"I called Day & Night Plumber again because I had a good experience with their plumber Lal last time. His brother Saul(?) came this time to replace the toilet. As the brother, he explained everything in detail and did the job carefully. There was a little communication problem at the beginning. I called in for a toilet replacement two days earlier and instructed them to come with a specific toilet that I want from Home Depot. I texted the dispatcher the screen shot of the product from Home Depot's website and got her to confirm the job. But the plumber apparently did not get the information so he had to go out to get the toilet which added an extra hour to the job. But overall I like this company. It's small the job quality is consistent. The price is also reasonable. Will hire again for sure."

"We have depended on Fred and Son for expert plumbing help for years now. Today it was Joe who did the installation, and we couldn't be happier with his work. Equally important, we appreciate how friendly, considerate, and professional he was throughout his visit. We will continue to have Fred and Joe on speed dial!"

"We had a great experience with A R Crowell Plumbing! We knew the project of replacing our water main pipe would be expensive, but A R Crowell beat out the competition with their pricing! They even handled all the permits that were needed with the county. The day came and there were complications not originally foreseen, and the entire team handled it well. There was an additional charge for the new work, but that was already stipulated in the signed contract. No hidden fees, no trying to sell us a contract or things we did not need. We will definitely use them again! As a side note, I will say that the communication could improve in some areas, but I will honestly take a fair price with excellent staff and quality work over some slight confusion any day. Thanks to the excellent A.R. Crowell team for their great work!"

"We had a blualator pipeâ the main pipeline running into our home from outside. It began leaking and caused a sinkhole in our front yard. WSSC came out and told us the leak was coming from the pipe on our side not the water company meter. The water company gave me the report with their website for licensed companies. I reviewed it and compared it Angi list and home advisor for reviews. The Waterline Group has excellent reviews. Geary came out to inspect our home. He is professional, friendly, and the gives free quotes. Upon hiring them you will have to make a deposit. The Waterline Group does excellent work and they mark the lines between water and electricity. The Waterline Group beats the other companies by two to three thousand dollars of the other companies I had contacted and the other companies charge a fee to come out. Also, the Waterline Group noticed that when the water would be turned back on it would cause my water heater to leak. They replaced that pipe as well and quoted the price. They guarantee their work in writing. They also make sure that the water company inspector comes out to inspect the work of this magnitude before closing up the hole they have to dig. Once the inspector signs off they close the hole. Also, while the hole is opened warning tape is wrapped around so other people will avoid the area. They also take off their shoes or boots before entering the house. They rinse the porch and sidewalks after they are done with the work and clean up after themselves. I will recommend this company for this type of work every day of the week."

Affordable Plumbers questions, answered by experts

Gaithersburg homeowners can choose from licensed plumbers specializing in emergency repairs, drain cleaning, water heater installation, or bathroom and kitchen remodeling. Some contractors focus on routine maintenance or offer handyman services for minor fixes, while others handle complex commercial plumbing systems. For older homes, look for specialists experienced with local building codes and aging infrastructure to ensure lasting results.

Helpful?

In Gaithersburg, be cautious of quotes that are unusually low, as this may signal inexperience or shortcuts. Avoid plumbers who demand full payment upfront, lack proof of insurance, or provide only verbal estimates. Reliable professionals will offer detailed, written quotes and willingly share local references. Watch for unmarked vehicles, unclear project timelines, or pressure to make quick decisions—these are all warning signs.

Helpful?

In Gaithersburg, emergency plumbing repairs like burst pipes or sewer backups are typically resolved within 2–4 hours, thanks to the availability of 24/7 licensed plumbers. Standard tasks such as faucet repairs or clearing minor clogs usually take 1–3 hours. Larger projects, including water heater installation or whole-house repiping, can span 2 to 7 days, especially if your home requires permits or has older plumbing systems.

Helpful?

In Gaithersburg, schedule plumbing service promptly if you notice leaks, water stains, persistent odors, or inconsistent water temperature. Slow drains, gurgling pipes, or unexplained increases in your water bill also indicate it’s time to call a licensed plumber. Seasonal tasks—like insulating pipes before winter or checking sump pumps in spring—help prevent emergencies and protect your home’s plumbing system.

Helpful?

When hiring a plumbing professional in Gaithersburg, prioritize those with strong local experience, proper licensing, and insurance. Ask for written contracts that outline the scope of work and clarify warranty terms. Choose a plumber familiar with local permit requirements and housing styles, and verify their emergency service availability. Checking recent customer reviews and references can help ensure you select a reputable, reliable expert.
