Our Story
Many plumbing companies operate on a franchise model or at a nationwide level. As a homeowner, this means you’re often paying a portion of franchise fees, along with the costs of multi-level management.
The advantage of choosing Precision Plus Plumbing is that you’re working with a “true” local, family-owned business. This ensures personalized service and expertise without the extra overhead costs that larger companies pass on to their customers.

What sets Precision Plus apart is that we’re the only plumbing company with a Licensed Master Plumber on staff full-time,
along with a dedicated water damage restoration department. For pressure testing specifically, this means the certificate you receive is signed by a PA-licensed master plumber – the level of credential PECO, township inspectors, and real estate underwriters expect to see.

Why Precision Plus
Why Chester County Homeowners Choose Us Over Franchise Plumbers
Many plumbing companies operate as franchises. As a homeowner, you end up paying for their franchise fees, multi-level management, and corporate marketing – on top of the test fee
Precision Plus is different.We’re a local, family-owned business. No franchise overhead. No call center dispatching a random technician. When you call us, you get a master plumber who has worked with PECO and Chester County township inspectors for 25+ years and knows exactly what each one wants to see on the certificate.
What makes us truly unique: We’re the only plumbing company with a Licensed Master Plumber and a Water Damage Restoration department under one roof. If your pressure test fails and we have to open a wall or floor to repair the leak, we fix the line AND repair the damage – one company, one call, and we re-test before we leave.
Every pressure test includes a FREE written certificate of test + PECO/inspector coordination ($149 value) – the documentation that closes out your permit, satisfies your buyer, or restores your gas service.

Our Work
Our Work in Action Across Chester County
Real pressure tests completed by our master plumbers – PECO reconnects, permit close-outs, and real estate certifications across local homes.
Local Expertise
Different Homes. Different Problems.
Real pressure-test situations our technicians handle across Chester County — because every community has different housing stock, different code histories, and different reasons for needing a certified test.
West Chester
19380, 19382
→ REAL ESTATE TRANSACTIONS ON HISTORIC HOMES
West Chester’s historic borough is one of Chester County’s most active real estate markets, and buyer-side inspectors on Victorian and Federal-era homes routinely flag gas systems for pressure testing. These homes often have decades of capped-off branches from old conversions — gas lines that were abandoned but never properly removed. We isolate and test the live system, identify and properly cap any phantom branches, and deliver a certificate the buyer’s lender and inspector both accept. Most West Chester closings move on schedule.
Phoenixville
19460
→ MULTI-UNIT TESTS IN CONVERTED MILL BUILDINGS
Phoenixville’s converted mill and factory loft buildings often share a single PECO meter bank with branch lines feeding multiple units. When one unit goes through a permit close-out or real estate sale, that unit’s branch must be isolated and tested separately from the rest. We map the manifold, isolate the affected unit at the riser, perform the test on the isolated branch, and document which sections were tested versus which were outside the scope – exactly what condo associations and mortgage underwriters need to see.
Coatesville
19320
→ AGED UNDERGROUND LINES & PRE-PURCHASE VERIFICATION
Coatesville’s older neighborhoods have steel underground service lines from the 1950s -1970s, and buyer-side home inspectors increasingly require a passing pressure test before closing. We pressure-test the customer-side line above grade where possible, run a separate underground hold test where required, and document the test method clearly so the inspector report has no gaps. If the line fails, we coordinate with PECO and replace the customer-side run in poly with tracer wire — then re-test.
Downingtown
19335
→ POST-RENOVATION & ADDITION PERMIT CLOSE-OUTS
Downingtown’s mix of 1980s-1990s subdivisions sees a lot of kitchen renovations, basement finishes, and rear additions where a gas line was extended, capped, or rerouted. PA UCC requires the modified system to pass a pressure test before the permit closes – and the township won’t issue the certificate of occupancy without it. We schedule around your contractor’s timeline, perform the test to IFGC requirements, and meet the township inspector if requested.
Exton / Malvern
19341 , 19355
→ CSST ACCEPTANCE TESTS ON NEW CONSTRUCTION
Exton and Malvern’s newer executive homes are typically piped with CSST (corrugated stainless steel tubing), which has its own acceptance-test protocol – including verification that the system is properly bonded to the home’s grounding electrode. We perform the pressure test, verify CSST bonding to current code, document both, and provide the bonding photo documentation insurance carriers increasingly require post-installation. Same protocol applies to additions and finished basements where CSST was extended.
Kennett Square
19348
→ PROPANE-TO-NATURAL-GAS CONVERSION VERIFICATION
Kennett Square and southern Chester County have many homes converted from propane to PECO natural gas over the past 20 years. PECO requires a passing pressure test before they activate the meter, and conversions involve enough fittings, valves, and orifice changes that a methodical test is the only way to verify the system is tight. We test the full distribution, verify each appliance is properly converted and operating at the correct pressure, and provide the PECO-ready certificate that gets the meter turned on
Our Process
From First Call to Certified Pass.
Six steps. One visit, in most cases. No second-guessing.
1
You Call. We Schedule Around Your Deadline.
Call (484) 436-4190. Tell us why you need the test - PECO reconnect, permit close-out, real estate closing, insurance request, or post-renovation. We schedule around your deadline. Same-day available for closing and reconnect emergencies.
2
Pre-Test Walk-Through
Before we pressurize anything, we walk the system, verify all appliances are properly shut off and isolated, identify any capped branches or unfamiliar lines, and confirm the test scope in writing. This is where 90% of test failures get prevented - most "failed tests" are really setup mistakes.
3
System Isolation & Pressurization to Code
We isolate the section being tested, attach a calibrated test gauge at an approved riser, and pressurize the system per PA UCC and IFGC requirements (typically 1.5× working pressure or 3 PSI minimum, whichever is greater).
4
Hold Period & Continuous Monitoring
We hold the test pressure for the code-required duration (typically 10 minutes minimum, longer for larger systems or specific PECO requests) and monitor the gauge continuously. Any pressure drop is noted, investigated, and addressed before re-pressurizing.
5
Written Certificate of Test
You get a signed, dated certificate listing the system tested, test pressure, hold duration, result, and the licensed master plumber's signature and license number. This is the document your inspector, PECO, lender, or buyer's agent is asking for.
6
PECO / Inspector Coordination & Sign-Off
If PECO needs to reconnect your service, we coordinate the visit. If the township inspector needs to witness the test, we schedule and meet them. If your real estate transaction needs the certificate uploaded to a portal, we send it directly. You're done.

Common Questions
Frequently Asked Questions
Everything Chester County homeowners ask before scheduling a gas line pressure test.
What pressure do you test at, and how long is the hold?
For most residential systems, we test at 3 PSI for a minimum 10-minute hold – the standard required by the International Fuel Gas Code (IFGC) as adopted by the PA UCC. Some PECO reconnects, larger systems, or specific township inspectors require higher pressure or longer hold times – we adjust to match what your specific situation requires and document the actual test pressure and duration on the certificate.
How much does a gas line pressure test cost in Chester County?
Pricing depends on system size, accessibility, and whether PECO/inspector coordination is required. We give you a flat-rate written estimate before we begin – no surprise charges. Most standard residential tests fall in a predictable range, and the $149 value of the certificate and coordination is included free with every test. Call (484) 436-4190 for a same-day quote on your specific situation.
What happens if the system fails the test?
We isolate the leak, identify the failed section (corroded pipe, faulty valve, bad connector, missing cap on an old branch), give you a written estimate for the repair, and once approved we repair and re-test the same day in most cases. Because we’re a full-service plumbing and restoration company, we don’t have to refer you out – leak detection, repair, re-test, and any access damage repair all happen with one company.
I have a real estate closing in 48 hours. Can you turn this around?
Yes, same-day and next-day appointments are routinely available for closings, and we can email or upload the certificate directly to your agent, attorney, or transaction portal. If we find a problem during the test, we’ll give you the repair estimate immediately so your timeline doesn’t slip while decisions get made. Call (484) 436-4190 and tell us your closing date – we work backward from it.
Will PECO and Chester County township inspectors accept your certificate?
Yes. Our certificate is signed by a PA-licensed master plumber and includes everything PECO and PA township inspectors require: the system tested, test pressure, hold duration, calibration date of the gauge, result, and the master plumber’s license number. We work with West Chester Borough, West Whiteland, East Goshen, Tredyffrin, Coatesville, and the other Chester County jurisdictions regularly – and we know each one’s preferences.
What Chester County areas do you serve for gas line pressure testing?
We serve all of Chester County including West Chester, Coatesville, Phoenixville, Downingtown, Exton, Malvern, Kennett Square, Paoli, Berwyn, Oxford, and surrounding communities – zip codes 19320, 19335, 19341, 19348, 19355, 19380, 19382, 19425, 19460, and 19464.
