Summit Insulation's Spray Foam Insulation I'm the original owner of my Ryland home Crofton, which was built during fall of 1992 and completed January 1993. I was the first home owner on Patrice Circle in my Crofton Woods neighborhood. I have the McHenry model, with a Victorian style facade. Grey Aluminum siding, with navy blue shutters and door, and white trim. Over the years, the traffic and noise volume has only increased on Rt 3/301. Although up to code insulation wise when built, and with replacement windows and new exterior doors already installed, I still could not escape the growing traffic and neighborhood noise. My MHIC Geremias Gomez had jokingly said to me - "Welcome to the mobile home park". I burst out laughing and replied, you're absolutely right! I then began the search to find an insulation contractor who would spray in expanding foam insulation to fill the space between the exterior siding and the interior sheet rock walls. Baltimore based Summit is the only remaining company that provides this type of insulation service. So I contacted them, and Tom Ragsdale came out, gave me the estimate and I quickly signed the contract. The work was performed yesterday, and all day event from 7:30 am to 5:30 pm. Chris and his all Latino team of seven men were wonderful to work with. Very respectful of me and the interior of my house. The exterior of my house, grey aluminum siding, now looks cleaner and brighter than it did before they began their spray foam insulation process. I can already tell the difference in noise reduction, and it's been less than 24 hours since they finished their job! Finally I'm very grateful for the caring manner with which my Latino crew treated me. They knew I had my right hip replacement surgery less than 30 days ago. They were so careful to make sure I didn't accidentally stumble and fall, extending me an arm to grab if needed. In short, they treated me as they would want their Abuela to be treated. Muchas gracias mi Amigos! Melanie Smith
Just had my entire house insulated. It's a 25 year old house, but we would get drafts, and our electric bills were sky high. Had an OUTSTANDING experience with everyone from Joe the estimator, to Chris the crew supervisor, as well as Dan the owner. Everyone was courteous, professional, and extremely hard working. My house was a 2 day job, and it rained on the first day, but apparently that doesn't stop these guys at all! The entire 4 man crew kept working through the rain, and came back the next day to complete the job in it's entirety. I was able to see and hear the insulation being pumped into my walls, and it's still only the first day since the completion, but the sound difference is immediate. I already live in a quiet neighborhood, but now you can hear a pin drop. I didn't even know that sound reduction was a benefit, but if that's what you're looking for, this stuff really works! Time will tell if my heating and air conditioning bills improve, but I can say that I already feel cozier as the weather is finally turning cold. I highly recommend Summit insulation, and taking the time to compose this review is proof enough, as I rarely write reviews at all :)

I've been a homeowner for 21 years. In all that time, I have used dozens of contractors for renovation, HVAC, roofing, electrical, plumbing, etc. I can now add Dan Smallenbroek as only the third contractor/consultant that I trust implicitly to that list. Prior to working with Dan, I received an estimate from another highly regarded insulation company for attic encapsulation. In fact, that company's name was the only one I had heard from anyone I asked about potential insulation companies. The salesman was knowledgeable, but had a one size fits all approach. This other guy didn't try to understand what I was trying to accomplish and just kept telling me that trying anything else would not work. I called Accurate Insulation to get a second estimate to see if it jived with the competitor's. I explained to Dan that I thought I already had a good company with a reasonable quote but wanted to make sure I was getting what I really wanted. Dan promised to come out, survey my attic, and give an honest recommendation. With his help and collaboration, I picked a system that worked for finishing an attic. He spent a significant amount of time educating me about R values, the difference between blown in, fiberglass, open and closed cell insulation, and the rebates and tax credits for which I was potentially eligible. He was never pushy and not for a second did I feel that he was trying to upsell. The energy audit ended up getting me a 35% rebate which Dan facilitated on the front side. He also gave me the resources to help me apply for a federal tax credit which means the final cost for the entire insulation project will be a whopping 50% off Accurate's quoted price. This doesn't mean others will have the same result, but it's nice learning ahead of time what your all-in cost will be instead after the fact when you're not eligible anymore. The energy audit process means that everything takes more time, but it also means you'll probably make a better informed decision at a fraction of what a job actually costs. It's 91 degrees oustide right now. My HVAC unit currently sits in conditioned air space at 74 instead of 130 degrees and we're in the process of having the attic finished off as an office for my wife. I'd be remiss in not saying Accurate's energy auditor, Mike Sears, spent an extra 90 minutes post-audit going over problem areas in my house and offering his own insights for improving energy efficiency. The encapsulation reduced air flow loss by 31% which has to translate to lower heating and cooling costs going forward. If you're considering insulating your attic, I can not recommend Dan Smallenbroek and his crew with Accurate Insulation highly enough. Much obliged - Kevin & Diann
