We contracted Reitzel to remove existing insulation and install foam our attic and upper story, and are super pleased with the result. Our job required extra coordination between Reitzel and our roofer (Platinum, also recommended), because some of the foam needed to be sprayed on exposed ceiling when the roof decking was lifted while replacing the plywood and shingles (see photos). Reitzel handled the job with professionalism and attention to detail, and everyone from estimator Bryan, Manager Jamie, and installer Jeff was helpful to see that things went smoothly. They cleaned up well and protected our things, and the foam smell was gone within 24hrs. We're already feeling the difference the foam has made in our upstairs and look forward to easier temperature maintenance and efficiency throughout the summer and winter months. Excellent work!
