"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

"Project Management Issues & Pending Renovation Work. I 100% agree with one of the previous reviews and, unfortunately, am experiencing the same issues that have caused unnecessary delays and frustration. While the quality of work itself is good, the project management leaves much to be desired. My bathroom renovation started on December 1st, 2025, with a promised completion time of two weeks. It has now been almost a month, and the project is still not finished. I would admit that I am responsible for one week delay in replacing a bathtub. Throughout this process, I have received little to no communication ? no daily updates and not even consistent weekly updates ? regarding the timeline or the scope of work being completed. This lack of communication from the project manager, Orkhan, has caused unnecessary delays and frustration. Coordinating with both the crew and management has been extremely difficult, and the project manager?s attitude has at times been rude and unprofessional. "

He was very helpful on suggesting were I could purchase my cabinets and countertop at reasonable prices. Gus also did whatever I asked and even gave suggestions on some things because this was my first venture on doing anything like this. He was very professional and left my house clean, once he was finished for the day. Always on time and communicating which is very important to me. I know who I’ll be calling on my next project!!"

FAQs for addition to existing structure building service projects in Gunpowder, MD

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
