Review the comparison below, or contact our team and we can help determine the maintenance schedule that is right for your pool.
Weekly Pool Maintenance
Best suited for pools that benefit from more frequent professional attention, including those with heavier use, greater debris exposure, or homeowners who prefer a more hands-off approach to routine pool care.
Pool Opening With Follow-Up Care
Opening Service
Removing and storing the winter mesh cover at the owner’s direction, removing winterization plugs, reinstalling fittings and deck equipment, and returning the filtration system to operation.
​
Water & Pool Preparation
Adding sanitizer, balancing water chemistry, clearing debris, and vacuuming the interior pool surface.
​
Follow-Up Care
Lothorian’s current opening package includes two follow-up visits to help bring the pool to swim-ready conditions.
​
Opening the pool is only the first step. The goal is to help get it ready for your family to actually use.
Professional Pool Closing & Winterization
Pool Closing
Proper winterization helps protect your pool and equipment through Maryland’s colder months. Lothorian prepares the pool and its systems for the off-season so everything is properly shut down before freezing weather arrives.
What’s Included
Lothorian prepares equipment and plumbing for winter, lowers the water to the appropriate level, winterizes circulation, filtration, and heating systems, and clears plumbing lines with compressed air. The pool is also cleaned and vacuumed, water chemistry is balanced, winter chemicals are added, and the owner’s pool cover is installed.
Why It Matters
A thoughtful closing protects more than the appearance of the pool. It helps protect plumbing, equipment, and pool systems through months of inactivity and supports a smoother return to operation the following season.
Service Starts With Understanding Your Pool
A successful service relationship begins with understanding the pool, the property, and your expectations.
Whenever possible, a member of Lothorian’s leadership team meets with new maintenance clients before routine service begins. This allows us to become familiar with the pool and equipment, review any existing concerns, answer questions, and establish a clear understanding of how the pool should be cared for.
It also gives you the opportunity to know the company and people you are trusting with regular access to your home.
We believe better service starts with familiarity, communication, and a shared understanding from the very beginning.
A Team Behind Every Visit
Your maintenance technician may be the person you see most often, but they are supported by an entire team focused on the care of your pool. Behind each visit are service managers, schedulers, office professionals, equipment specialists, renovation and construction experts, and company leadership working together to support communication, service records, technical needs, repairs, and scheduling. Whenever possible, Lothorian also strives for technician consistency so the person caring for your pool becomes familiar with its equipment, history, and normal operating conditions. The result is the personal attention of a dedicated technician, backed by the knowledge and resources of an established pool company.
We Get to Know Your Pool
Every pool has its own patterns, and familiarity matters. When the same technician cares for a pool regularly, they begin to understand how the water behaves, how the equipment sounds, how quickly debris accumulates, and what conditions are normal for that property. That familiarity can make it easier to recognize changes in water chemistry, circulation, equipment performance, water level, surface conditions, or other developing concerns. Recurring maintenance cannot prevent every repair, but it provides something valuable: consistent, knowledgeable attention from a team that understands what is normal for your pool and can recognize when something has changed. Over time, we do more than service your pool. We get to know it.
Support When Your Pool Needs More
Routine maintenance is only one part of caring for a pool. When something changes or a problem develops, having an experienced team already familiar with your pool can make a meaningful difference. Whether the issue involves cloudy water, an equipment concern, an unexpected leak, or a component that has reached the end of its service life, Lothorian’s expertise extends well beyond routine maintenance. Our team provides equipment service, troubleshooting, repairs, and technical support backed by decades of experience designing, building, and caring for pools. For maintenance clients, that means you already have a trusted pool company to call when additional expertise is needed—one that understands your property, your equipment, and the history of your pool. That continuity is one of the reasons so many of our client relationships last for years, and in many cases, decades.
Clear Communication & Helpful Guidance
Pool ownership can become technical quickly, but understanding what is happening with your pool should not feel complicated. When our technicians identify something that deserves attention, our goal is to explain it clearly—what we are seeing, why it matters, whether action is needed, and what the next step should be. That same approach applies to questions about water chemistry, equipment, operation, repairs, and future improvements. Our role is to give you clear, practical guidance so you can make informed decisions with confidence.
Simple, Comprehensive Maintenance Plans
Pool maintenance should be easy to understand and straightforward to manage.
Lothorian’s maintenance plans are designed to provide comprehensive seasonal care with a clearly defined scope of service. Your opening, weekly or biweekly maintenance, balancing chemicals, and closing are bundled into one plan and billed in two simple payments.
The result is a more predictable approach to pool care, with fewer surprises and a clear understanding of what is included throughout the season.
Support Through Every Stage of Pool Ownership
The needs of a pool naturally change over time. Equipment ages, technology improves, finishes wear, and the way a family uses the space may evolve.
Lothorian’s experience extends beyond routine maintenance to equipment service, repairs, modernization, renovation, and new construction. That broader expertise allows us to support clients as their pools change, without requiring them to start over with a new company at every stage.
For long-term clients, that continuity can mean working with a team that already understands the pool, its equipment, its service history, and the priorities of the homeowner.
A Relationship That Lasts
Pool ownership changes over time, and the needs of the pool often change with it. Some clients first come to Lothorian for design and construction, others for maintenance or service. Over the years, that relationship may grow to include seasonal care, equipment support, repairs, and eventually larger updates to the pool or property. What matters is the continuity. Our team can remain familiar with the pool, its history, and the people who use it, providing support as needs evolve. Building a pool may be a project. Caring for one is a relationship.
Experience That Keeps Evolving
Since 1980, Lothorian has cared for pools through decades of changing equipment, technology, materials, and Maryland swimming seasons. That experience gives our team a deep understanding of what works, what lasts, and how to respond when something does not.
We continue building on that knowledge through ongoing training, employee development, stronger systems, better communication, and continued improvements to the customer experience.
Each season gives us another opportunity to refine how we work, strengthen our team, and provide an even better level of care for our clients.
