Editorial Review
Our Take on Guaranteed Plumbing & Heating
The combination of sewer excavation, curb trap work and full HVAC under one roof is genuinely useful in a city where those problems arrive together, and a 4.8 average across 910 Google reviews suggests the delivery mostly matches the promise. We would press on the specifics before signing: what the free estimate includes, after-hours rates, and exactly what the guarantee covers in writing. Homeowners outside the Northeast and the Montgomery and Bucks corridor should confirm coverage first.
Best for: Northeast Philadelphia homeowners needing sewer, curb trap or heating work from one contractor
What We Like
- Plumbing, sewer and HVAC handled by the same company, so fewer separate contractors to coordinate
- 4.8 rating from 910 reviews on its Google Business Profile, read September 26, 2026
- Published hours list 24 hours a day, seven days a week, with same-day service promoted on its site
- Sewer line, curb trap and excavation capability that smaller shops often subcontract
- Trading since 1990 as a family-owned business, per its own website
- Lists plumbing code violation corrections and insurance claim work, useful after a failed L&I inspection
Things to Consider
- Licensed Master Plumber and BBB accreditation are the company's own claims, so ask for the licence number
- Named service areas lean toward Northeast Philadelphia and the Montgomery and Bucks suburbs, so confirm coverage elsewhere
- Free estimates are advertised, but diagnostic and after-hours charges are not published and should be confirmed by phone
- No pricing is published, so get a written quote before work starts on excavation or system replacement

About Guaranteed Plumbing & Heating
Philadelphia housing stock punishes plumbers. Rowhomes from the 1920s with cast iron stacks, clay laterals under the sidewalk, curb traps that nobody has looked at in fifty years, and heating systems that range from steam boilers older than the occupants to newer high efficiency furnaces shoved into tight basements. A company that handles only fixtures and faucets will hand half of that off to someone else. Guaranteed Plumbing & Heating is set up to take the whole spread, and its published service list reflects that: emergency plumbing repair, leak and ceiling leak work, repiping, gas lines, water lines, excavation, sewer line repair and replacement, curb trap repair, drain cleaning, hydro jetting, camera inspections, sump pumps, sewage ejector pumps, water heaters, boilers, furnaces, heat pumps and air conditioning.
The firm describes itself as family owned and operated since 1990, working out of 900 Cottman Ave in the Northeast, with coverage into Bucks and Montgomery counties. It claims a licensed Master Plumber and BBB accreditation. Those are the company's own statements rather than things verified here, and a licence number is worth asking for on the phone, as you would with any contractor doing gas or sewer work in the city. On the review side the picture is clearer: the Google Business Profile carried a 4.8 rating from 910 reviews when it was read on September 26, 2026. Nine hundred plus reviews at that average is a lot of completed jobs and a fairly consistent experience behind them.
Who it suits. Homeowners in the Northeast and the inner suburbs who want a single number for both the wet trades and the mechanical ones, and who would rather not coordinate a plumber, a drain specialist and an HVAC company across three separate visits. Anyone facing a sewer lateral or curb trap problem should find the excavation and camera capability useful, since that is the kind of job many smaller shops subcontract. The listed code violation and insurance claim services also point toward people dealing with a failed inspection, a property sale, or a water damage claim where paperwork matters as much as the repair.
Who it suits less well. If you want a ground-up bathroom gut with tile, carpentry and design, a full remodeling contractor is probably a better fit, although bathroom remodeling does appear on the service list. Landlords hunting the absolute cheapest hourly rate may find a larger staffed operation with 24 hour dispatch is not the lowest bidder on a simple washer replacement. And the published service areas lean north and northwest, so households in South Philadelphia, West Philadelphia or Delaware County should confirm coverage before booking.
How the day-to-day appears to run. Hours are published as open 24 hours, every day, and the site promotes same-day service, free estimates, coupons and financing with instant approval. Treat the free estimate language carefully and ask what it covers. In this trade an estimate on a replacement, say a water heater or a furnace, is usually free, while diagnosing why an existing system has failed often carries a service or trip charge. Get that distinction in plain language before the van is dispatched, along with whether the after-hours rate differs from the weekday rate.
Questions worth asking. Who pulls the permit for gas line, water service or sewer work, and is the city inspection included in the quoted price. For a lateral or curb trap job, will you get the camera footage. On heating and cooling replacements, what is the manufacturer warranty on the equipment, what separate labour warranty covers the installation, and is the installer factory trained on that brand. For repiping, ask whether the bid is copper or PEX and how many walls come open. And ask about the guarantee implied by the company name, specifically what is warranted, for how long, and in writing.
Compared with the alternatives, the Philadelphia market splits between one-van operators who are often excellent and often booked, and national franchise brands with slick scheduling and higher tickets. A long-running local company with several hundred reviews and combined plumbing and HVAC departments sits between those poles. If you want overnight availability and someone who has seen Northeast Philly basements before, guaranteed plumbing heating is a reasonable shortlist candidate. Compare guaranteed plumbing heating against at least one other bid on any job over a few thousand dollars, because excavation and system replacement pricing varies widely across the city.

Guaranteed Plumbing & Heating FAQs
Does Guaranteed Plumbing & Heating work at night and on weekends?
Published hours list the business as open 24 hours a day, seven days a week, and its site promotes emergency plumbing and emergency HVAC service. After-hours rates are not published, so ask on the call whether a night, weekend or holiday visit is billed differently from a weekday appointment.
What areas does it cover?
Philadelphia plus Bucks and Montgomery counties, according to its own website. Named areas include Northeast Philadelphia, Mayfair, Fox Chase, Torresdale, Abington and Glenside. The office is at 900 Cottman Ave in the Northeast, so households further south or west should confirm coverage before booking.
How is it rated?
Its Google Business Profile showed 4.8 from 910 reviews when read on September 26, 2026. That is a large review count for a single-location contractor, which makes the average more meaningful than a handful of scores would be.
Can it handle a curb trap or sewer lateral in an older rowhome?
Yes, curb trap repair and replacement, sewer line repair and replacement, camera line inspections and excavation all appear on its service list. For that kind of job, ask who pulls the city permit, whether street or sidewalk restoration is included in the price, and request the camera footage so you can see the defect yourself.
Does it do heating and cooling as well as plumbing?
It does. Boiler repair and replacement, furnace repair and replacement, heat pumps, AC repair and replacement and emergency HVAC work are all listed alongside the plumbing side. Using guaranteed plumbing heating for both trades can save a second contractor visit when a basement problem turns out to involve the boiler as well as the drain.
Are estimates free, and is financing available?
The website advertises free estimates, coupons and financing with instant approval. In this trade a free estimate usually applies to replacement quotes rather than diagnosing an existing fault, so clarify which applies to your job and whether any trip or diagnostic fee is charged if you decline the work.
How long has the company been trading?
Since 1990, according to its own website, as a family owned and operated business. It also states it holds a licensed Master Plumber credential and BBB accreditation. Those are company claims rather than details verified here, so ask for the licence number when you book gas, water service or sewer work.
Is Guaranteed Plumbing & Heating licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does Guaranteed Plumbing & Heating serve?
Philadelphia, Cheltenham. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Guaranteed Plumbing & Heating offer emergency service?
Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
Can a business pay to improve its profile?
