Streamline Services, Inc. has been serving the plumbing, electrical and HVAC needs of Raleigh and surrounding areas for over 20 years. We offer 24/7 support and fast, same day repairs. We are a family-owned and operated business. We're committed to providing the highest quality service with our licensed and certified technicians, continuing training, and dedication to our community. Our core values are simple yet impact the way we go about our day – dependable, dedicated, positive, eager to learn, process-driven, and humble. The relationships we cultivate and develop amongst ourselves and with customers is something we pride ourselves with every day.

"I used Streamline Services to replace my HVAC system and to install insulation on the ductwork in my basement in August 2024, and unfortunately that was an extremely expensive mistake. We have since had them out 7 times that I have record of to repair issues related to the ductwork insulation, at extreme disruption to mine and my husband’s jobs which are based in our home, and on 2 of those occasions they also had a manager supervising. It’s the least of my concerns at this point but they left a mess each time they came, insulation scraps and screws all over the place and tape stuck to the floor. After all that, the insulation has never been properly adhered to the ductwork and has fallen down repeatedly, there are multiple areas all over our basement where the fiberglass insulation is exposed and where the tape has visibly lifted and the insulation is just resting on top of the duct. Their communication is somehow even worse than their workmanship. I’ve been trying to speak to a manager about a refund since December (I have record of 10 such inquiries I made in that time) and I’ve either been ignored or told that someone will call me and it never happens. They did give me a refund that amounted to roughly 8% of what I paid for the duct wrapping about two weeks ago, without contacting me or letting me know which I found odd, however that is not at all reflective of what I should be refunded after all of this and I think they just did it in hopes that I would leave them alone. I really wanted to resolve this with them amicably and have been exceedingly patient with them but unfortunately that goodwill hasn’t been reciprocated. We paid for our ducts to be wrapped and sealed and I think it’s clear we didn’t get what we paid for."

"They claimed it was a week long job, but then came in and did the work in one day. I paid over $400/hr for the work they did. They claimed to do the work with the proper permits, but they didn.t I was left holding the bag, trying to get the work permitted after they did the work. The work has been sitting there for about a month as I try to get the work inspected and get this nightmare behind me. I am so naive and trusting. Never again. I would never recommend William Parish Plumbing, quite the contrary"

Septic tank services FAQs

Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.

The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.

A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.

Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
