Home » Grafton

Grafton’s mix of established neighborhoods and newer residential development means home systems can differ considerably across the community. An older house may have aging plumbing or heating equipment that has been updated over time, while newer homes can have different comfort concerns related to larger floor plans, finished basements, or changing household demands.

Southport Plumbing, Heating & Cooling serves Grafton through our Southeast Wisconsin service area. We handle furnace repair, AC repair, plumbing problems, drain cleaning, sump pumps, water heater repair, garbage disposals, and other heating and cooling needs.

Schedule HVAC or plumbing services for your Grafton home today.

Heating & Cooling

Winter around Grafton puts heating equipment through months of regular use. Furnaces and boilers need to keep pace when temperatures remain below freezing, and problems such as short cycling, weak airflow, unusual sounds, or cold rooms can become much more noticeable during a prolonged cold spell.

Summer changes the workload. Heat and humidity put central air conditioners back into regular operation, while upper floors, additions, and finished spaces can sometimes be harder to keep comfortable than the rest of the house.

Book heating or cooling service when your Grafton home’s comfort starts changing.

Plumbing

Cold weather can expose vulnerable plumbing in Grafton homes, especially pipes running through exterior walls, garages, or other areas where temperatures can drop. Once winter gives way to thawing ground and spring rain, sump pumps and basement drainage can become a bigger concern.

Other plumbing problems develop regardless of the season. Slow drains can become recurring clogs, an aging water heater may struggle with normal household demand, and leaking fixtures or garbage disposal problems can make everyday routines more difficult.

  • Leaks, fixture problems, sump pumps, garbage disposals, and other household concerns can be handled through our plumbing services.
  • Drains that repeatedly clog or empty slowly may need professional drain cleaning to address the cause.
  • Reduced hot water, fluctuating temperatures, equipment noises, or moisture around the unit may indicate a need for water heater service.

Schedule plumbing service when a drain, sump pump, water heater, or other plumbing problem starts disrupting your Grafton home.

Thank You Riley and Southport Plumbing for a quick response to a very clogged toilet.
Riley arrived within minutes of the scheduled appointment and completed the work quickly and efficiently. He answered all my curious questions politely and cleaned the area completely after the work.
Lesson learned… don’t dump your cleaning water down the toilet with the sponges and rags you used!!!

I had a boiler system installed by Southport and everyone I interacted with was fantastic! After several quotes I selected them because I thought the company had a lot of integrity. I first got a quote from Caleb who was most professional, walking me through all the options they had for me and being very reasonable on the pricing. They scheduled the installation within a week and, on that day, the technicians Ryan and Jacob were excellent and very hard workers. I appreciated that they were very careful inside the house, putting shoe protectors while upstairs and overall being very respectful. They stayed until the job was done and my heat was restored. I would highly recommend Southport if you need a new boiler installation or and work or maintenance on your boiler, home heat, or water heating system.

Thank you for sending Andrew Wenk to test our furnace. He could answer our questions clearly and tested all the important components and measured various pressures, temperatures, speeds, and other technical factors. He gave us 3 estimates for replacing parts that are needed due to age of the furnace. Andrew was pleasant and respectful to us.
