Our Mission Statement: Long Creek Construction, LTD, is to create long term relationships with our customers, suppliers and employees by demonstrating honesty and fairness. We strive for excellence in workmanship and service through friendliness and efficiency.

We also have experience in many other miscellaneous construction fields. But, don't trust us just because of our experience, try us for yourself and let us prove to you what we can do!

"Amazing job! Carlos and his team of experts went the extra mile to ensure that I got exactly what I wanted. Carlos reviewed details of the contract with me and we worked together to make adjustments if I had minor changes during the remodel. Long Creek construction workers, plumber, and electrician were timely, efficient, and consistently worked M-F and on some weekends. The result of Long Creekâ s work is a beautiful 600+ sq ft bedroom and bathroom. The bathroom is absolute nirvana: beautiful black matte porcelain tile floor, a black porcelain tile accent wall and shower accent, with luxury polished cream tiled walls with hints of black within. The shower has 6 shower heads, including 1 static rainfall, 1 hand-held shower head along with 4 side-wall mounted pressure point shower heads. The mirror has a defogger button and three-way light dimmingâ seriously? On either side of the mirror are beautiful sconce lights. The Woodbridge freestanding jetted tub is the final touch to give the bathroom a total spa-like atmosphere. And the vanity has spring-loaded closures for the cabinet doors and drawersâ no detail was overlooked. Long Creek did a spectacular job increasing the size of the primary bedroom from previously 200 sq ft to over 600 sq ft. It features two walk-in closets, beautiful solid hardwood floors, a high ceiling with recessed lighting with dimmers. The ceiling fan is a top-quality 8000+ CFM beauty. The bedroom has a large sitting room that breaks up the space very well and gives me and my husband the feeling that we are in an upscale hotel suite instead of a bedroom. Long Creek Construction is a professional, efficient, team of experts. They worked every dayâ even days with inclement weather. They donâ t waste time, they are incredibly accommodating, and they do things right! I am so impressed with the level of regular communication, exceptional quality of work, and timeliness of Long Creek Construction. I am extremely happy with the work and ! will definitely choose them again!"

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."

"I am writing to formally express my deep dissatisfaction with the recent retaining wall replacement project completed by John Krause Construction (JKC) at my property. After reading positive reviews and receiving an estimate that, although over my budget, seemed reasonable for the work involved, I made the decision to hire JKC. Unfortunately, this has proven to be a significant mistake, and I am left extremely disappointed with both the quality of work and the overall experience. Here are the main issues I encountered: 1. Unprofessional Behavior: The crew exhibited unacceptable behavior while working on my property. Not only did I witness them disposing of bodily fluids on-site, but they were also disrespectful and dismissive. when I raised concerns no response was received. I now smell urine when entering and exiting my garage. 2. Unresponsive Ownership: I have attempted to reach out to the owner multiple times to address these concerns and resolve the issues, but my messages have been met with silence. This lack of communication is incredibly frustrating and has only added to my disappointment. The owner refused to speak on the phone since the owner was made aware of the call being recorded. 3. Property Damage: During the construction process, my property was left damaged in multiple areas. This included e.g., landscaping destruction, equipment damage. Personal crew members vehicles being driven through my yard leaving deep tire marks damage. 4. Subpar Quality of Work: Despite the high cost of the project, the final result does not meet the standards outlined in the estimate or contract. No proper grading was completed. Every time it rains pools of water sits in front and behind the wall. The response received was. “we have passed all inspections.  There will be some water pooling while it is settling still. Plus the fact of the hard rain today, it will happen.” The wall has been completed for 2 months. Given the extensive problems, stress and anxiety I have faced. I do not recommend John Krause Construction."

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