Think you have a leak? Reach out to us right away. We’ll find the problem quickly and walk you through repair options, so you can fix it before things get worse.
We guide you through simple checks you can try at home, and we bring professional diagnostics when needed. When you trust a licensed, local company like us, you get fewer guesses, better fixes, and repairs done right to local codes.
We find leaks fast and fix them right, so your pool structure, equipment, and water stay protected. Our team covers Potomac, MD and nearby Maryland, Virginia, and DC areas with trained technicians and reliable tools.
Watch for daily water loss of more than 1/4 inch; that usually points to a real leak, not just evaporation. Wet spots in the yard, weird algae even with balanced chemicals, air in the pump basket, low pump pressure, and cracks or hollowness around lights, skimmers, or tile lines are also red flags.
Check skimmer throats and return fittings for constant drips. Look at pool equipment pads and visible plumbing for any dampness. We suggest tracking your water-loss rate for a few days and turning off auto-fill devices to double-check. If you spot several of these signs, call us at Dolphin Pool Services for a thorough inspection.
We use a mix of electronic and hands-on methods to find leaks with as little disruption as possible. We pressure test plumbing lines to find hidden failures.
Our sonar listening devices and acoustic gear help us hear water movement in pipes under decks or inside walls. We do dye tests when we suspect leaks around fittings, lights, or tile—no guessing.
For vinyl or fiberglass pools, we use LeakTrac-style electronic tracers from the deck. We also use gas or helium detection to track down tiny plumbing leaks. These methods help us figure out if you need a simple patch, a line replacement, or something more.
Once we find the leak, we pick the least invasive, longest-lasting fix. If you have a small leak in a light niche or skimmer, we use professional patches and resin that bond to plaster or fiberglass.
For plumbing issues, we repair or replace lines using durable materials made for Maryland weather. If the pool structure or finish needs work, we handle renovations—resurfacing, tile replacement, or equipment upgrades—so repairs fit your long-term maintenance plans.
We handle permits and all the paperwork when needed. We always follow local codes and keep your warranty safe.
Waiting to fix a leak just makes things worse. Even a small leak can erode soil under the deck, mess with electrical lines, and put stress on your pumps and heaters.
In Potomac, freeze-thaw cycles and local soil can make hidden damage much worse, fast. Catching leaks early keeps your finish in good shape, avoids big renovations, and keeps your pool chemistry steady.
We recommend scheduling a leak inspection as soon as you notice something off. Our quick response helps you avoid equipment failure and expensive repairs, so your pool investment stays protected.
We handle every part of pool care—from weekly cleaning and chemical balancing to full-season openings and renovation planning. Our team focuses on reliable results, straightforward communication, and using trained techs with quality parts.
We offer weekly and biweekly maintenance plans that cover skimming, vacuuming, brushing, and tile cleaning. Each visit includes chemical testing and dosing, keeping pH, alkalinity, and chlorine right where they should be.
We track results and let you know if anything needs more than routine adjustment. Filter care and equipment checks are always included.
We inspect pumps, motors, heaters, and timers to catch problems before they cause trouble. If repairs or parts are needed, we give you a written estimate and can schedule work fast.
Our pool opening service gets your pool ready for safe, reliable use after winter. We remove covers, reconnect and check equipment, refill to the right water level, and do a full chemical shock and balance.
We check for winter damage like cracked tiles, stuck valves, or plumbing leaks. During opening, we test and service filters and pumps so your pool circulates efficiently.
If we find leaks at startup, we use our leak-detection methods and offer repair options. We document what we find and recommend any urgent repairs before you dive in.
We handle plaster resurfacing, tile and coping replacement, and full equipment upgrades to boost performance and lifespan. Our projects often include replastering, installing energy-efficient pumps, replacing filters, and upgrading heaters or automation.
We start with a site inspection and give you a written scope with materials, timeline, and warranty info. We take care of permits and code requirements for jobs in Maryland and Virginia.
Our crews follow strict safety and cleanup protocols. We also offer upgrades like LED lighting, new tile patterns, and deck repairs.
We answer how to spot leaks, tell the difference between evaporation and real loss, find hidden plumbing problems, estimate inspection time, and explain if draining or decking removal is needed.
Visible water loss beyond normal evaporation is the main sign. If your pool drops more than 1/4 inch per day, you probably have a leak.
Wet or soggy ground near the pool deck, constant damp spots in the lawn, or unexpected algae growth on walls and steps can all point to an underground leak. Air in the pump, low heater pressure, or changes in circulation can mean plumbing or equipment leaks.
Cracks in plaster, gaps around lights or returns, and loose tile or coping often mean structure leaks. We check these spots first when we visit.
Try the bucket test. Fill a bucket with pool water, set it on the top step, mark the water levels inside and outside, and check after 24 hours.
If the pool level drops more than the bucket, you probably have a leak. Track the loss over a few days and after using the pool or heavy rain to see if there’s a pattern.
Season, wind, sun, and temperature all affect evaporation. We consider those when we look at your results.
We use pressure testing to find hidden plumbing leaks. Our technicians isolate and pressurize pipes to spot pressure drops that signal a leak.
Dye testing helps us find leaks around fittings, lights, and small cracks. We release dye near suspicious spots and watch where it goes.
We also use electronic listening devices, hydrophones, and special cameras to find underground leaks and voids under decks. For tough cases, we combine several methods for quick, accurate results.
A basic inspection and bucket test usually take 30 to 60 minutes. If we need to do pressure tests, dye tests, or use electronic listening, it might take 2 to 4 hours.
Complicated underground searches or tricky plumbing problems can take more than one visit. We’ll tell you how long we expect before we start, so you can plan.
Most of the time, we don’t need to drain the pool. Draining can actually harm the pool shell and cost more.
We rarely need to remove decking. We start with noninvasive tests and only remove decking or dig if we confirm a leak and need access for repairs.
Honestly, the location and how easy it is to reach the leak make a big difference in cost. If we spot a surface leak, it’s usually simpler and less expensive for us to handle than one hidden deep underground or within the pool’s structure.
The tools and tests we use also play a role. Sometimes, we need to run pressure tests, use electronic devices, or send in cameras—these methods bump up accuracy, but they can add a bit to the bill.
The type of repair and materials matter, too. Maybe the job calls for us to replace pipes, patch up cracks in the pool shell, or even rebuild a section of the pool’s decking. Each situation brings its own set of labor and material needs.
At Dolphin Pool Services, we really focus on getting leak detection right the first time and making repairs that last. If you want peace of mind and a pool that’s ready for summer, we’re here for you.
