"These guys were great, and the owner, Jo Estrada, a pleasure to work with. A crew of 5 spent 5 hours cleaning, inspecting, and replacing insulation and vapor shield in our crawl space. They took pictures of everything, before and after. THe crew was pleasant, and worked really hard.... couldn't believe how much stuff they removed from under there. The crawl space is tight, but they didn't complain (at least to us!). They gave us good recommendations for some repairs needed for the foundation. All for a most reasonable price, compared to other estimates. They deserve every star they can get!"

"Had a great experience with WA Evergreen Insulation from start to end. Rob came to my house, quoted me an insulation install, made absolutely sure that they would not cover any existing knob and tube with insulation and prevent a fire. The crew showed up and completed the job in one day. Once they got started it was clear they knew exactly what they were doing - and they managed to shimmy into the extremely small attic access and cleaned up my rat jerky in the crawlspace! I'm very happy with this job and with this company!"

"G&S did an excellent job installing our new furnace and AC unit. The best thing about G&S is that they warranty for 1 year. The circuit board in our furnace failed within a couple of months (no fault of G&S). Manufacturers warranty would cover the parts cost but G&S repaired and covered labor cost under their warranty. Also they diagnosed the issue and repaired very quickly. Definitely A++ installation and service."

FAQs for sump pump or interior foundation drains installation projects in Granite Falls, WA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
