"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"We had already hired Pi Kitchen and Bath Shop Frederick to remodel our kitchen, and because of the outstanding job they did, we hired them again, this time to remodel our master bathroom. They did a phenomenal job. From design to the selection of materials, Pi K&B Store made my dream bathroom a reality. Their crew was knowledgeable, punctual, and a pleasure to work with. I highly recommend Pi K&B Store without any reservation to anyone who wants quality workmanship. Pi K&B Store is a company that prides itself on meeting the customers' needs with professionalism and courtesy."

"Thank you James Im, Antonio and crew for an amazing experience and a job well done! It is rare these days to find a home improvement company that you can trust from beginning to end. AHC staff and representatives ensured that every detail from estimates, to coordinating delivery of materials and quality control of installation was performed to the highest standards and exactly on time. James and Antonio/crew were attentive to our every question and concern, and in the end made the experience with AHC a memorable one worthy of the highest level recommendation. Bottom line: If you choose any other roof replacement contractor - you will be making a mistake!"

"This is a wonderful company that gives excellent, timely, and quality service for a variety of home needs. Roland always hires the best professionals based on the project you need done and gives you a comprehensive plan of what it takes to complete. I’ve hired Blue Sky for number of projects including installation of a home sauna that required additional electrical work and have always been completely satisfied. As long as they are open, I’ll be using this company for all my handyman needs."

"It went well. Mario came out promptly to access the damage to my basement and gave me an estimate that was within my budget. The work was scheduled and completed within a week. The guys Antonio and Daniel repaired drywall, baseboards, shoe molding and replaced the vinyl flooring in the bathroom. They also painted two large walls. The guys did an excellent job matching the stain on the shoe molding. And I just love the bathroom floor...what a great job. The job was scheduled to be finished in one day but they had a problem finding the shoe molding that matched. They were back the day and all is well. What a great job guys. I will definitely use their services again."

FAQs for addition to existing structure building service projects in Rocky Ridge, 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.
