We were v, ery pleased with the insulation work, price, communication, and friendliness. We are new in the area and did not know who to contact a first for insulation services. We had just purchased a used 1995 manufactured home with a "cathedral ceiling" that had very poor 3" ceiling/roof blown-in cellulose insulation (but lots more open space available between ceiling and roof sheathing for more ) and no way to access the vacant space above the ceiling without tearing out huge sections of ceiling drywall (for foam insulation), or drilling a lot of holes (for blown-in) or tearing off the roof. None of which were good options for us. Denny came over and said he could actually get in through the soffits at the roof edge, all the way around the house, and with his long hose extension feed the insulation blower hose all the way up to the roof ridge and fill up each cavity by drawing the hose backwards as it expelled the insulation, from the peak down to the soffits. Which he actually did. I could hardly believe it. A very creative solution for a house not built with good insulation in mind or any thought of retrofitting/access. The positive difference in house warmth and furnace/propane usage was immediate. And the price was very fair, about 1/5 the price being quoted by other companies (for spray foam), or others who just shrugged and said "no way." Denny and crew also properly vented each cavity in the process, replaced dozens of soffit screens, and the crew cleaned up perfectly afterwards. They did the whole job on time, in just a few hours, and Denny actually charged less than the original quote because he was unable to fully access a few of the many ceiling bays due to cross-beams he discovered once the project was underway. I would never have known this (that they had to skip a few bays) and he could have charged the original price anyways. So I was impressed with the honesty and integrity. The D&N crew was a friendly, hard-working group who stopped to answer all my questions and seemed to actually enjoy their jobs. We were so impressed we had D&N come back a month later and insulate our crawl space (all block walls and rim joints) with spray foam insulation. Again, great work, on time (actually a day early!), friendly service. Now we're going to get them back a third time (!) to insulate underneath the floor of a guest cabin on our property with spray foam. We highly recommend D&N Insulation for anyone seeking fast, fair, honest, professional service at good prices. And they'll actually return your call. Jeff and Regina Cassopolis, MI Feb. 2022

Very pleasant young men who were very professional. They did a great job and also cleaned the area they went through to get to the attic. Would definitely recommend them.

Dennis and his guys were on time and professional. If they made any kind of mess I didn't see it after they left. Would definitely recommend them.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
