PAST CLIENT REVIEWS
"My first call for any home service! They have fixed my sump pump , serviced my gas fireplace and other plumbing jobs around the house . I love that they are local and despite being so efficiently run with every little detail (including a text with a picture letting you know that their technician is arriving shortly) their service technicians and phone customer service reps are the best and really take the time to discuss and explain the issue."
Maureen C.
"I had the pleasure of contracting Donaldson HVAC to do some plumbing work for me and was quite pleased with the knowledge and experience of Liam. Prior to the job, Rob gave me a thorough session of questions which lead to a reasonable quote the same day. If I need more Plumbing work, I will definitely contract Donaldson again."
Rick M.
"I had a back up sump pump jet system added. I can’t believe how it turned out, Amazing! I have a friend who is a plumber for 15 years and sorry my friend. His work is nothing like this!. These guys are so professional, and their work speaks for it self. I would totally recommend this company."

FREQUENTLY ASKED QUESTIONS
Our April sump pump sale gives homeowners the best price of the year on a new Liberty sump pump and battery backup system. This combo provides full basement flood protection, especially during spring storms when power outages are common. Buying now means maximum savings and immediate protection before heavy rain hits.
A battery backup sump pump keeps your basement protected even when the main pump loses power or becomes overwhelmed. During storms, outages, or pump failures, the backup automatically activates to prevent flooding. It’s one of the most reliable ways to avoid costly water damage and ensure 24/7 sump pump performance.
We offer fast, professional sump pump installation, typically completed in 2–3 hours. Our team installs both pumps in one visit, tests the system, and ensures your home is protected right away. Booking during April ensures you’re ready for peak rainfall season.
Yes. The primary sump pump handles everyday water flow, while the battery backup sump pump activates during power outages or high‑volume storms. Together, they provide continuous basement flood protection, keeping your home safe throughout the rainy season and beyond.
Yes, there is a 3-year manufacturer warranty.
