""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

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
"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!"

Family owned and operated Electrical contracting company, servicing residential and commercial clients. Specializing in back-up generators, full rehabs, remodels and additions. We also have bucket truck service available. We are Licensed and insured in most metropolitan cities and counties in Maryland, DC, Va. Minimum service charge applies per service call.
"Larry and his crew upgraded our under cabinet lighting with new LED lighting, and specialized outlet. Not only was our home and its contents treated as if they lived here, the job was done professionally. So much so, that the only issue we had was when the switch/outlet face plate screws came loose. I didn’t even bother calling Larry, I tightened them myself. The lighting is on, literally 24 hours per day since the install, with zero issues. Love these guys."

"We recently have our basement finished. I was looking for a trusted and reliable contractor for quite a while. I feel very fortunate that finally I found one. The first time I met Syed from Stellar Remodels company, his honest response left me a deep impression. He is approachable and knowledgeable and experienced in project management. He has worked for many years in the construction field. Syed laid out the entire process very simply for us to understand. It was a very straightforward process. The price he offered was reasonable and great. The construction team led by Ainea was incredible responsive and prompt throughout the entire process. They were great getting back to us with answers to all our questions, and flexible with scheduling. The workers were always on time, nice, kind, and respectful of our home. When we had concerns or issues, they quickly resolved them with extreme professionalism and competence. They did an excellent job from many angles. The transformation has exceeded our expectations. Their work is meticulous and thorough. Their ability to get inspections and necessary permits so smoothly made the entire experience stress-free for us. After a couple of months when the job was done, and I couldn’t be happier with the final finished product which took me by surprise. The finishing product was extremely neat and professional with great attention to detail. The transformation exceeded our expectations.

"If I could give this company a 6 out of 5 stars I would! They did a fantastic job overhauling my mother's deck, back patio, fencing, and front portico. All of the work was absolutely essential for safety and structural reasons, and I'm so glad I chose OSSA to do the work. My mother has Alzheimer's, which presented additional issues, but the entire crew was incredibly kind, respectful, and understanding of the unique challenges they faced. They were responsive and kept me aware of everything regarding the job along the way. My mother is so pleased, and I have the peace of mind that all of her outdoor space is safe, beautiful, and accessible. I will be hiring OSSA to do some work in my own home, as I look to make necessary improvements in the future. I've told everyone I know how how wonderful they are. 6 out of 5 stars!"

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
