Portland Mold Removal

Why Choose SFW For Mold Removal?

An introduction of moisture is essential for mold growth. SFW Construction is the Pacific Northwest leader in waterproofing and moisture control. Most mold issues in Portland stem from water passing through your home’s building envelope, siding, and roofing system into your home’s warm conditioned spaces. The first signs of an issue might be exterior dry rot.

We Offer A Lasting Solution

Other companies may be able to remove the mold, but they will not be able to offer a lasting solution to ensure the problem does not reoccur. That’s why SFW Construction is the clear choice for mold testing and removal in Portland. Eliminating the mold colony is just the first step. Tracing the root cause of the moisture intrusion and rectifying the waterproofing defects to ensure the issue is solved is critical.

Mold Testing And Inspections

Mold is a fungus that grows in the form of multicellular filaments called hyphae. For mold to grow, a moist environment is needed. The climate in the Pacific Northwest is ideal for cultivating mold colonies. Visible signs of mold don’t require much regarding testing or inspection. Portland homeowners and commercial building owners trust the professionals at SFW Construction to inspect your home for moisture intrusion points that are the genesis of the issue.

Do You Constantly Feel Sick Or Have Severe Allergies?

If your family is getting sick repeatedly, or you have severe allergies, you may have a non-visible mold colony. With our advanced testing equipment and industry knowledge of waterproofing defects, we can locate areas of your home where mold is an issue.

Why Fogging With Biocides Or Demolition Free Remediation Is Not Recommended

Biohazard

There is no quick fix, or labor free, final solution to mold removal.

Some companies advertise “demolition free” or fogging with biocides for mold removal. SFW Construction does not recommend the use of gaseous, vapor-phase, or aerosolized biocides for mold remediation. These products can pose health concerns to homeowners and pets.

The effectiveness of these methods has yet to be proven 100% effective and does not ensure environmental health issues from remaining non-viable mold spores.

Other companies push this method because it is very profitable and non-labor intensive. Homeowners like the idea of non-invasive or destructive methods but unfortunately, they just aren’t effective. The money you save on the initial remediation won’t compare to a second trip to do things right.

What Does The Environmental Protection Agency Say About Mold Remediation And Clean-up?

EPA ‐ Mold Remediation/Cleanup and Biocides

The purpose of mold remediation is to remove the mold to prevent human exposure and damage to building materials and furnishings. It is necessary to clean up mold contamination, not just to kill the mold. Dead mold is still allergenic, and some dead molds are potentially toxic. The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation.

With traditional methods of mold remediation, it is not possible or desirable to completely sterilize an area; a background level of mold spores will remain in the air (roughly equivalent to or lower than the level in outside air).

Traditional disinfectants or biocides require that the area is always ventilated. Outdoor air may need to be brought in with fans. However, fans can potentially distribute mold spores throughout an unaffected area. In addition, understand that biocides are toxic to humans, as well as to mold.

Questions About Dry Rot?

Dry Rot Repair FAQs

Can Dry Rot Be Covered, Or Just Painted Over?2026-03-19T10:43:11-07:00

No, dry rot can not be covered up or painted over it will continue to grow and eat at the affected areas until it is cut out and removed.

I Have Dry Rot Under My Siding; Why Will No One Give Me A Firm Bid?2026-03-19T10:53:47-07:00

This is a common question we get when it comes to hidden dry rot damage as dry can be under your siding without you knowing. Since dry rot can travel, there is no way to see the damage’s extent without opening the material up and seeing what is under the siding. I would be wary of any contractor who appears the know the extent of the affected area just by looking at the outer material only. There are many factors to how dry rot spreads, amount of time, moisture levels, type of product affected, how the area was constructed, building defects, and animal damage. So, with all these factors to make a proper diagnosis, the affected areas need to be inspected and seen.

If You Discover Dry Rot, What Do You Do?2026-03-19T10:55:36-07:00

If you discover dry rot our recommendation would be to find a contractor that is experienced and knowledgeable in dry rot repair, someone who can resolve all your dry rot issues and eliminate the problem from the source. Your contractor should understand the skill, care, and work needed to inspect, locate, and effectively remove and remediate moisture along with making the necessary repairs caused by dry rot. If you do not want the structural support of your property at risk, do your research before hiring a contractor.

What Is A Targeted Dry Rot Repair?2026-03-19T11:01:14-07:00

A targeted dry rot repair is cutting out the damaged areas and conducting a small repair. After we tye the repaired area back into the existing material. This method saves homeowners time and money. Many contractors will recommend extensive repair, or guess how much damage is behind your siding when just a small space is affected, so they can secure a long, unnecessary, and profitable project at the homeowner’s expense.

What is Dry Rot?2026-03-19T11:01:48-07:00

Dry rot is the leading cause of damage in wood structures in the Pacific Northwest. Dry rot, which is sometimes called brown rot, wood rot, and wet rot, can lead to even more mold and mildew issues. This makes dry rot challenging to spot before it spreading—and nearly impossible to predict. As the fungi spread, they eat away at the wood, leaving it dark and crumbly. At that point, you can even crush the wood into small chips or powder with your bare hand. Unfortunately, once dry rot begins spreading within a structure, it doesn’t stop.
