Posted on Bo MaisanoTrustindex verifies that the original source of the review is Google. Raman and his team did a wonderful job replacing our deck. Alex and his guys powered through the cold, rain and darkness with a wonderful outcome. They were able to add on storage box and close under the stairwell with no problem and wonderful results. We appreciate the effort, communication and thoughtfulness.Thank youPosted on mark oTrustindex verifies that the original source of the review is Google. I was extremely happy with the work Intercrus did on our project. We replaced our aging deck with composite decking, added a cable railing system, and also had our fence replaced. The entire process was excellent from start to finish — from the initial bid through construction, the team was easy to work with, fairly priced, and worked incredibly hard to get the job done quickly. The final deck and fence turned out beautifully, and I would highly recommend IntercrusPosted on Robert O’TwomneyTrustindex verifies that the original source of the review is Google. Raman and team did a series of medium-sized sorely needed projects for us, including new rooftop deck with corrected slope and waterproofing, new tongue and groove cedar front porch and proper weatherproofing, and basically a rebuild and re-roof of our front porch soffit/roof. The entire process from initial contact and estimate to final walkthrough and change order review was excellent. Their price estimates were very competitive and Raman is deeply outcome focused, ensuring the end result is what we discussed and expected, all in a timely manner. Final price was right in line with expectations and change orders! The team was exceptionally hard working and innovative in terms of working with the weather for a particular product like gaco waterproofing. The team was also excellent at identifying and walking us through found issues like additional rot, hard to match materials, etc, resulting in no surprises or upsets. I will definitely use Intercrus again for future projects!Posted on Carol KauppilaTrustindex verifies that the original source of the review is Google. This company impressed me every day as they removed my old deck and replaced it with new decking and railing materials. The workers showed up every day and completed the project on time. From building to clean up, they were very detailed and did a very professional job. The price was exactly what was quoted and was very competitive with other bids I received. I was kept up to date on the progress and the project manager, Raman, was a very good communicator. This company has fabulous customer service. This has gotten to be so rare, I was a bit surprised. I thought, wow, they really care about their work and reputation. I highly recommend this company and wouldn’t hesitate to use them again.Posted on Sam DarlingTrustindex verifies that the original source of the review is Google. Did a great job repairing our deck and painting our railings. Project turned out better than I expected, from the thickness and look of the layers of waterproofing material to the clean lines of the paint. Much better than our previous version, and the crew worked long hours to get the project done while weather permittedPosted on Nebojsa JojicTrustindex verifies that the original source of the review is Google. They did a deck replacement (ipe deck with glass railing and drink rail) for us. The best thing is that they addressed any concerns we had before during and after installation (even after they were paid in full and i had a couple of small things that were imperfect, they just got fixed a few days later as if by magic). There were a couple of unexpected complications during the demolition and they did not charge extra). Of course, you all want to know what the final result was. Well, I could not have expected a better outcome. See the photos.Posted on N DubyaTrustindex verifies that the original source of the review is Google. Wow, Intercrus is the real deal, and to say I was skeptical in the beginning is an understatement. I’m an interior designer and have worked in the construction industry for more than 10 years. So when project manager Raman immediately gave me three referrals from the last six months I was pleasantly surprised. After actually hearing the glowing reports I got from them, I was blown away. By the time they finished our Lake Sammamish home, we had completed three huge projects. They cranked out 1,200 sq ft of decks and an outdoor kitchen area in six weeks by our 4th of July party, then turned around and completed a huge patio, drainage, and exterior masonry project before we hosted my best friend’s wedding on August 9th. Pulling that off was no small feat, but Raman and his crew went above and beyond to make it happen. Raman’s background as a project manager really shows. His experience and attention to detail were obvious from the get-go. He turned around drawings quickly, gave great design advice, invoicing and change orders were clear and correct, and they use modern tech for billing. Everything moved at an efficient pace, and there was absolutely no way this project could have gone so smoothly without him. The level of trust I was able to have in them was so refreshing, and for a small business, they run like a well-oiled machine. As someone who “knows what she wants,” (as my subs like to say 😂), I was beyond impressed. These guys gave me exactly what I wanted. They were on time, detail-oriented, polite, and they left the outdoor areas clean when they left. We spent around $150k across the three projects, and I can say without a doubt that it was worth every penny. I wouldn’t hesitate to recommend Intercrus. Their pricing is competitive, the craftsmanship wonderful, and you can actually trust these guys to do what they say they’ll do.Posted on Roland LaiTrustindex verifies that the original source of the review is Google. Intercrus was a pleasure to work with. Raman was very responsive to all my questions and requests. My deck is beautiful, and much stronger than it was before. All this and they were actually also the cheapest quote out of the three companies I contacted. I highly recommend them for any deck project.Posted on Julie BairdTrustindex verifies that the original source of the review is Google. We had a great experience with Intercrus Decks as we hired them to repair the rotting railing and upgrade the balusters on the front porch. They responded promptly, provided a reasonable bid and did the repairs earlier than expected. Raman and his crew of craftsmen were professional and meticulous with their work. It looks fantastic and we will contact them again!

Key Benefits of Waterproof Decking: Built to Last
Waterproof decks provide more than just rain protection. It’s an investment that will enhance the appearance, safety, and value of your outdoor space. Intercrus Decks installs waterproof decking that lasts through all seasons.
Protection From Water Damage: When water seeps into deck boards and structural supports, it can cause significant damage. Waterproofing keeps moisture out. This barrier helps to prevent wood rot, warping, swelling, and future costly repairs.
Increased Durability And Longevity: Seattle’s decks are exposed to the elements all year. A waterproof system provides additional strength to withstand the moisture. Your deck surface will last longer and remain strong even in wet, freezing, or humid conditions.
Improved Safety: Wet decks can be slippery and dangerous. Our waterproof materials provide better traction underfoot. They also protect against hidden damage that could jeopardize the stability of your deck over time.
Prevention of Mold and Mildew Growth: Mold thrives in conditions of constant moisture. Waterproof decks eliminate this risk. We keep surfaces dry to protect your family from allergens and harmful bacteria.
Reduced Maintenance and Upkeep: Decks that are not waterproofed must be sealed, stained, or repaired on a regular basis. Waterproof decks minimize the need for maintenance. Less upkeep saves you time and money, allowing you to enjoy your new deck with less stress.
Potential to Increase Home Value: Homebuyers value low-maintenance, long-lasting features such as waterproof decking. It improves the overall appeal of your space. A well-maintained deck also makes your outdoor space look cleaner and more polished, which appeals to buyers.

Ask & Answered: Waterproof Deck Solutions for Seattle Homes
Can I install waterproof decking over an existing wood deck?
Yes, in most cases, we can apply waterproof coatings or membranes to existing wooden surfaces. Before proceeding, the structure must be sound and free of damage. We make certain that everything is secure before beginning the process.
How long does it take to waterproof a deck?
Installation usually takes a few days, depending on the size and condition. Weather and coating curing times can have an impact on the schedule. Our deck builder plan the job so that it disrupts your routine as little as possible.
What makes a deck waterproof instead of just water-resistant?
A waterproof deck has a sealed system that completely blocks moisture. Water-resistant surfaces only repel some water; they can still absorb moisture. We install full waterproof systems to provide complete protection.
