We keep pools clean, safe, and running smoothly all season long. Our focus stays on steady cleaning, balanced chemicals, careful seasonal openings, and fast repairs so your pool in Maryland, DC, or Virginia is always ready to use.
We handle skimming, vacuuming, and brushing to clear out leaves, algae, and debris. Our team tests and adjusts pH, chlorine, alkalinity, and calcium hardness every visit to prevent corrosion, stains, and cloudy water.
We stick to a regular schedule—weekly or bi-weekly—depending on your pool’s needs. We clean or backwash filters, empty skimmer baskets, and check tile lines and lights.
Using professional equipment and products helps us keep swimmers safe and avoid chemical swings. Our trained technicians always document readings and work done, so you know exactly what’s happening with your pool.
When it’s time to open your pool for the season, we safely remove covers, reconnect equipment, and refill water to the right level. We check for winter damage like cracked plumbing, loose coping, and heater issues before starting everything up.
We shock the pool, balance chemicals, and run the filter until the water’s clear. We also set heater and automation controls, and replace worn gaskets or O-rings. In Potomac and Montgomery County, we pay special attention to spring pollen and runoff to keep algae away.
Letting us handle your pool opening lowers the risk of missed issues and expensive repairs later. We take care of everything, so you can just enjoy your pool.
Every service visit, we check pumps, filters, heaters, salt systems, and automation. We look for leaks, corrosion, weird noises, and pressure loss that could mean trouble.
We also do routine maintenance—lubricating bearings, checking belts, tightening electrical connections. If something needs fixing or replacing, we offer clear options, including energy-efficient upgrades.
We recommend scheduling annual equipment checks in addition to routine visits. Our team at Dolphin Pool Services handles diagnostic testing and quick repairs to keep your pool running strong.

We take care of full pool renovations and targeted upgrades that improve safety, cut costs, and extend your pool’s life. You can count on clear steps, set timelines, and professional crews working throughout Maryland, DC, and Virginia.
We start with a full inspection to spot cracks, tile damage, leaks, and outdated equipment. Then we recommend the right repairs—replastering, tile and coping replacement, pool deck resurfacing, and equipment upgrades.
We offer energy-saving options like variable-speed pumps and high-efficiency heaters to help with utility bills. Our team coordinates scheduling, permits, and any needed subcontractors to keep your project on track.
For homeowners in Potomac and nearby, we provide clear estimates and a solid warranty on our work. We usually recommend replacing equipment older than 10–15 years and resurfacing every 10–20 years, depending on how your pool’s used.
We’re fully licensed and insured for Maryland work, and we’ve got plenty of references and before-and-after photos from local projects. Our team handles permits, offers written estimates, and stands by our timelines and warranty.
At Dolphin Pool Services, we focus on trained technicians, reliable crews, and straightforward communication. We know pools inside and out, and our experience with renovation permits across Maryland, DC, and Virginia means your project is in good hands.
We get a lot of questions about routine tasks, water testing, safe draining steps, equipment care, and differences between above-ground and in-ground pools. We always recommend hiring a professional company like Dolphin Pool Services for reliable results.
Weekly cleaning for a standard residential pool in Maryland usually falls in the $100 to $200 per month range, but that depends on your pool’s size and needs.
Bigger pools, lots of debris, or extra repairs can bump the price up. We suggest getting a written estimate from us at Dolphin Pool Services so you know what’s covered and aren’t surprised by extra fees.
A typical visit covers skimming debris, brushing walls and steps, and vacuuming the pool.
We test and adjust chemical levels, check filter and pump operation, and empty skimmer and pump baskets. Our team follows a checklist and documents everything, so you know what we did and when.
We test water chemistry at least once a week for most residential pools during swim season.
If your pool’s busy or the weather’s hot, we might test two or three times a week to keep chlorine, pH, alkalinity, and stabilizer in check. Our regular service helps keep things steady and prevents algae or equipment damage.
First, check local rules and the pool structure—some places restrict full draining.
If draining’s allowed, lower the water slowly, clean surfaces with the right non-abrasive cleaners, and inspect for cracks or loose tile. We recommend letting professionals handle deep cleaning to control runoff, protect your pool shell, and tackle repairs if needed.
Clean or backwash filters as needed, usually every few weeks or when pressure rises.
Check pump seals, belts, and electrical connections, lubricate moving parts, and replace worn parts right away. Regular winterization, startup checks, and prompt repairs by our team at Dolphin Pool Services help your equipment last longer and avoid expensive breakdowns.
Above-ground pools usually come with simpler filtration systems and hold less water. That means the pumps and filters don’t need as much heavy-duty attention.
On the other hand, in-ground pools need more frequent structural checks. We also pay close attention to tile care, and these pools often use larger filtration systems, heaters, or automation to keep everything running smoothly.
At Dolphin Pool Services, we customize every maintenance plan for your specific pool type and size. Our goal? To keep your pool clean, safe, and operating efficiently.
