"AES Builder & Home Improvements Inc. was absolutely amazing to work with from start to finish! They remodeled our original kitchen, and the results are beyond beautiful. From our very first meeting to the day we spent picking out custom design materials, the entire process was organized, collaborative, and enjoyable. Their coordination and communication throughout the renovation were top-notch! Every contractor who came into our home was professional, respectful, and genuinely cared about their work. They answered all of our questions and kept us informed every step of the way, even when there were small delays. The quality of the craftsmanship truly shows, and our new custom kitchen makes me smile every single time I walk in to cook. We couldn?t be happier with how everything turned out.

Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Best Homes LLC just finished our basement and we could not be happier! The quality of work is outstanding and the team was always on time, happy to be here and great at communicating. Jefry is a great project manager and always takes your input regarding placement of different aspects and fixtures. It was a lot of fun working through picking out different tiles, flooring, cabinets, colors, etc to make the space how we envisioned it. We even got to choose the placement of extra outlets and things to make the space fit for our use. The price was very reasonable, especially after being quoted nearly double from another contractor. Our basement turned out absolutely gorgeous and now we have a functional, finished space with a full bathroom and wet bar included. The team was incredibly accommodating, gave a generous allowance for tile and flooring, etc. The project was finished with the quoted price and on time, and we will use Best Homes LLC as our go-to for any contracting needs. 10/10!"

We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"All the people at Elevate Design and Build were amazing and a pleasure to work with. We doubled the size of our house including tripling the size of the kitchen, knocking out walls to create an open floor plan and added a three car garage with home office over the garage. They even recommended modifications to our original blueprints which were excellent. All their workers friendly and did a first class job. Went totally above and beyond our expectations. One year later we have not had one single problem with any of the work. Total integrity. If any issue came up, the company absorbed the cost - not the customer. Everything they did was done perfectly. We didn't have a single issue or complaint during the entire process. I give them my highest personal recommendation. I would never use anyone else."

Managed Renovations engages with our clients using a couple different business models depending on their needs, preferences, and level of desired participation in some of the required tasks involved with most projects. Some of our clients choose to use our unique construction management services business model to build their project that is distinctive from the typical fixed-price general contractor (GC) approach to construction. For those clients we provide fee-based construction management consulting services to schedule, manage (on-site), and review all the work that our clients choose to have us handle for the project. We connect and contract our clients with our seasoned collection of licensed and insured tradesmen and subcontractors (and our own in-house carpenters) that will provide each of their fixed price costs. Alternatively, some of our clients prefer to have their project built using a typical fixed-price general contractor (GC) approach to construction.

"We recently had our kitchen remodeled by Managed Renovations. The experienceâ from start to finishâ was nothing short of amazing and the finished kitchen is spectacular, exceeding our expectations. The Managed Renovations team, Michael and Natalie, and their subcontractorsâ carpenters, electricians, plumbers, and floor installersâ displayed a level of professionalism, craftsmanship, and attention to detail that was extraordinary. They turned a small, poorly designed 1970s kitchen into a large, beautiful, functional space that is now the heart of our home. Although the project involved demolishing walls and removing the existing cabinets, appliances, and flooring (and replacing them with new cabinets, appliances, and flooring), they accomplished this with minimal disruption to our lives, always leaving our home and the work area clean at the end of the day. Managed Renovations communicated with us throughout, (we could also track every aspect of the project online), making sure we were comfortable with every decision. Their recommendations, whether about design elements or vendors, were always â spot on.â There were no surprises. They delivered what they promised when it was promised, completing our kitchen on time and without any unanticipated costs. Managed Renovations' dedication to excellence and customer satisfaction is truly unmatched. If youâ re looking for a general contractor who will deliver outstanding results, look no further than Managed Renovations."

Abode Construction delivered this and more! Scott provides top notch work, respectful and capable crew, quality customer care, and advice, all for a competitive price. His team, from the estimate to changes for the project through completion of the bathrooms, make the client feel valued. Did everything go as planned? Absolutely not. Some events were unavoidable (e.g. supply delays) but some could have been avoided. However, Scott made sure that we were whole at the end of the day and made good on his 100% guaranteed satisfaction. I now have two updated, modern bathrooms that we all LOVE!

"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."

FAQs for addition to existing structure building service projects in Silver Spring, 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.
