Water Damage Repair You Can Depend On

Protective Deck Sealants

The wet Pacific Northwest weather causes havoc on untreated decks. Seattle Deck Waterproofing located in North Seattle, knows the importance of protecting your deck with the best waterproofing products. We know that using the right deck sealants is the secret to a lasting, beautiful deck.

What You Should Know

The most effective waterproofed decks use sealers filled with flexible membranes that keep in water. Over time, exposure to harsh weather, sunlight, and foot-traffic diminishes the flexibility of these vital membranes, allowing water to escape. Our crew applies a fluid coating system to waterproof your promenade deck, balcony, sun deck, and parking deck. This provides seamless and most desirable results with the highest amount of protection possible.

Coating & Sealing Benefits

Our application experts coat the surfaces of your deck with industry-leading waterproofing solutions, sealants, and finishes. Once applied, you'll feel confident knowing your structure has superior UV protection and the concrete won't deteriorate or scale.

When & Why to Take Action

To maintain the look of your deck, we recommend waterproofing every 7 to 10 years. Of course, doing it more frequently provides even greater protection, for example, in salt-water marine settings. If neglected for any further amount of time, you may experience additional damage and deterioration, resulting in expensive repairs along with new waterproofing.

Total Rot Remediation

Almost all timber will deteriorate when exposed to moisture for long periods of time. Fungal decay or rot is the result. There are three broad categories of rot – brown rots, white rots and soft rots.

Brown rots eventually darken the appearance of the timber as they consume only cellulose, leaving behind the darker woody lignin. Decayed timber may still look satisfactory but can be readily penetrated by a knife. Brown rots are considered to be more severe than other types of rots. This is because they decay timber more rapidly, and once started, they tend to operate at lower moisture levels than other rots. One particularly malignant brown rot is Serpula lacrymans, commonly known as "dry rot". It derives its name and reputation because of its ability to transport moisture, enabling it to attack otherwise dry timber.

White rots appear to bleach the timber, giving decayed timber a yellow-white fibrous appearance. The coloration is because they consume both the lignin and the cellulose. White rots commonly operate at mid to higher moisture levels.

Timber infected by soft rots often shows little outward sign of decay. The only sign is that the timber may have darkened or appear to be grayish. In advanced stages of soft rot decay, the timber can easily be carved with a sharp knife. Soft rots are usually found on timber in contact with the ground as they tend to need elevated moisture levels to grow.

Simply put, rot remediation means to repair or replace the existing rotted wood, a potentially complex job. That's not a worry when you call us, as we have the skill needed to give you the best results and bring your deck back to life, no matter what the extent of the damage.
