Sump Pump Installation

When it’s time for a new sump pump, we handle every step—from removing the old unit to installing a properly sized, high-quality replacement. Our team ensures your new system is securely set in the sump pit, connected to an effective drainage line, and tested for optimal performance. We also offer battery backup systems that activate automatically during power outages, giving your home an extra layer of protection. Every installation is done to code, with attention to detail and long-term reliability in mind.

Call our sump pump experts at (406) 481-3548 for professional replacement or new installation—done right the first time, with reliable protection you can count on.

Battery Backup Systems for Storm Protection

A sump pump is only useful if it has power—and in Montana, the worst storms often knock that out. That’s why we strongly recommend adding a battery backup system to your sump pump.

Battery backups automatically kick in when your main pump loses power, giving you peace of mind that your basement or crawlspace stays dry even during outages.

Benefits of a backup system:

  • Keeps your sump pump running during power failures
  • Provides protection during heavy rains and storms
  • Automatically charges when not in use
  • Helps avoid costly flood damage

We install high-quality, reliable backup systems that integrate with your sump pump setup. Our technicians will walk you through your options and make sure your system is ready for anything.

Add extra protection to your home—ask us about battery backup installation when scheduling your sump pump service.

What to Expect: Sump Pump Costs & Timeline

How long does sump pump installation take?
A standard sump pump installation in Missoula typically takes 3–4 hours. If we’re replacing an existing unit, it’s often completed even faster. More complex installs, like adding a new pit or battery backup, may take longer but are usually finished the same day.

How long does sump pump repair take?
Most sump pump repairs can be completed in 1–2 hours, depending on the issue. Common fixes like float switch replacements or unclogging discharge lines are quick. Motor or electrical repairs may take longer, but our trucks are stocked with parts to minimize delays.

How much does sump pump service cost in Missoula?
Costs vary depending on whether you need a repair, replacement, or new installation. Repairs are generally more affordable and can restore function quickly. Full installations cost more upfront but provide reliable long-term protection. We provide upfront estimates so you’ll know the price before work begins, and we’ll walk you through whether repair or replacement makes the most sense for your home.

Common Sump Pump Problems We Repair

Float switch failures are one of the most common causes of sump pump issues. If the float switch gets stuck or misaligned, the pump won’t activate when water rises, leaving your basement vulnerable to flooding.

Power or wiring issues can prevent the unit from turning on at all. In some cases, a tripped breaker or faulty outlet is to blame—but more serious problems can involve motor failure or electrical shorts inside the pump housing.

Worn-out motors or clogged impellers reduce the pump’s ability to move water efficiently. You might hear strange noises, notice slow drainage, or see standing water in the pit—signs that internal components need repair or replacement.

Improper drainage from the sump pit can result from a poorly installed or damaged discharge line. If water is backing up or draining slowly, the line may be frozen, clogged, or incorrectly sloped.

Frozen or blocked discharge pipes are especially common in colder seasons. When water can’t exit the system properly, it puts pressure on the pump, increasing the risk of burnout or backup.

At Garden City Plumbing, we diagnose these issues quickly and provide durable, code-compliant repairs that restore full function to your sump pump. If your system is older or beyond repair, we’ll help you plan a replacement with better long-term performance.

Frequently Asked Questions About Sump Pumps in Missoula

How long does a sump pump last in Montana?
Most sump pumps last 7–10 years in Missoula’s climate. Heavy spring runoff and frequent cycling during wet seasons can shorten that lifespan if maintenance is skipped. Regular inspections and timely repairs help extend the life of your pump and avoid unexpected failures.

How do I know if my sump pump is failing?
Warning signs include loud or unusual noises, constant cycling even when water levels are low, slow pumping, or standing water left in the pit. If your pump runs but doesn’t move water efficiently, it may need repair or replacement.

What size sump pump do I need for my home?
The right pump depends on your basement size, water table, and discharge line setup. Most Missoula homes do well with a 1/3 or 1/2 horsepower pump, but homes in flood-prone or high-groundwater areas may need a higher-capacity model. Our plumbers calculate the correct sizing so your system doesn’t overwork or fall short during heavy rains.

Do sump pumps need maintenance?
Yes. Annual maintenance helps prevent float switch failures, clogged impellers, and motor burnout. We recommend a full inspection before spring melt to make sure your pump can handle seasonal runoff.
