    When I first met with Scott at Griffin Decks & Covers, he told me that our new deck build would…read more"change how we live!" I didn't understand it at first, but it's the truth. I never thought replacing our deck would actually change how we lived, but it has! Our old deck was falling apart, and while we used it, it was definitely an eyesore for us. Ever since we built our new deck, my family has eaten outside on it almost every evening we have been home. We go out on it many mornings and evenings now. We absolutely love it! It has brought our family together. We spend more time with one another and more time outside. I understand it now; it truly changed how we live! Scott had so many great suggestions to improve our deck, and we are glad we chose to work with Griffin Decks & Covers! They loved our deck so much that they asked us if they could have it professionally photographed for their portfolio. These pictures are the result. Our family is so grateful we worked with Griffin Decks & Covers. Our new deck is amazing, the pictures speak for themselves!

    Adrian is incredibly talented, thoughtful, and takes tremendous pride in his work. From our first…read moremeeting, he was a pleasure to work with, easy to communicate with, dependable, and genuinely invested in making sure every aspect of the project was done right. He took the time to understand our vision, offered creative solutions along the way, and consistently delivered on every commitment. Our project included a new ipe deck, a rebuilt upper patio, installation of a large sliding glass door, modifications to our existing barbecue area to accommodate the new elevation, and renovations to our fireplace. Adrian approached every phase of the project with exceptional craftsmanship, creativity, and meticulous attention to detail. He communicated with us throughout the process, kept us informed every step of the way, never cut corners, and took great pride in the quality of his work. The finished result exceeded our expectations and transformed our outdoor space into a beautiful extension of our home that we look forward to enjoying for many years to come. We especially appreciated how seamlessly Adrian coordinated with our interior flooring contractor to ensure the installation of the new sliding door and hardwood flooring came together perfectly. (A quick shout-out to Randy, Michelle and the amazing team at Custom Flooring Specialists for working together so seamlessly.) We feel incredibly fortunate to have found Adrian and Trinity Outdoor Design. It's rare to find a contractor with this level of talent, integrity, professionalism, and commitment to excellence. Thank you, Adrian, and the entire Trinity Outdoor Design team for your hard work and dedication. We couldn't be happier with the outcome and wholeheartedly recommend Trinity Outdoor Design to anyone looking for exceptional craftsmanship, outstanding communication, and a contractor who truly cares about delivering an exceptional finished product.

    I'm incredibly happy with the work Trinity did on my home. We didn't have a very big job, just…read moresome fascia boards and soffits that were water-damaged and falling off our back roof line. Unlike other contractors who bid on the same job, Trinity carefully examined the issue to understand possible root causes, and then talked me through exactly what they would do and why it would prevent the issue from returning. Trinity's bid wasn't the cheapest, but their reputation and communication made me much more confident in the investment, and I'm glad I chose them over the cheaper options. I highly value communication in a job like this, and Adrian exceeded all my expectations. He talked me through all the options, and shared regular updates about the start date and what to expect. Antonio did a great job knocking out the work, and the end result looks perfect! I would certainly recommend Trinity to anyone, and I'll be contacting them again when I'm ready to redo my deck and patio!

    I can't recommend Steve Beam's company highly enough! We've been working with Steve for almost a…read moredecade now, and he's consistently exceeded our expectations. We first hired him back when he was known as "Steve Beam Handyman," and it's been amazing to see him grow and expand his services with the launch of Denver Remodels Inc. Over the years, Steve and his team have tackled everything from small repairs (like anchoring heavy drapery hardware into our finicky plaster walls) to major renovations (like restoring the exterior of our 1908 Craftsman). One of our favorite projects was transforming our mudroom by removing a wall and building a custom breakfast nook. This was a complex project, but Steve's expertise and creativity shone through. He even suggested a design element in the booth walls that perfectly complemented the Craftsman lines of our home - it's those little details that make a huge difference. What we think truly sets Steve apart is his incredible craftsmanship, creativity, and his consultative approach. He takes the time to truly understand your vision and offers expert guidance throughout the design process. Whether you're tackling a small project or a major renovation, Steve's deep knowledge and experience are on display with every project he does. He's always there to answer questions, offer suggestions, and steer you in the right direction, ensuring that the final result is even better than you imagined. His team is equally fantastic - professional, efficient, and incredibly skilled. If you're looking for a reliable, knowledgeable, and truly exceptional remodeling experience in Denver, look no further than Steve Beam and Denver Remodels Inc. They're a standout and I'm so glad we found them.

    Steve and his team did a wonderful job completely redoing our master closet and mudroom entryway…read moreshelves. The work took longer than we initially estimated, but Steve communicated with us throughout and was responsive to questions/requests. They are not the cheapest, but you get what you pay for. I can tell these shelves will last a long time!

    UPDATE: Juan threatened my personhood & property - to illegally trespass on our property & remove…read morethe new fence & gate, which would also result in theft, as he removed our old fence & gate. I've been advised to report him to Denver Police & my attorney. ---- Over-promise & Under-deliver, with a side of machismo - by the owner: Juan. ----- It all started innocently, when I called Kim, the receptionist, for an estimate in late Sep or early Oct. Instead of sending a person out for an estimate, she told me all she needed was photos of my existing fence & gate, and from there, she'd create an estimate. At no point did she ask me for measurements, and - given I'm not in the fencing, gate, construction, painting, or staining industry - I trusted her & her boss, Juan, as well as foreman Raul and Ruin to guide me through the process. This is, after all, why I hired the job out, and hired what I thought were professionals. Instead, on the initial scheduled day, it came to my attention that they only purchased enough materials for a 6-foot fence & 6-foot gate, when it was clear - from the photos - that the fence was higher than the gate (8-feet). Raul & I canceled that job, and we re-scheduled from Mon 10/9 to Tue 10/17. In parallel, I was told by Kim that she/they could easily match the existing stain on my fence/gate, and I need not worry about finding a color. This was also untrue. After the reschedule, Kim asked me to find photos of stains I liked. I started on Home Depot, and they had hundreds, if not thousands, of brands, types of stains (oil-based or water-based), and colors. I had no idea where to start. Given I was hiring professionals - or so I thought - in order to narrow it down, I went to JCQN's Yelp page, and found photos of their past/sample work that I liked. I took photos of the fences & gates I liked - including style & color, and changed my initial fence/gate design from vertical pickets to horizontal, to be more modern. And I decided on a natural redwood stain, and sent photos of both the style I desired, and color. Kim & I resolved the initial measurement misunderstanding, and she was diplomatic, professional, and apologetic, acknowledging she should've explained the material measurements on the estimate, and asked me to measure & verify. Yes! Again, the reason you hire professionals, is for them to guide you with their experience. If I wanted to DIY, I would've gone to Home Depot myself, rather than to Yelp. I did not have the time - or interest - to DIY, which is why I trusted JCQN's multiple reviews, and nearly 5-star status. WRONG! Just like my beau has consistently been telling me - don't trust the reviews. I learned this lesson the hard way, with this company. Tue 10/17 came & went, and Ruin & another gentleman installed a great looking fence & gate - this time, with the correct measurements. Though I wanted to have it stained & sealed on the same day, fearing this exact situation, Kim told me the owner, Juan, said that's not possible, and the wood needs to "sit" for "one week" then it moved to "one and a half weeks," which raised suspicion. (Home Depot's paint/stain & lumber departments told me this was BS last night, as I suspected. If the wood is cedar - as I was told it would be, not fabricated, it does not need to sit before staining.) According to Juan/Kim, I had to wait 1-week, then 1.5-weeks, then only a few days to stain/seal. We scheduled it for Fri 10/20. Fri 10/20 arrived, and Kim canceled, saying Juan was too busy. I pulled rank. Then Juan was magically going to show-up after all. He arrived, with the wrong stain - not the one Kim & I discussed, and I selected. Juan attempted to gaslight & blame me - for his mistake - rather than accepting accountability & owning it, and that story is too long for the character limits of Yelp, unfortunately. Juan blamed me - the female customer. Juan blamed Kim - the female employee, including blaming her age: "she's only 20," vs. his "20-years of experience at age 50". Juan blamed me: "I only want to make you happy," attempting to imply I wouldn't be happy with my initial redwood stain selection, and I should go with the cedar/natural he brought, thinking he could manipulate me, in order to fix his mistake. It was a huge mess. Juan then refused to reschedule the job (something about his personal affairs & if he doesn't repair his son's house by next Tuesday, he'll "go to jail"), and now I'm stuck with a beautiful raw, wood fence & gate - that will mold & become useless the minute it rains or snows. Kim negotiated with Juan to refund me the $1,800 I paid for the fence & gate, but neither one of them can refund me the $1,840 worth of my billable *TIME* (that I can never get back) that I wasted on this nightmare. Luckily, I now have 1 other contractor scheduled for Monday, and 3 on stand-by, should that fall through, given the weather is getting colder, which is not ideal for staining.
