frequently asked questions

What causes foundation damage in Portland homes?

Water is the main culprit. In Portland, heavy rain, poor drainage, and wet soil push water against your foundation. Atomic Construction stops this damage before it starts with waterproofing and drainage solutions tailored to Portland's climate.

How do I know if my crawlspace needs attention in Beaverton?

Signs include musty smells, visible moisture, mold, or soft floor spots. Atomic Construction inspects Beaverton crawlspaces to find problems and fix them with cleanup, vapor barriers, and proper drainage.

What's the first step to fix a wet basement in Gresham?

Call Atomic Construction for a free assessment. We'll identify where water enters your Gresham home and recommend the right fix—whether it's French drains, sump pumps, or downspout systems.

Can you help with seismic safety in Oregon City?

Yes. Seismic retrofitting strengthens older Oregon City homes to meet modern building codes. Atomic Construction handles post and beam installation and foundation reinforcement to protect your home during earthquakes.

How long does foundation waterproofing take in Tigard?

Timeline depends on your Tigard home's size and damage. We'll give you an exact schedule during your free consultation with Atomic Construction so you know what to expect.

What should I do to prepare for a crawlspace project?

Clear access to your crawlspace so our crew can work safely. Atomic Construction will handle the rest—excavation, cleanup, drainage, and vapor barrier installation are all part of our service in Hillsboro and nearby areas.
