You want a safe, clean pool that works all season. We make that simple for Centreville homeowners.

We see common issues in Northern Virginia—equipment wear, algae risks, and the challenge of seasonal opening and closing. Our team explains which services keep your pool reliable, so you know what to expect.
You’ll get clear steps and real costs. We also offer options for upgrades, so you can pick the right level of care for your yard and budget.
We base our advice on local experience and proven methods. We can handle routine care or bigger fixes when things go wrong.
We focus on keeping pools safe, clean, and ready for swimming. Our team handles regular cleaning, equipment care, chemical balance, and seasonal opening and closing.
We clean skimmers, vacuum floors, and brush walls on a set schedule. This routine stops algae and debris from building up.
During each visit, we skim the surface, empty baskets, vacuum the pool, and brush tiles and steps. We inspect pumps, filters, heaters, and timers every time we’re there.
We check pressure gauges, backwash or clean cartridge filters, listen for odd pump noises, and test heater startup. We log what we find and recommend repairs before small issues turn into big headaches.
We use professional-grade tools and parts. Our team follows manufacturer guidelines, and we catch worn seals, brittle hoses, or failing valves early—so your pool avoids downtime.
We test pH, chlorine (or alternative sanitizer), alkalinity, and calcium hardness at each service. Keeping pH between 7.2–7.6 and free chlorine at the right level protects swimmers’ eyes and your pool’s surfaces.
We balance alkalinity and calcium to protect plaster and equipment. If the levels are off, we add the right dose of acid, alkalinity increaser, chlorine, or stabilizer.
We also shock pools after heavy use or rain. We document readings and chemicals used, so you see trends over time.
For pools with salt systems, we check salt ppm and cell condition. If you keep seeing swings in your pool chemistry, we recommend getting professional help—improper dosing can really mess up surfaces and gear.
We handle spring openings by removing covers, refilling water, reconnecting equipment, and restarting pumps and heaters. We inspect lines, valves, and heaters for winter damage.
We clean filters before regular service resumes. For closing, we winterize pumps, blow out plumbing lines, lower water levels to protect skimmers, add winter chemicals, and install a secure cover.
We tailor this process to your pool type and local Virginia freeze risks. You’ll get a clear checklist and a written estimate for openings and closings.
Letting us handle your seasonal pool care reduces the chance of freeze damage, algae blooms, or expensive spring repairs.
We offer durable renovation options, fast equipment upgrades, and service across Virginia, Maryland, and DC. Our team handles resurfacing, equipment replacement, and more—all with licensed technicians.
We renovate pools using proven materials like Diamond Brite plaster, tile replacement, and modern coping. We check for surface wear, leaks, and structural issues before recommending a plan.
That plan may include resurfacing, new tile, coping replacement, deck repair, or full replumbing. We replace pumps, filters, heaters, and automation systems to boost efficiency and lower energy use.
We provide written estimates with parts, labor, and timelines. For tile and finish choices, we bring samples to your home so you can see the options in person.
We handle permits and coordinate with subcontractors if needed. Our crews follow local codes and test everything thoroughly after work. We recommend routine checkups to protect your investment and extend the life of your renovation.
We serve Centreville and other Fairfax County neighborhoods, plus parts of Maryland and Washington, DC. Our typical service areas include Fairfax, Loudoun, and Montgomery County communities.
We schedule seasonal openings, closings, and emergency repairs across state lines. Our service routes help us keep response times short for equipment failures.
For larger renovation projects, we handle logistics—permitting, inspections, and material delivery. We work with property managers, HOAs, and homeowners to fit projects into local rules and timelines.
If your property sits near a county border, there’s a good chance we already service nearby addresses. Just contact us to check availability and get a quote for travel and timing.

Our crews spot hidden issues—bad valves, failing heaters, subtle leaks—before they become big problems. We document our work with photos and a final checklist, so you know exactly what changed and why.
We offer tailored maintenance plans, transparent pricing, and emergency response options. Choosing us protects your pool’s value and keeps your water safe for everyone.
We get questions about service frequency, weekly tasks, fixing cloudy water, algae removal, cost-cutting tips, and troubleshooting pumps and filters. We always recommend using a professional company like us, Dolphin Pool Services, for accurate diagnosis and safe treatments.
We recommend weekly service during swim season for most residential pools. Weekly visits help maintain chemical balance, skim debris, and catch equipment issues early.
For low-use or covered pools, every two weeks can work, but we suggest monthly testing between visits. Regular professional testing keeps small problems from turning into big repairs.
We test and adjust chlorine, pH, alkalinity, and calcium hardness. We skim the surface, vacuum the pool as needed, and brush the walls and steps.
We clean or backwash filters when required and inspect pumps, heaters, and chlorinators. If we spot issues, we document them and recommend repairs or upgrades.
We start by testing water for pH, alkalinity, and sanitizer level. If levels are off, we correct them and clarify the water with a flocculant or filter aid.
We check and clean the filter thoroughly and run the pump until the water clears. To prevent recurrence, we keep chemical levels steady, maintain the filter, and schedule regular checks.
Low sanitizer, poor circulation, and high phosphate or nitrate levels often cause algae. Warm temperatures and sunlight only make things worse.
We shock the pool with a high-dose sanitizer, brush all surfaces, and run the filter until the water clears. For heavy infestations, we use an algaecide and repeat brushing and filtration. Our trained team ensures safe chemical handling and complete removal.
We suggest preventive actions: keep the pool covered when not in use, run the pump on a timer, and clean filters regularly.
Schedule seasonal inspections so you can catch small issues early. Working with us at Dolphin Pool Services lowers long-term costs through proper equipment tuning and service plans tailored for your pool.
Start by checking the pump basket and skimmer for any debris. Make sure the pump lid seal sits tight.
Take a look at the filter pressure gauge. If the reading looks high, your filter probably needs a good cleaning or backwashing.
If your pump runs but the water flow seems weak, look for air in the system or closed valves. Sometimes, a worn impeller might be the culprit.
Can’t figure it out? Just give us a call. At Dolphin Pool Services, we’ve got the right tools and the know-how to safely diagnose any motor, plumbing, or filter issues you’re facing.
