"I had infinity do insulation and an attic blanket for me back at the beginning of winter. I waited to post a review so I could see if it helped keep the house warmer. And it did, I no longer have to bundle up in my home. Outstanding service, I am impressed. I will continue to tell my friends how pleased I am with the work. And the next time i need a project done, I will call infinity without hesitation"

"Dave and his brother, Allen, were very personable and explained what was wrong in our attic and what they planned to do about it. I hired an electrician to replace all of the antiquated fire hazard nob and tube wiring with up to code wiring. Then I hired a roofer to open up our closed ridge vents. Then Allen and Ben sprayed 12 inches of cellulose insulation into our attic. The men cleaned up after themselves, and made certain that we (the new owner and myself, the seller of the house) were pleased with the result. I recommend Mulder Insulation highly and with absolutely no reservation whatsoever."

"Greg, the owner, came out on two occasions to discuss the crawl space and drain tile. He is extremely knowledgeable and experienced in the crawl space industry. We had a few options and he told me about the new spray product he was using. It is this unique seamless liner that is sprayed on after preparing and insulating the area.
His crew was very professional and easy to talk to. We had some scheduling conflicts that were easy to work around and get the job done when we needed it to be finished.
The difference we noticed in the smell in our basement, the effect the insulation and seamless lining had on the air conditioning in our family room (which is above the crawl space) was immediate. We feel cooler air coming through the duct work since it isn't losing energy traveling through a non insulated space anymore and they basement smells and feels normal since the dirt and concrete is now completely covered by the new liner.
That new product is great.
Greg's company also did drain tile work in our basement. It was a different crew than the group who did the crawl space, but they were equally as professional and easy to work with. Rather than break up the job into 3-4 days they stayed late the first day to get everything ready and prepared so they could complete the job quicker. The job was done the next day. The price was very fair and the crew was extremely clean throughout thew whole process.
We now have a water tight, well insulated basement and we couldn't be happier with the results.
I have told several friends about the experience and would recommend them anytime. From Greg down to each of his crew members they really know how to do a good job and work with the customer."

"I own a 13 year old home, and my roof issues began in Fall 2019 when I began to notice several leaks. I began to call local roofers, and had several come out, the leaks were repaired, but all of them suggested that my roof needed to be replaced and was nearing it’s useful life. When Spring 2020 rolled around, I began to search for a company that could replace my roof. While conducting my research, a friend referred me to a local home inspector to obtain his opinion on my roof (replace vs additional repairs). This inspector suggested I contact Dennison Exterior Solutions as they had a great reputation in the area, and he personally had good things to say about them. At about the same time, I began to research my options for a warranty claim on my shingles as they had been shedding granules since I moved into the house. When I began to look around on the Certainteed web site, I noticed that Dennison was listed as the top contractor in my area, so that reassured me I was on the right track. Early one morning, I called the office number for Dennison and left a voicemail message. At the end of the message, it provided an email address to contact Scott Dennison (Owner). I left a voicemail message and immediately sent an email to Scott. Literally within minutes of me sending Scott the email, I received a response from him. We exchanged a few emails and he advised that he would have his office contact me to schedule a visit/inspection. Later that day, Amy contacted me to arrange a visit. The initial visit was set up and as the appointment approached, I received a phone text message reminding me of the visit and asking me to acknowledge the appointment. These are the reasons YOU should select Dennison Exterior Solutions to replace your roof: 1 - All presale visits were on time and took place as planned - not rushed, thorough Dennison was one of the few roofing companies that actually went into my attic for an inspection, and provided a thorough solution to my problem 2 - As part of the estimate preparation, a drone was used to take high definition photos of my roof, these photos were used during the sales presentation 3 - Throughout the entire process, I was able to communicate with Scott Dennison via email, his responses were close to immediate 4 - As part of the contractor selection process, I asked Scott for references of customers who had their roof replaced as well as active roof replacement jobs. We called all of the references, and visited several active jobs. All references advised us that once they met with Scott to review his estimate, they proceeded with the work 5 - There is no viable comparison when it comes to cost estimates. Scott’s presentation was very detailed, specific and thorough. During the sales presentation, he had samples of the vents and products he was planning on using on our project. Again, solving our problem 6 - Scott advised us that the reason our shingles have failed was due to poor ventilation and possibly poor insulation. All rooms in our home have cathedral ceilings which are not accessible via the attic. Scott ensured that his team would remove roof sheathing in each section of the roof to inspect the ventilation and insulation. Problem SOLVED 7 - Every detail that Scott went over with us during the sales presentation ACTUALLY took place when the roof work was being done. The sales packet included exhibits that illustrated how the drip edge would be installed as an example 8 - We decided to award the work to Dennison Exterior Solutions at the end of Scott’s sales presentation. We were blown away by the level of detail, knowledge and experience. Scott even took the time to review possible additional costs items that were not part of the estimate (replacement of damaged wood sheathing, insulation, etc) 9 - At the end of the sales presentation, Scott told us that it would be between 4-8 weeks before the work on our roof would begin, but told us he would share a web page with us where we could monitor the “ranking” of when our job would start 10 - About a week after signing with Scott, we received an email alerting us that the work may start sooner than he anticipated. Sure enough, the work started within about 10 days of signing the contract. EVERYTHING that Scott told us would happen actually happened: A - The supplies were delivered on time B - The crew showed up on time everyday C - The crew cleaned up my yard and protected my shrubs - there was no damage to my property D - The crew followed the detailed installation instructions of ice and water shield, drip edge, shingles, ridge and vent caps as detailed in the sales presentation - this solved my problem The crew removed one sheet of roof sheathing in every section of my roof to inspect the ventilation and insulation. Lucky for me, the builder had done both properly E - The crew replaced rotten wood as needed and allowed me to inspect the damaged wood F - The crew took pictures of all of the work they completed - before and after G - The crew answered all of my questions and were friendly and professional H - The crew met with me each day to review the work ahead for that day I - Scott was the only roofing company that submitted a thorough solution to address the root cause of my problem. SAVE YOURSELF TIME, GO WITH DENNISON, YOU WILL NOT BE DISAPPOINTED! Feel free to contact me if you have any questions or concerns. Sincerely, Donovan Cartwright"

"he originally called Jake Evink, of Roofs and More about some holes in our roof because of the wind storm last year. When he came to give an estimate, he also took the time to put tape over the holes so that the roof would not leak anymore until it was repaired! Unfortunately we had promised the job to another provider before Jake came.
When we decided to have insulation added to our attic, Jake's estimate was @$75 dollars higher than the lowest estimate but we chose him for two reasons: his previous considerateness regarding our roof and his suggestion that he could run the hose into the attic thru the gable vent instead of thru the front door.. Jake also thoroughly explained what needed to be done and how he would do it.
After several delays due to bad weather and a death in our family, Jake came with one other worker and blew in the insulation. When he was done, He encouraged me to go up the ladder and inspect his work. He and his assistant were friendly and were careful regarding our rugs and furnishings. When they were done, they cleaned up thorougly. Our house already feels warmer!
PS - Jake subsequently followed up with information so that we could apply for a tax deduction and a rebate from Consumer's Power.
