Bathroom Plumbing Services

Do you know why it’s so important to hire a trained and experienced plumber for your bathroom plumbing services? First off, if you’re investing in a bathroom plumbing installation or remodel, you want to make sure that everything is done correctly. A properly sized toilet will prevent unhygienic leaks, and a properly sloped shower floor will prevent standing water and mold growth, for example.

We’re your trusted team for all your bathroom plumbing services whether it’s a tub installation, sink repair, or even a complete bathroom remodel. We install and service toilets, bathtubs, and showers! Contact us today to learn more.


Bathroom Plumbing Repair

The best way to prevent the worst and most urgent of bathroom plumbing repairs is with comprehensive bathroom plumbing maintenance. Ask about our Silver Shield Preferred Membership or Gold Shield Preferred Membership! These are our maintenance programs that include an option for a bathroom maintenance plan. Thorough maintenance and drain cleaning will help keep all your plumbing components in great shape.

Of course, when you do need repairs, we’re the team to call. Reach out to use for toilet repair, toilet replacement, tub repairs, tub drain repair, and more!


Kitchen Plumbing Installation

Even the savviest of Bellingham area homeowners may not realize just how much goes into a fully functional and efficiently operating kitchen. Not only do we offer the services you’d expect such as installing garbage disposal units, repairing kitchen sinks, and performing kitchen plumbing replacement, we’re also a leading provider of instant hot water dispensers for kitchen faucets so you can effectively clean and sanitize cooking tools and more.

Of course, when you do need something like an effective garbage disposal installation or a new kitchen sink, we’re the team to trust. We’ll manage your kitchen remodel and plumbing fixture placement, too!


Kitchen Plumbing Repair

Kitchen plumbing maintenance through our Silver Shield or Gold Shield Preferred Membership is the best way for you to keep your kitchen plumbing fixtures and appliances in great shape. But when you do need repair, we’re here for you 24/7. You just might need that kind of availability when you have a kitchen plumbing emergency like a clogged up garbage disposal or a backed-up kitchen sink.

We’re your leading Bellingham plumber for faucet repair, faucet replacement, sink repair, and more! Schedule an appointment or give our number a call today.



Plumbers, Electricians, HVAC Technicians, these jobs are in demand right now—big time. For every 5 retiring, just one is entering the trades. As we come into a new decade, it’s time to change the definition of “success” and how to achieve it.

My Grandpa Dan founded Barron nearly fifty years ago with the goal to provide our community with quality service while supporting his employees with exceptional careers. To carry on his legacy, we’re on a mission to prove that a career in the skilled trades is a rewarding one.

In his honor, the Barron Team has created the Dan L. Barron Trades Scholarship, which will provide opportunities to individuals looking to enter the HVAC, Electrical or Plumbing trades.

Barron will provide two $5,000 scholarships to Bellingham Technical College: one to a current Barron employee or family member, and one to a community member.

Q Will a bigger filter help?

Your home’s HVAC system is equipped with a system filter that uses a MERV rating system. While standard filtration (typically a MERV 11 filter) does contribute to indoor air quality, it is important to note it is designed to protect the equipment. So, does upsizing or increasing the MERV rating of a filter help? The short answer is yes, but there is a very possible negative impact, too. Higher MERV rated filters can significantly increase the static pressure of your home’s duct system. Static pressure is like the blood pressure of your home’s HVAC system. Static pressure that is too high is actually the number one cause of equipment failure. So attempting to increase the size of the filter without taking into account the entire system can potentially lead to equipment failure.

Q How can I check the static pressure of my home?

A Barron Home Performance Expert can test the static pressure of your duct system to determine what’s necessary to increase filtration. Contact us today to schedule a Home Performance Assessment.

Q Should I run my fan all the time (on

The answer is yes, but only IF you have a sealed duct system.

If you have a sealed duct system, great! You can run the constant fan. To set the fan to constant fan mode, please refer to your thermostat / HVAC systems user manuals.

That said, EPA experts have found that most existing duct systems leak between 20-45% or more. If your duct system is leaky like most systems, the reality is you can actually create a negative air pressure situation in your home which means you can bring in a significant amount of unwanted outside air (see our video on Home Performance) Negative air pressure situations increase "infiltration". For more about duct sealing and the unique Aeroseal process, please read here. Aeroseal is our number one requested service. And remember, with all of our services we guarantee 100% satisfaction.

Note: if you have a fresh air intake on your HVAC system, be sure to close the damper before running the fan.

Q Are there other types of filtration with less impact on static pressure?

Yes. Electronic air cleaners (often referred to as EACs) filter the air by positively charging particles as they move through the unit. The particles are then captured by negatively charged collector plates. This process allows them to have much less impact on static pressure.

Q Do ionizers or air purifiers help protect my indoor air quality?

Yes, air purifiers like the REME HALO or HALO LED can assist in IAQ in several ways.
Using ultra-violet light to eradicate pollutants, air scrubbers also produce hydro-peroxide plasma to purify the air inside your home. The charged plasma causes particles to stick together, making them larger and easier for filters to catch.

Q What is the best filter option?

Again, taking the specifics of your home into account is critical. Once you’ve done that, you can explore several solutions that do include higher MERV filtration, HEPA bypass filters, air purifiers, EACs, Aeroseal® for duct sealing, and whole-home sealing.

Q Is there a whole-home approach to IAQ?

Yes. We call it the Ultimate IAQ package.

Q I have a

Good news! With a ductless heat pump you are already halfway to better air quality. As we’ve noted already, leaky ducts are a major cause of negative pressure and infiltration (unwanted outside air being pulled inside the home). Homes that use Ductless already have eliminated the ductwork – and do not have leaky ducts to contend with. You’re halfway there! The other considerations are the overall air envelope of the home (which you can test with a Home Performance Assessment), and point-of-use air purifiers like the RGF Clear Sky MS and Mini Split PHI Air Purification system.
