He provided a free inspection, clearly explained what he found, and identified only minor cleaning that was needed. He also pointed out that the crown of the fireplace could benefit from resurfacing. Mace did an excellent job resurfacing the crown and walked me through the entire process from start to finish. His professionalism, attention to detail, and clear communication really stood out. As a landlord with over 20 years of experience, I've worked with many service providers, and I can confidently say CrownUp Pros is top-notch. I would absolutely use this company again and highly recommend them to anyone needing chimney or fireplace work.

May 14, 2025 I was in need of a certified chimney inspector…read moredue to the fact that my homeowners insurance (Farmer's) dropped coverage in my area in Colorado (due to fires), after many years of being covered by them. The new insurance company, found by my insurance agent, came and did an inspection, and my old wood burning cookstove, even tho not having been operated in maybe 30- 35 years, is still in perfect operating order. Andrew and Jarrod from Top Hat arrived when scheduled, performed the necessary inspection requirements in a timely and professional manner, and both possessed great 'bedside manner' (as we say about doctors) .... I received their thorough report early the next morning, along with a filled out questionnaire from the insurance company .... I forwarded their digital reports to my insurance agent, who promptly passed it on to my new insurance company that very same day. As a result, their work made my new homeowners insurance policy in play. The entire process, including communications with Andrew's wife, Emmy, was a very painless exercise that resulted in a positive outcome. I highly recommend their services to anyone in need of any type of work regarding wood burning appliances. I would use them again if needed. FIVE STARS, if not more .... Ken Rushing Drake, Colorado

Matt has been out to my house a few times now. I first used their company to clean the stack of my…read morechimney. While doing so, they sealed/repaired some issues at the top of the chimney. I'm glad they caught it, as I never would have known. The following time I had them take out my cast iron insert so we could use the full fireplace. Which they did and sealed up any cracks, along with putting a flue on the top and getting me all set. The last time he came out was to install a front to my fireplace. Every time he's been out, he's been helpful with his knowledge, offers recommendations, he's friendly. I'm not sure what average prices are for the things I've requested, (I mean how much is it to take out a cast iron fireplace?), but I'm happy with the work he's provided me with. And for just the regular cleaning of the chimney, I believe the cost to be fair. He's not just cleaning the chimney, he's also looking for potential issues. I'll have him back for regular cleanings.

When faced with the short notice preseason to find another snow removal company when our long term…read moreprovider withdrew from that portion of their business, I spent much time pursuing a replacement. Apparently many in Boulder have also given it up for small residential properties, having decided to provide only to commercial properties which is more efficient for staffing and equipment. Call after call went either unanswered or unreeled to messages to all the references I had gotten from personal contacts Even one case of someone who promised to come but was a no show. Until I found General Service on a list of licensed providers that was linked to us by the all purpose yard maintenance firm we had been using. General Services is a Boulder local family owned and managed company, now managed by the second generation. Eric, the manager was the first to respond to my request and very professionally, with a plan. They do many other services too so if I need to add other options as needed, I can. There are many ways to customize the snow removal plan. If a customer needs complete coverage for any drop it can be done but we were able to customize to the trigger depth, in our case, 3" to avoid charges for snowfalls we can handle our selves. They are easy to communicate with, in working this out. We live in a neighborhood with steep sidewalks, heavily used by pedestrians and enforced by the city of Boulder, so it is important to be careful. We also like that they seem to have very careful, thoughtful and efficient workers, using human powered shovels in out small spaces rather than trying to drive through with ATVs or snowblowers over yards and sprinkler heads as some of our neighbors' providers do. And they are quiet, which is nice since they often come early in the morning after overnight snowfalls, which keeps the sidewalks clear longer, with less ice to be faced by pedestrians. So far this first season there has not been a single glitch and I foresee using them as long as they have this service. Looking at their website, you can see the variety of other services they can provide. We may need to expand into some of these categories in the future and I would feel confident doing that. Cost is dependent on how many times it snows each season and overall depth to be removed each time. It seems to be equitable. Yes, the cost was higher this year than any of the last several, given that our snowfall has been happily returned to more normal levels to fill some of Colorado's reservoirs to alleviate the drought conditions. Yet we must find a way to move it off of pedestrian walkways and in Boulder, the home owner/resident component is responsible. It would be nice if the city could do as well with our streets but of course our taxes would pay for that, though I expect most people would like to see that happen someday.

I have learned that a good chimney sweep is not easy to find. General Services Corporation's Jon has been my sweep for many years and will remain my sweep until he eventually retires. He is most carefully thorough in the cleaning of my stove. He spends hours painstakingly removing all he creosote buildup in the flue and, just as important, patiently cleaning every component of the stove. Jon is most knowledgeable about chimneys and wood stoves and freely shares his invaluable knowledge with me. The cost for his work is more than reasonable. Plus, GSC's office administrative staff is most congenial. I will check out the company's other services soon. No doubt they are as good as their chimney cleaning services!
