Encapsulation

Protect Your Home with Professional Crawl Space Encapsulation

Encapsulations help in providing a permanent solution to any number of destructive things caused by moisture, dampness, and neglect. We are happy to provide crawl space encapsulation in Portland, Eugene, Vancouver WA and surrounding areas.

A standard vapor barrier often isn’t enough to handle the 40+ inches of annual rainfall we see in Oregon. Encapsulation goes further, transforming your dark, damp crawl space into a clean, dry, and controlled environment.

The Better Basements Encapsulation Process

01

Inspection & Prep

We begin with a thorough assessment of your crawl space. We remove old, sodden insulation and debris that can harbor pests and odors.

02

Water Management

If your home has active standing water, we install a sump pump system and interior drainage to ensure moisture is redirected away from your foundation before the sealing begins.

03

The Seal (Encapsulation)

We install a heavy-duty, reinforced vapor barrier across the floor. We extend this barrier up the foundation walls and seal every seam with industrial grade waterproof tape.

04

Insulation

To control temperature we then spray foam all foundation walls and rim joist. Some opt to have their floor joist insulated as an extra layer of warmth to your floors.

05

Air & Vent Sealing

To prevent humid Oregon air from entering, we seal off crawl space vents. This stabilizes the temperature under your home and protects your floor joists from rot. We can now install a dehumidifier to maintain the exact moisture level.

Questions & Answers

Basement Waterproofing FAQs

That is a loaded question. Most crawl space waterpoofers would not hesitate to tell you every home needs to be encapsulated and anything else is wrong and a disservice. We see the value in them and think they are great.

However, what you “need” is entirely subjective on budget, goals, and values. Do you need one? Possibly, but not likely. Do you need to waterproof? In Oregon, it is very likely.

An encapsulated crawl space is able to manage the humidity at 50% because we install a dehumidifier and spray foam the stem walls.

There are tons of claims out there about it helping with indoor air quality to help regulate asthma and allergies. These are big claims that we do not promote. What we do know is this is an excellent solution for many homeowners trying to manage mold, fungus, and other rot issues!

The main reason people do not encapsulate is because of the cost. These can range from $10,000 – $50,000. There are a ton of factors in projects these large. The better question is, do I see the value at the price point? And, how much more is it than solving my problem with a vented crawl space? These are questions that we can’t answer for you but are happy to guide you through and deliver your selection.

Usually a vented crawl space waterproofing system as soon as you know it will do the trick. But the typical exterior care on gutter and down spout maintenance is key for any long term success in protecting your home and its foundation.
