fine examples of good customer service. The unsung heroes were the receptionists who redirected my calls. I am very thankful for the fine repair work and the peace of mind that came with it. I enthusiastically recommend anyone in need of their services to give them a call. Marvin"

"This was our second time working with Clear River Environmental. They installed our new septic tank and leaching pool over a year ago for $7200. I was hesitant to use them again due to their lack of communication with regards to follow-up documents which were required by the Health Department. They attributed their lack of sending me the "as-builts" and other required certifications to having switched over their computers to a new system. Nevertheless, the issue was eventually resolved after numerous calls to their office. Fast forward to 11/19/20....I called them to install a future expansion pool which was required by the Health Department. I figured that they were at least familiar with the property and I had no complaints with the actual install from last time. Long story short...they cut through a gas line to our pool which necessitated a call to National Grid. They also destroyed large branches from a tree, a large portion of recently installed sod, as well as pavers and the curb cutout. Granted all of this damage is listed on their disclaimer, however I was a bit dismayed when they refused to compensate me for any of the bill that was required to do repair work. I understand that the owner is responsible for informing the seller of "underground perils," however I would also expect the professionals to ask the right questions before beginning a job. I would also expect professionals to consider something more than just the "repeat customer" discount to alleviate the buyer from some of the expense and stress caused by the damage of the gas line. This second job cost $5,300. Total money paid to Clear River Environmental = $12,500 . The repair to gas line cost me $900 . The pavers and curb have yet to be repaired."
