Aloha Foundation Waterproofing and Leak Repair

What Makes Aloha Homes Wet

Drive the flat blocks off TV Highway and you will notice how little the ground tilts, and that is exactly the trouble: rain here has nowhere to run. Most lots here are level or close to it, so water pools on the surface and soaks straight down beside the house.

What homeowners notice is rarely the water itself. It is a floor that feels cold and slightly springy, a musty smell near the hall vent, or a furnace that seems to run more than it should. Crawl spaces hide the cause, so the first sign is often damage that has been building for several winters.

The homes are mostly one-story ranches and split-levels on crawl spaces, built as the area filled in through the 1960s, 70s and 80s. Full basements are rare. That means the problem tends to appear underneath, where you cannot see it, as standing water under the house, wet soil and damp insulation.

The soil is clay-heavy and slow to drain. With little slope to carry water away and a crawl space that sits lower than the surrounding grade, winter rain can collect under a house and stay there for weeks. An Aloha waterproofing contractor spends most of the job below the floor for exactly that reason.

Winter Groundwater and Your Crawl Space

From October on, a few wet weeks are enough to fill the soil. After that, every new storm adds water the ground cannot take, and on level lots it lies there.

By midwinter, many crawl spaces here have damp soil from wall to wall. Insulation gets heavy and slumps, wood framing picks up moisture, and the air that rises into the home carries that damp smell with it.

Spring brings little relief, because the ground stays wet into April and May. A crawl space that was never drained can stay damp for most of seven months. That is why the work is best done before October: the work goes in dry, and the space stays dry for the whole season.

A crawl space left alone through that stretch is a different job by March. Wet insulation has to be pulled out, and framing that stayed damp may need treatment. Heating ducts run through the same space and sweat all winter, which raises your energy use without any obvious reason.

A site visit covers the crawl space floor, walls and vents, the insulation and framing moisture, the downspouts and gutters, and the grading around the house. If the house has a basement or a daylight section, we look at the walls and floor joint there too. We take photographs so you see what we see.

A short note on what you can check yourself. Open the hatch on a dry day in October and again after a week of rain. Look at the soil, the underside of the insulation and the foot of each foundation wall. Dark, shiny soil or a tide line on the wall means water has been there. If the hatch is in a closet or hallway floor, a cheap moisture meter pressed against the joists tells you whether the framing is drying out or staying wet.

Many owners here also want to know what it will take to fix, not just what is wrong. The honest answer is that the first fix on almost every flat-lot crawl space is drainage and a pump, and the second is sealing. Everything else, including insulation and duct work, is easier and cheaper once those two are in.

Basement and Crawl Space Repairs We Handle Most Here

Because of the flat ground and the number of crawl-space homes, these jobs come up more than any others.

Crawl Space Waterproofing

When water stands under a house, it has to be drained before anything else is done. Drain pipe, gravel and a pump pull the water out and hold the level down through the wet months.

Crawl Space Encapsulation

Once the water is handled, a sealed liner over the floor and walls keeps ground moisture from rising into the home. Our page on crawl space encapsulation in Aloha explains the steps. A heavy crawl space vapor barrier is the lighter choice where the space is otherwise dry.

French Drain Installation

On a flat lot, a French drain gives surface water a path. A sloped, gravel-wrapped drain line collects runoff along the house and sends it out to a place it can safely go, such as the street or a dry well.

Sump Pump Installation

For a crawl space that fills faster than it drains, a pump in a sealed basin is the dependable answer. Sump pump installation turns it on when the water rises and sends it out through a discharge line. Read more on sump pump installation.

The few Aloha homes with basements or daylight sections get different work. A wet basement or leaking basement there usually needs interior drain tile and a sealed sump, with foundation crack repair for any wall that weeps. Our foundation crack repair page explains how injection works.

Around Aloha and Nearby Towns

Our trucks are a common sight throughout Aloha, including streets near 185th Avenue and along Farmington Road, the older subdivisions near Aloha High School, and the blocks south of TV Highway. Lots in the lowest corners of these neighborhoods are the wettest, and they are where we see standing water most often.

The older tracts tend to have original foundation vents, thin or missing ground cover and insulation that has sagged for years. Newer infill homes may be tighter, but they sit on the same slow-draining soil, so they are not immune. Waterproofing services in Aloha therefore start with the crawl space, whatever the age of the house.

Our service area also takes in Beaverton and the Hillsboro side of the highway, where the soil and housing styles are close to what you see here.
