Common Portsmouth Drain Blockages

Different substances create different plumbing issues. Here’s what our technicians typically find in Portsmouth pipes.

Kitchen drains clog as grease cools and hardens inside pipes. Small amounts build up until water barely passes.

Bathroom drains catch hair that binds with soap and styling products, creating dense obstructions.

Only toilet paper dissolves properly. Wipes, tissues, and sanitary items cause stubborn blockages.

A coating of minerals from Portsmouth’s water accumulates inside pipes, narrowing passages and catching debris.

Mature trees throughout Portsmouth send roots into sewer lines through cracks, blocking flow.

Super fast response time (called at 4:00 on Monday and Mike & Chris were at the house at 11:15 on Tuesday). Mike and Chris were excellent, diagnosed the source of the odor (bad wax ring) and completed the job by 12:15.
Everything from the initial phone call to the quick response from our techs and the repair of our system was an A+! Would recommend to everyone.
GEM was one of only services that got back to me and scheduled me on the same day! Colin was quick, professional, and someone I felt safe having in my home. You get what you pay for!

Khorey J. and his colleague did an excellent job inspecting our heating and cooling mini-split system. They took the time to explain the issues in detail and gave us peace of mind and at ease by ensuring that everything was working properly. They also explained and demonstrated when the condenser fan should turn on at various temperatures and settings. Both men were knowledgeable, professional, polite, and respectful. We have been customers of Gem Heating and Plumbing for many years, and, as always, they were there when we needed their services. Thank you, Gem Plumbing!

Have used GEM several times. After some rough experiences with some other HVAC companies, I can say GEM has been consistently outstanding. Highly recommended.
We had an emergency service performed on Saturday, the technician Chris was professional and talked me through everything he was doing. I’d rate his overall work on a scale of 1-10 as over 10 because he was that awesome. What gets me is the pricing of the service. As I mentioned it was an emergency, and as the customer I want an itemized breakdown of parts and labor. I just called GEM and they mentioned they do not provide that. I will continue to call until I get the satisfaction I want on full disclosure of MY billing statement the was paid for in FULL by MYSELF. I know GEM reads these reviews and I want my fully itemized bill for services rendered.
Very satisfied with the service

Professional Clearing vs. Chemical Products

Store-bought drain cleaners promise quick solutions but typically cause worse problems.

Chemical products corrode pipes while only partially clearing clogs. Here’s why professional service is smarter.

Store chemicals eat away pipe walls, especially older Portsmouth systems. Professional methods protect all materials.

Retail products dissolve just enough for water to trickle. Professional tools remove everything so clogs don’t return quickly.

Professional plumbers determine why blockages form and suggest prevention. Chemicals only mask symptoms.

Drain cleaners emit toxic fumes and leave residue. Professional techniques eliminate these hazards.
