"It went very well. They obtained the materials and scheduled installation about two weeks sooner than expected, which was great. The installer worked diligently along with a plumber, and the job took one day plus a few hours. I'm very satisfied with the results."

Kulp's of Stratford is a full-service roofing, insulation, windows, and solar PV contractor, with 42 employees, and a track record of 25 years of quality work and customer satisfaction. In residential roofing, we offer the best asphalt shingle warranty in the industry by virtue of our GAF Master Elite status, one of only three in central Wisconsin, as of spring 2016. We have more experience with stone-coated steel and standing seam steel roofing than any other contractor in the area, with hundreds of jobs to show for it. Our customers are often those who see their home as their "castle", and who are committed to it for the longer term. We only use subcontractors in rare instances, and only when our clients understand and agree to the reasons for it. Our crews have received training for installing asphalt shingle roofing, spray foam insulation, copper roofing, replacement windows, asbestos roofing abatement and removal, OSHA 10-hour courses for construction, aerial lift and forklift training, and frequent safety training. Our safety record has been nearly perfect for three years, and we are fully insured with worker's compensation, general liability, and auto policies, with a $5,000,000 umbrella policy. Some our specialties are: Properly insulating cathedral or vaulted ceilings in conjunction with re-roofing, where ice damming, condensation, and heat loss have been issues; performing complex and large metal, tile, and shingle projects that many contractors avoid. However, we do many basic and less complex projects as well, with the same attention to detail as the larger ones receive. Browse our website, www.kulproof.com, where you will find much more information and lots of photos of all types of projects completed over the last 10 years. Then pick up the phone and give us a call!.

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!"

Insulation questions, answered by experts

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

While adding insulation can be beneficial, there is too much of a good thing. Too much insulation can seal your house to the point where it can't release moisture that enters it—essentially trapping water vapor inside. Warm, humid climates are extra susceptible to mold from moisture issues, but homes in colder climates can experience condensation from an air-tight home when freezing temperatures thaw.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
