"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

PLEASE CALL FOR QUICKEST RESPONSE TIME --Donn Anderson is a Certified Master Inspector®. He began working in construction in the mid 60’s. He started Anderson Home Inspection and performed his first professional home inspection in January of 1995. He has inspected over 12,000 homes in Southeastern Wisconsin since then. He has been a member of the American Society of Home Inspectors – Great Lakes Chapter since 1996. He served as the Education Chairman for the Milwaukee Chapter of the Wisconsin Association of Home Inspectors from 1996 – 2009. He is a member of the National Association of Certified Home Inspectors and is a Certified Master Inspector®. He received his Real Estate license in the mid 1980s. Donn was a co-author of the jurisprudence exam for licensing Wisconsin Home Inspectors. He holds licenses as a WI State UDC Building Inspector, an FHA 203k Consultant, he is certified as a Residential Measurement Provider by NEHA-NRPP to test for Radon, the second leading cause of lung cancer in the US. He works as an expert witness for homeowners who have been exposed to substandard construction and home inspection practices.

"I was in the middle of a recent home Refi to get cash out for a new roof and new windows but the credit union wanted a professional report of some interior water damage that was noted during the appraisal process. Donn, from Anderson Home Inspection, was my inspector 20 years ago when I originally purchased my duplex. I contacted Donn and explained the situation and he was very understanding of the need and urgency to get the report for the bank. We scheduled a time 2 days later. Donn quickly assessed the interior water damage and then used his very cool drone to inspect the roof. He took pictures of the roof, interior water stains, and the attic. His report was completed and I submitted it to the credit union. His determination was the interior water stains were cosmetic and not structural. They were due to the poor condition of the valley and chimney flashings and would be corrected this spring when the roof is replaced. Thanks to Anderson Home Inspection my Refi proceeded without further issues and I'm on my way to a new roof and new windows. I have many friends that have used Donn's services and never hesitate to recommend him to anyone."

Weatherization Services is experienced in using blown cellulose and spray foam insulation. We strive for perfection and enjoy generating energy savings for all of our customers. Our crews are clean and courteous and understand that “The customer is always right”. Additional phones: (414) 841-3412. Additional fax: (414) 877-1723. We use blown cellulose insulation composed of a minimum 85% recycled fibers. Unlike traditional insulation, it is not manufactured with any formaldehyde, asbestos, mineral fiber, or fiberglass. The density of blown cellulose insulation gives it a high R-value per inch, which it maintains even under extreme conditions. Cellulose insulation achieves great overall energy efficiency, because it is blown into tiny cavities. It surrounds plumbing pipes and electrical wiring, therefore reducing any air infiltration by sealing gaps where energy can escape.

"Highly recommend weatherization services ! Incredible not only did provide excellent service,but they also took the time to explain process in detail 100% recommend. "

We are a full service high performance insulation company. We also perform home performance audits that include infiltration testing and infrared imaging.

"Lee's team of insulation specialists did a phenomenal job of spray foam insulating a very, very small crawl space in our home (as well as some boxsills). We have had several construction professionals in our home recently, as we are considering a major renovation to our house, and they have all commented on how well done the job is, and how amazed they are that insulation specialists were able to access such a small space. The team arrived on time, did their work quickly, and the administrative team was very communicative, personable, and kind. We'd highly recommend Duerst to others!"

Energy Efficiency Auditing questions, answered by experts

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.
