1. Grand Decks
Website:https://www.granddecks.com/
Address: 3055 NW Yeon Ave, Suite 643
Contact: (503) 939-3835
Hours: Monday-Saturday, 8:00 AM – 6:00 PM | Sunday, Closed
Grand Decks is made up of a team that knows how to handle minor and complex repairs. They specialize in resurfacing, stripping off your old top boards while keeping your safe foundation to save you money.
Their crew also handles localized fixes, quickly swapping out rusted hardware or individual splintered boards.
We appreciate that before starting any job, they run a complete inspection of your posts and joists to verify everything meets current codes.
We like that they back up their repair and resurfacing projects with a 5-year written workmanship warranty, covering structural defects like severe warping and shifting. Knowing you have that safety net brings serious peace of mind if the soil settles.
Just remember that they only offer cost-saving resurfacing for well-maintained structures under 15 years old. Older setups usually require a more expensive complete teardown.

A total refresh for a 25-year-old deck!
Alex and his team were responsive, reliable, and completed our project in just a few weeks.
Our cedar decks & staircase desperately needed repair after 25 years. Alex had the best bid for TREX; and from demo to completion he was up front about everything.
We are VERY HAPPY with the outcome, and can’t wait to enjoy the space again. We highly recommend Alex and Grand Decks!

Exceeded expectations
Alex and the crew did an excellent job. Starting with a very detailed and reasonable bid, everything was done in a timely and professional manner. Mine was a resurfacing, not a new deck. The results exceeded my expectations, which is rare. They also have a lot of experience with Azek all-PVC decking, which is the best currently on the market.
I contacted 10 decking companies, and Grand Decks was by far the best in all ways. If you have deck work that needs to be done, hire these guys.

2. Pacific Valley Decks
Website:https://pacificvalleydecks.com/
Address: 1720 NW Lovejoy St Ste 242
Contact: (971) 406-4009 | [email protected]
Hours: Monday-Friday, 8:00 AM – 6:00 PM | Saturday, 9:00 AM – 6:00 PM | Sunday, Closed
Pacific Valley Decks provides a straightforward upgrade that saves you the massive expense of a total rebuild. They even prioritize transparent pricing from the very start, giving you clear estimates with a firm promise of absolutely no hidden fees.
Homeowners worried about sloppy installations will love them too, as they back their projects with a 1-year workmanship guarantee.
And if your frame is beyond saving, they manage full teardowns. Most clients even noted that the team hauls away the old mess.
We also appreciate that they commit to fixing any labor-related issues if something feels off after the job. If your sub-structure is solid, their team simply replaces your old boards with new composite materials.
The only downside is their strict Sunday closure, limiting your options for weekend consultations.
3. Cascade Fence & Deck
Website:https://cascadefenceanddeck.com/
Address: 6529 NE Sandy Blvd Suite 207
Contact: (541) 779-6092
Hours: Monday-Friday, 8:00 AM – 5:00 PM
Cascade Fence & Deck speeds up the quoting process with a specialized virtual estimate option. You just upload a quick video of your damaged boards and receive a custom estimate within three business days.
They even evaluate the cost efficiency of every project to see if a quick fix is significantly cheaper than starting over. Most clients noted the honest recommendation for a safer replacement, rather than upselling.
Service-wise, their crew tackles localized repairs, replacing a handful of loose pieces to extend the life of your deck.
They also provide specific guidance for navigating tricky homeowners insurance claims after sudden storm damage.
However, they apply a steep $225 trip charge on top of actual repair costs for all service calls, so they’re less ideal for tiny, minor fixes.

Went above and beyond for our 3-story deck
Kyle and AJ did a fantastic job with our deck repair. Throughout the whole process the team was thoughtful, communicative and helped me choose the best and low cost option for reinforcing our 3 story deck. Kyle and AJ even went above and beyond and did some minor repairs and gave me some great tips on how to maintain our new deck. Id absolutely use them again for any deck work.

4. Deck Masters, LLC
Website:https://deckmastersnw.com/
Address: 1901 NE Buffalo St
Contact: (503) 724-8863
Hours: Monday-Friday, 9:00 AM – 6:00 PM
Deck Masters, LLC is one of our picks for ensuring that all construction is completed exclusively by their own employees rather than relying on subcontractors. This strict in-house policy ensures consistent quality control across every single job site.
They tackle deep structural issues, too, easily extracting bad support posts and stair stringers to make an unsafe space secure again. And if they can salvage your existing pressure-treated frame, they’ll offer full resurfacing with brand-new composite materials.
On top of that, they replace failing safety barriers with modern wood, metal, or sleek glass options. All their services make them ideal for total deck transformations, since they also work with various materials.
One catch is they operate on a strict weekday-only schedule. You won’t be able to book any weekend consultations or urgent Saturday repairs.
Customer Reviews
Super solid stairs and a beautiful custom railing
Deck Masters came right away and gave us a bid for redoing our deck using Trex materials for the deck flooring and a new wood railing. They gave us an option to wait until winter to have the work done and receive a discount, which we took them up on. The quality of workmanship is excellent. The deck stairs are solid that it literally feels like we are walking on a foundation of cement when we use them. The deck railing was a custom design, and they did exactly what we asked, and the quality of the wood is exceptional.

5. ELM Construction
Website:https://www.elmpdx.com/
Address: 12300 SE Mallard Way Suite 265
Contact: (971) 318-5112
Hours: Monday-Sunday, 8:00 AM – 5:00 PM
If you’re searching for thorough services, ELM Construction is worth a look. They evaluate how rainwater moves through your yard and drains off your structure, preventing future damage.
They then recommend practical site improvements, like redirecting downspouts or adding ventilation gaps, to stop rot at the source.
If your outdoor space feels bouncy, they perform targeted reinforcements to the underlying joists and beams to restore rigidity. They also repair failing ledger board connections and correct improper flashing.
And to protect the wood after a job, they offer full cleaning and resealing services to shield against constant moisture.
All these critical steps are super helpful in preventing dangerous water damage from seeping into your home’s rim joist.
Unfortunately, they aren’t strictly a specialized deck-only operation since their focus is on general remodeling and construction.

Beat the birthday deadline with days to spare!
I was working toward a deadline to resurface the deck before my husband’s birthday, which was only 3 weeks away. It was a long shot, but Max, the project manager, took it on, immediately calling his manager to find ways to make that deadline. He was supportive, but never pushy in helping me choose color and layout design — all in one meeting. He made sure the decking was available, brought the builder out to see the project and OK it, and arranged the start date.Today, we have the deck of our dreams, party ready with 5 days to spare!

Quick, affordable, and a beautiful upgrade
Had wood railings replaced by Trex composite and aluminum decking. The project manager, Adam Fretas was extremely helpful in my needs. He helped me with what was affordable and I got a beautiful deck upgrade. The work was done more quickly than expected. I will use this company again.
